I have the ability to Recalibrate Northstar PCM's. I am working on unlocking more functions and a program to let people do it with a laptop.

PCM exactly is?

PCM = Powertrain Control Module

Jason, want to take this one?:stirpot:

I can reprogram or recalibrate PCM's to most specs. I can not finish a Package to sell yet. SOON. I will need to unlock more options. As you can see I am into them. I have completed some programming that removed all OBD II functions. This would mean it was no longer OBD II be the definition of OBD II. I have actually by passed all OBD II test. The good thing on what I did was I set the OBD II readiness codes to Pass. If you when to an emissions test you would PASS the test. Some other systems or programers just turn off the DTC's.

What kind of horsepower gains can you promise with your tuning?

o ok yea you definately need to tell us how

What are your credentials? What makes you different from the other wannabees?

What kind of horsepower gains can you promise with your tuning?

I just read "reprogram...recalibrate"

Which you can do with a tech-2, but I wouldn't call it tuning.

Ahhh, a new batter steps up to the plate. Can he hit the homerun?

Do you still retain the original VIN PCM programming in order to go back to Square 1 if need be? ......and is your hack good for post-'00 OBD II vehicles?

My Northstar does 0 to 100 MPH in 9.6 second.
I had a lot of tire spin and ran a 13.5 quarter mile.
I am a GM tech and I found away to do it. I can not say too much more. I am working on some more deffinition files.
VIN 9 are the easiest. 2000 to 2003 are simple. I have done several upgrade programs test runs. I will hunt up a 2000 to 2003 PCM work it over and take some pictures or screen shot.

As you can imagine I'm sure I'm not alone when I say I'm having a difficult time believing you. We all hope and pray for that day, but you're going to really need some hard proof to sell this crowd on your claims.

I specifically would be looking for gains in HP and torque, elimination of speed limiter, future tunability for fine tuning at the track or on the dyno. I want to see dyno sheets before and after.

I hate to seem like I'm being difficult but this claim has been made before with no materialization at all. If anyone can re-tune the N* PCM without loss of drivability or dependability that person shall be the hero of all man kind.

Just so we are all clear on the definition of OBD II.
OBD II requires that the on-board computer monitors and actively perform diagnostic test on the vehicles emission systems.
If you turn off an EGR valve you no longer have an OBD II car.
Most programmers have just turned off the OBD II monitors so a code is not set. I have a way the not only shut off post converter O2s, but set the PCM to display passed on the readiness codes used in emissions testing.

On the Tech 2 you can monitor system status (I/M Flags)
You will see a list as follows
TEST ----------------------- COMPLETED
Oxygen sensor -------------- YES/NO
Oxygen sensor heaters -- ---- YES/NO
Catalyst --------------- ----- YES/NO
Evap System --- ------------- YES/NO
Air System ------------------ YES/NO
EGR system ------------------ YES/NO

Any time the DTC's are cleared or service programming has been performed the I/M flags are reset to NO and you must perform the drive cycles.
.
I have recalibrated a 00 - 03 PCM on the bench "no car attached" and had all the I/M flags set to YES.
I rechecked the by setting it back to the stock VCI for the VIN and it showed NO.

OK well that's all fine but basically what you're saying is you're altering the emissions system monitoring to always be in the 'READY' state. So the system is no longer working correctly and wouldn't throw a code if there was a problem?

Do I understand you correctly?

Having said that what can we expect as far as performance gains? AND what kind of ETA do you anticipate to have such things available to us?

[QUOTE=codewize;1060178]QUOTE]

01 DTS would be great to show you:worship:

I will pick up a PCM set up a calibration and run a car with it first to make sure it is good. Then I will reprogram it again and reset the theft learn and mail it to you.
I have one program for a 99 Seville that I can not start the car. All 99 Seville's run PK3 correct? For some stupid reason it will not recognize it. It come up with invalid password. I have tried everything to get it started.
I will make sure this will not happen to you.

I am talking no converters, No speed limit, increased HP and not from no converter.

Do you have any IDEA why Westers want all the VINs?
I do!

This is my current Northstar 99 VIN Y Snapshots with a Tech 2
First picture is at the start
The second is at 0 MPH and .925 seconds
The third is at 100 MPH 10.577, but then you take out the .925 seconds and you get 9.652 second at 100 MPH
The fourth is at 120 MPH 14.690 - .925 = 13.765 second 0 to 120 MPH. It was still going.
The fourth was another run 0 to 102 11.102 second but I donot have the first frame so it was probably faster.
The rest is G Tech and the Tech 2

TANSTAAFL......There ain't no such thing as a free lunch...........this thread should prove interesting, for a number of reasons........Such as, If your programming runs in "PASS" all the time, is the PCM still able to control fuel rate, timing, F/A mixture, EGR (screw with EGR and you get impressive detonation), cat control, etc.? And what N* vehicle did a 9.6-0/100? Man, I hope you're on the right track.......you'll be the next Vic Edelbrock/Joe Mondello.

VIN Y.....The 275 hp N*?

No convertors? Explain how I pass a under vehicle mirror test PRIOR to OBD II plug-in.....

I left on out:eek:

The last 10 times I have been to the IM240 emissions test station they plugged in to the DLC and then checked the gas cap. I have heard of a mirror test, but I have never seen it done.:thumbsup:

Everthing I have listed is all from GM calibrations. That is the easy part. The hard part is figuring out the definition files that are different between the two and then use them to rebuild a CALIBRATION.

So tell us why Westers wants the VIN's. I have a guess. If you're willing to let me demo this thing for free I'm game but I also question the ability for the PCM to correctly control the drive-train after the mod.

Are you loading the Abu Dhabi calibration? With manual spark advance override?

Have you heard of TIS?
that would be GM's TIS that is gone and disbanded?

I have no clue tell me more.

If you're running 13.5s in an otherwise stock car, there are HUGE compromises you're making with your calibrations. GM runs the cars rich at WOT to reduce the possibility of melting a piston, for example. How are your calibrations at WOT?

There are still obviously a lot of unanswered questions here. And I know you're apparently not far enough along to get your equipment on a dynamometer. But that's what folks like us will want to see. 13.5 seconds on an otherwise stock car is 100+ hp...just with PCM calibrations. Why didn't GM runs these calibrations? The answer is likely due to longevity...something a hot rodder may not necessarily be interested in, granted.

The point is, there are a lot of things that GM accounted for when doing their tuning. It sounds like you had snow on the road...meaning you were testing in the dead of winter (great for performance). I hope your calibrations will work equally well for someone living in Phoenix during the summer as they will for someone in Ontario in the winter.

And 01DTS's question remains unanswered. If your tuning puts the OBD-II system into a constant state of "pass" or "ready", how will the system find and report a fault in, say, the EGR valve, if there is one?

i have been tuning GM for 4 years if you need any help with beta testing or dyno tuning or anything i could try to help in any way to get this to work

dyno tuning wont cost anything i will suply the dyno

jadcock; It's actually my car we're talking about.

TIS, Hmm interesting. What can we learn from that? how does the public ensure they have the latest programming?

It was much better when we had carburetors and distributors LOL

Ask youself what is on the TIS update CD's? What is on the server? why is it going away? Hmm. I know!

So don't.

Do something with it to show us.

A dyno would be good. Post a video of you on the dyno hitting 160mph without hitting a fuel cutoff.

I'd like to see a video of a 13 second Cadillac with a Northstar without the benefit of nitrous or a blower/turbo. My hoax detector is starting to twitch.

OBD SYSTEM IMPROVEMENTS (RE-FLASH CALIBRATION)

SUBJECT: ON-BOARD DIAGNOSTIC (OBD) SYSTEM IMPROVEMENTS (RE-FLASH CALIBRATION)

MODELS: 1999 CADILLAC CONCOURS, DEVILLE, ELDORADO, SEVILLE WITH 4.6L ENGINE (VINS Y, 9 - RPOS LD8, L37) BUILT PRIOR TO NOVEMBER 1, 1998
ALTHOUGH THE SUBJECT VEHICLES HAVE BEEN CERTIFIED AS COMPLYING WITH THE APPLICABLE U.S. ENVIRONMENTAL PROTECTION AGENCY (EPA) AND CALIFORNIA AIR RESOURCES BOARD (CARB) ON-BOARD DIAGNOSTIC (OBD) REQUIREMENTS, WE HAVE IDENTIFIED AN OBD SYSTEM IMPROVEMENT THAT SHOULD BE IMPLEMENTED WHENEVER PRACTICAL.
CONDITION:
ENGINE EGR OPERATION MAY BE INADVERTENTLY DISABLED BY THE SETTING OF DTC P1189--ENGINE OIL PRESSURE SWITCH CIRCUIT.
CAUSE:
VEHICLES WERE PRODUCED WITH SOFTWARE WHICH MAY INADVERTENTLY DISABLE EGR OPERATION.
CORRECTION:
USE A TECH II SCAN TOOL TO VERIFY WHAT SOFTWARE CALIBRATION IS PROGRAMMED INTO THE VEHICLE'S PCM. IF THE IMPROVED CALIBRATION HAS NOT BEEN INSTALLED, RE-FLASH THE PCM WITH THE UPDATED CALIBRATION LISTED IN THIS BULLETIN.
CALIBRATION INFORMATION:
THE CALIBRATIONS LISTED ARE FLASH CALIBRATIONS AND ARE NOT AVAILABLE FROM GMSPO. THE CALIBRATIONS ARE PROGRAMMED INTO THE VEHICLE'S PCM VIA A TECHLINE TOOL DEVICE AND ARE AVAILABLE FROM GENERAL MOTORS SERVICE TECHNOLOGY GROUP (STG) STARTING WITH 1998 DISC 18.


This is why TIS is my new best friend.
TIS is being disbanded. OLD DISK? Hmmm.

Developmental Calibration software tools? Hmmm. Guess who might have that and how They can make it work with the files. Disk 1998 #18 or later!

ok i sat back long enough to take all this in
your "graphs" are something i could of thrown together in 5 minutes with paint....
if JET and Hypertech couldnt hack it, and Jet spent 100's of thousands trying you mean to tell me you did it with a lap top and some tinkering...
no possible way...
highly unlikely...

I'd like to see a video of a 13 second Cadillac with a Northstar without the benefit of nitrous or a blower/turbo. My hoax detector is starting to twitch.

I have a sister in FairBanks. :alchi:

:crybaby: I lost another PCM today.
The car runs, But I lost communications with it.:crybaby:
The PCM GODs got very mad at me for starting this thread.:mad:
They did not remove all my privileges and will rebound. :worship:
I just can't understand why it runs and drives. My PK III module has to be communicating.
I had a customer come in and requested the speed limiter removed. No problem. I showed him my 120 MPH run and he was sold.:)

wow...
120 in a STS which is governed at 130 at least
id buy it...

wow...

THIS IS A VIN Y
It is not a VIN 9 program!

Guys, I know this is difficult to swallow at this point, and this guy is new to the forum BUT we should at least hear him out. From what he's saying I gather he's at a point where he thinks he can do some sort of tuning to these things but keep disrupting the comm signals for whatever reason.

I've heard many stories about someone doing something as small as changing the wording of a DIC message and that in itself breaking a PCM beyond repair SO. Having said all that I have my doubts also.

However, if he is onto something I'd hate to think we told him to go pound salt before we gave him a chance.

:yeah:
he may be being rather smartassed about it...but least lets see what he produces...if nothing...then he can go pound salt...

hence why ive waited so long and let him speak out before i even chimed in...
but this guy
idk seriously doubt hes done anything... cuz if he hacked it as he said id be on my way there to unlock my new H STS to a Z and get any performance mod he could push outta this...
i just find it every hard that JET with unlimited resources couldnt do it, and some guy with a program on his lap top can do anything he wants to the N*....

I am a Cadillac Dealership Tech. We reprogram hundreds of modules every year. We load the complete program not a patch into the Tech II. The Tech II saves it on a PDMCIA card. This is the complete program. Now this will go into a PCMCIA card slot on a laptop. It is an embedded file and I have acquired a program to read it. The problem is the definition files. I have started comparing VIN Y to 9, Limo to non limo, Updated cam to the original "TSB", AIR pump to twin AIR pumps to no AIR system, Converter program to non converter programs and I am building a list of definitions. It takes time. I would not have posted this thread if I could not change the speedlimiter, trans PC soleniod, EGR %, and more.

:bouncy: All us buzzards circling around may have found A Man in Havana. (old movie...) If his experiments pan out, it could prove interesting. BUT if you're in OEM or extended warranty and you mess with the PCM, I'll bet GM wouldn't give you a second look for repairs.....Of course you could always buy and store a stock PCM for just such an event....lotsa variables.

alright
ill bite
ask anyone here im am number one when it comes to looking for performance mods.
I have a 03 STS and a 97 ETC at my disposal
the 03 STS is an H car and id like to have the limiter removed and the performance mildly tweaked (only mildly because i dont want to sacrifice longivity of the car for a major increase in performance, as was stated before the N* can easily melt pistions if adjusted too much not to mention pulling heads)
Ill send you an 03 Dummy computer along with my cars vin, you update it and modify it and send it back to me, ill plug it in take her to my shop put her on a lift and nail it, if she breaks 130, youve proven your validity and im sure money will pour in from all over the forum. I highly doubt anyone else could support you or refute you as much as i can and since my car is factory bumper to bumper for another 5k its prob the best test mule, keep in mind though and i KNOW IT MATTERS, my STS is an F55 MAGNARIDE STS, not the old FE3 or F45 suspension....
If it works ill gladly pay you your fee however this is after ive gotten my pcm back and tested it because as far as im concerned i could be purchasing snake oil....
Sound fair enough? If so let me know NOW and ill will buy another PCM for an 03 STS....

PM me your VIN and I will pull the program and VIS. GM VIS is Vehicle Inquiry System. It has ALL your information I need. I will send you a copy. I will be able so to recal IPC's. That would mean set everything to 0 or what ever # I want. Yes that is included also "all the # displayed

1g6ky54983u282931

also another cool thing to have would be to disable the t/c and keep 1st gear, idk if thats do-able though...

You Have this?

Just a Note. This is from the Recall I listed earlier.

TIS is no longer and the server disc are ?????
We now have TIS2WEB and no CD's. This was done for security reasons. I can't figure out why :rolleyes:

Do you have the ability to relearn Crankshaft Position Variance?

Ohh this is getting juicy. Can I get one too :)

:confused: ETC1997, ajxtcman...........This is only slightly off-thread, but ETC opened the can of worms: Traction Control On/Off...1st gear disabled? My '02 is an H car, I drive it carefully, well, and fast. I leave the TC engaged when I feel like doing something stupid such as imitating a Ferrari on a back road. BUT, when I punch "TC off" in order to scare the h... out of a riceburner, I still have 5 speeds.....4 gears and TC lockup. Regardless of D, 3, 2, 1, whatever. I can shift up & down manually, or let "3" and "D" do it for me. How is this possible? I've searched the FSM, threads, other forums. Do I have a one-of-a-kind, or is there some secret here?

Strickley a year issue.
I drive up to 10 different caddy's every day. 99 and prior TC OFF = 2nd gear start. 2000+ does not!
.
.
.
.
I am about to show a program in a PCM and then install it in the car.

My 01 does NOT do the 1st gear disable thing either, contrary to what many people have told me it should do.

Ok I had some problems.
The program I have is saved on a disc. The last time I saved it I must not have save the fuel cut and EGR. I still hit about 135 MPH on the hoist.
first is the donor car
Next is the donor PCM
Next is the stand alone programmer
Next is it all hooked together
Next is The IM Flags
Next is NO DTC's set in the CAR!
Next is a picture of a 135 MPH cut, but the camera locked and I had to remove the battery to get it to shut down

Like said I had the EGR IM Flag off and the speed limiter.
I have to replace the pistons in that car and I will start in the morning and should have it done about 5 or 6. If I have a chance I will Take another program in and use it. I have it here at home and will check it over. I really do not want to run a new set of pistons up to 150 MPH on the first start. I may wait until Friday.

Sand Rail engine for a guy.
And yes that is a very nice blue car in the back ground. MY JOB SUCKS :rolleyes:

That's a curious vehicle that will do 127 MPH at 4400 RPM. 2:75 final drive? Why would someone screw up a '65 (?) 'Vette with a high winding engine with no torque????????? (OK... I read the post again - sorry........BTW, I had a '67 427/435 new, and like a dam*ed fool, sold it in '68) Dumb, or what?

thats a deville DTS
a vin 9 car
H tire speed limited at 130 mph
your car is showing a tad under the 130....
that really doesnt prove a thing
as i said before if you can do it lemme send you a pcm and you hack it and send it back, ill test it, if it works ill back you up on this forum...

Ok I sat back long enough, and AJs taken enough heat but it seems resolved, anyway if you want more proof of this fellas worth head over to the Pennock's Fiero Forum to see some of the sweet posts he's put up:

AJ thanks a ton for the N* rebuild post:
http://www.fiero.nl/forum/Forum2/HTML/080614.html

How's the build going btw?

not that i was giving heat...
but how does him having a DTS going 130 prove anything?

Thanks.
Yes my fast car is not a Cadillac. I was told you can not do that too many times by guys on the Fiero forum. I am not a HUGE Fiero fan, but they have grown on me. 10 months ago I would considered them junk. I had a coupe of Northstars hanging around and needed a FWD 4spd manual trans. I came across the Fiero and decided to do up a Northstar. Yes it is fast. I did it as a wedding fund and I have no intention of keeping it. I have only done top quality work on it. That is why I have Hacked into PCM's. I have not mislead anyone, but I did not answer some questions. I think That Caddy's are much better cars and the Fiero needs to have a 3.8L SC in it. I may do a RWD 2 seater Northstar or even a 4.4L SC car. I think may be a SKY. I can make this happen.

Maybe I'm missing the boat, but why are you showing us the TECH 2 scanning for codes? That tells me nothing at all. I can do that too. :confused: :confused:
<---Also a Caddy tech

I may be wrong but I think that spedo is at 135 not 125.

not that i was giving heat...
but how does him having a DTS going 130 prove anything?

I have a limo based programs. I do not mean a streched limo. I have a STS limo based program with fast delivery system. This maybe an armored car or part of a motor cade.
If you are getting shot at 130 MPH and you can't get away then 130 MPH is not fast enough.
You have seen the video of the RWD STS out running the cop in NY.
I have a german based program, but it is RHD and Euro brake. I can't get it to run. :rant2:
I can take the Fast delivery STS limo Calibration and rework it for you. I will need to reset the tire size. That car should be an 8 lug. :confused:
I have a completed Limo based VIN Y for a guy with a 03 DHS and it does not stop at 130 MPH.:worship:
How much more torque do you think a LIMO needs?
How about an armored car? :rolleyes:
Caddy's are shipped all over the world and the programs are all different., but I can compare the programs and work with them.
Now do you see why Westers wants all the VINs.:bigroll:

Maybe I'm missing the boat, but why are you showing us the TECH 2 scanning for codes? That tells me nothing at all. I can do that too. :confused: :confused:
<---Also a Caddy tech

That PCM is on the bench and the I/M flags are passed. I will show you the stock calibration tomarrow. That PCM does not need a cat, AIR system, Post O2s, O2 heaters,and an EGR. Yes the EGR was flagged in that picture.

not that i was giving heat...
but how does him having a DTS going 130 prove anything?

I have no light switch in my stall. It is shut off in the parts department. I work in the dark a lot at night.
Dark shop bright dash = bad picture.
If I use a flash then I would just get a light burst.
I will try it again in the day light

ok
well this still doesnt answer my ?
if i send you the PCM will you hack it
my car has the 17inch tire option as you know from my build sheet....
so then...

YES. Positively 100%

ok so what exactly will you do to the pcm what will be changed and what will i gain?
also where are you located?

I will remove your speed limiter, add just a little more fuel at WOT, increase trans pressures just slightly for quicker shift times. I am working on a very small and very easy to install add on PWM box to keep the T/C from controling Torque managment. This will have an on and off switch. I have one on paper and know the box I will use, but I have not had the time to hook it up and run it. Then it may not work and I would be back to step one. I have the correct PWM rate and Hertz. This can be added in line. it will work similar to this, but that work on the T/C module not the PCM.

The Tech2 is being used to transfer files only. First the files are altered the repakaged abd sent to the tech2 in a mailbox type file. The Tech2 then send the files to the Module in question. This is a very safe way to recalibrate it is a tried and proven method in use by GM since 94 or 95. Yes it was sent out before the cars hit the show rooms.

can you edit the following tables? power enrichment and pe delays high and low spark tables and main and backup Volumetric Efficiency and many others that are used for tuning

and by edit i mean can you put any number you want in any cell in these tables

I will remove your speed limiter, add just a little more fuel at WOT, increase trans pressures just slightly for quicker shift times....

AJ, isn't more fuel at WOT going to hurt power? I always understood the GM engineers intentionally ran the PE a little rich to save the pistons...but leaner would gain more power. Why would you enrichen the PE even more...won't that hurt slightly?

I am working on a list by comparing programs, so yes and no. Soon it will be all yes.
The tables on the program I have will not work without the correct list of Definitions. The definitions are my current project. I am making progress.

lets break it down.

2000 Japan KD KE KF KY KS
2000 Korean KD KE KF KY KS
2000 German or euro cars same list
I have seen Italian cars and south African cars
2000 Saudi and Kuwait cars.
I can go on, but I think you understand not every program is the same.:thumbsup:
That is why the fuel settings can be changed. What if I set it to the best on I find and the best Throttle ramp I find. This would be for the particular VIN Y or 9

That didn't answer my question. We have US cars. So whatever they run in Korea doesn't matter to us. Understanding that the GM engineers were already conservative with their PE mode (ie, "too rich" to protect the engine), won't adding more fuel be counter-productive?

and when you dl those programs though, they have the OTHER cars vin in them
dling that programming into another car may conflict with the several other modules and computers on the car...

That is not what I am working on. I have found a way to decipher the codes by looking at multiple programs. I do not have full access, but I am on my way. I may start with a Korean or a North American car and adjust what I have figured out. I an still working on other Definition files. You can change VIN's per modules as long as it can be setup for the current optional modules.

That didn't answer my question. We have US cars. So whatever they run in Korea doesn't matter to us. Understanding that the GM engineers were already conservative with their PE mode (ie, "too rich" to protect the engine), won't adding more fuel be counter-productive?

Have you ever looked at a Tech2?
Do you have any knowledge of fuel trim?
Do you understand Fuel that we have today is different BY FEDERAL LAW?
We have more oxygenated fuel additives today then 3 years ago.
Do you under stand how that effects fuel trim?
Everyone in the united states has reformulated gas!!!!
The area I am in has "reformulated gas". Just say it was standard J234 five years ago. Now we have J535 and everyone else has J234.
We see cars come in after a tank fill and a switch off from summer to winter or the other way around and it set a fuel trim code. It is not common, but we see then. We will look at fuel trim and it is not uncommon to +20%. Ten years ago +20% ment you have a probelm. I use a Korean program.:rant2:

I guess I never will get a straight answer...

All I asked was, "will adding more fuel cause a decrease in power". If your answer is, "no, because today's gas is reformulated and has more additives than it used to and it takes more of today's gas to make the same power than it did on yesterday's gas, and so adding more fuel will restore the power that was lost because of the change in formulation", that's all ya gotta say...

I guess I never will get a straight answer...

All I asked was, "will adding more fuel cause a decrease in power"....

You need to realize all the car do not have the same program in them. If i ran 50 VINs and checked the CALs I might find 10 commons and some that are singles or appear just twice and that would be just USA cars.:thepan:

wheres your addy
ill send this comp out today if you sure u can hack it
do we have a deal?

The funny part, is changing the fuel won't do anything.

He says the fuel trim is +20%. That's the PCM compensating for a lean condition by adding fuel. You add more fuel by changing the fuel table and the PCM will add less fuel. In other words, the engine would not see any net change in air:fuel ratios.

GUYS your missing all the points here and not listening to what the man is saying.

Whats he's trying to convey to us is that he has pieces of GM written code that he can employ in our PCM's. He's working on the cross reference for the definition files so he understands them better.

The Tech 2 Scantool is a vehicle to move the reorganised files to the PCM. He has some good things to work with, he sounds like he knows what the goal is he just has to work out the details. He's not 'reprogramming' or 'rewriting' code so to speak, as the others would try to do. He's using libraries of code already written and in use. Just not in our cars.

Stop trying to bash the guy and listen

I see that you are missing a little. Just two cylinders.
Say you are always adding fuel, because of fuel quality. When you are in OPEN loop or WOT you go to a FIXXED fuel strategy. It is set for + or - 5%.
now you are at the same as -20%, because 0% has adapted to 20%.

WOT follows the LTFT. If the LTFT is +20%, then the WOT/PE fuel is +20%. It's a safety issue. If the FPR fails and the owner doesn't know it, they could do some high speed run and toast a piston.

Any other Tire RPO's that I should look for.

Beginning in 1991, the speed symbol denoting a fixed maximum speed capability of new tires must be shown only in the speed rating portion of the tire's service description, such as 225/50R16 89S. The most common tire speed rating symbols, maximum speeds and typical applications are shown below:

M 81 mph 130 km/h
N 87 mph 140km/h Temporary Spare Tires
P 93 mph 150 km/h
Q 99 mph 160 km/h Studless & Studdable Winter Tires
R 106 mph 170 km/h H.D. Light Truck Tires
S 112 mph 180 km/h Family Sedans & Vans
T 118 mph 190 km/h Family Sedans & Vans
U 124 mph 200 km/h
H 130 mph 210 km/h Sport Sedans & Coupes
V 149 mph 240 km/h Sport Sedans, Coupes & Sports Cars


When Z-speed rated tires were first introduced, they were thought to reflect the highest tire speed rating that would ever be required, in excess of 240 km/h or 149 mph. While Z-speed rated tires are capable of speeds in excess of 149 mph, how far above 149 mph was not identified. That ultimately caused the automotive industry to add W- and Y-speed ratings to identify the tires that meet the needs of new vehicles that have extremely high top-speed capabilities.

W 168 mph 270 km/h Exotic Sports Cars
Y 186 mph 300 km/h Exotic Sports Cars


While a Z-speed rating still often appears in the tire size designation of these tires, such as 225/50ZR16 91W, the Z in the size signifies a maximum speed capability in excess of 149 mph, 240 km/h; the W in the service description indicates the tire's 168 mph, 270 km/h maximum speed.

225/50ZR16 in excess of 149 mph, 240 km/h
205/45ZR17 88W 168 mph, 270 km/h
285/35ZR19 99Y 186 mph, 300 km/h


Most recently, when the Y-speed rating indicated in a service description is enclosed in parentheses, such as 285/35ZR19 (99Y), the top speed of the tire has been tested in excess of 186 mph, 300 km/h indicated by the service description as shown below:

285/35ZR19 99Y 186 mph, 300 km/h
285/35ZR19 (99Y) in excess of 186 mph, 300 km/h


As vehicles have increased their top speeds into Autobahn-only ranges, the tire speed ratings have evolved to better identify the tires capability, allowing drivers to match the speed of their tires with the top speed of their vehicle.

ok
anyways
my STS compared to my ETC is a dog
i need to fix that
can you do this or not
and whats the address i need to ship the computer too...

I picked up a PCM for you today. I though I used a 99V tire and it cut at 135.
Could it be that it was on the Hoist?

QQX..Tire All P235/60R16 BW AL3 99V
thats what my car has factory but it has the 135 limiter...
i need the
QWM..Tire All P235/55R17-98W BW R/PE STTL AL3
i also need some of those performance boosts again within reason because i dont wanna risk the engine
and fyi my cars in PA i dont need cali emission...

heres a vin of a 2003 STS W rated with F55 Suspension and 17 inch tires
1G6KY54953U227322
you can use that cars programming to get the W speed rating, adapt the vin to work on my cars computer and do your performance tweaks
does that work????
thanks bro

edit

I picked up 2 more PCM's

MY point on the I/M Flags

New PCM's

The bench is bolted to the wall, because I repair 4T80E trans P0741

so can you use that vin to hack the limiter?
and when can i get this pcm?

What is the service # on your PCM?

I wished you had shown up earlier :crybaby: as I have until the end of this mouth to take the emission test and that dam code PC0153 keep intermittently showing up.:rant2:

should be the same as the part number for it
which would make it 12573503

I found my Z rated tire Y program. It is in my Fiero. I thought I transferred it over to the 2000+ program for some stupid reason. When I started the 2000+ program, but 2000+ is a different protocol. Some days I just have to much going on. I am reading the RPO I had used QDO and it is not clear on the rating. It is a 235-60-ZR16 it is either a Eagle LS or an Eagle Touring NCT3 and that is a 100W tire. I have not pushed my Fiero over 120 MPH so I do not know for sure.
.
I know you guys want to know if I have a 2000+ program done. I found the mistake and by tonight I will have it done. I am hoping to have a VIN that reads EXPERIMENTAL. If not I will have to use a W rated vin.

TANSTAAFL......There ain't no such thing as a free lunch...........this thread should prove interesting, for a number of reasons........Such as, If your programming runs in "PASS" all the time, is the PCM still able to control fuel rate, timing, F/A mixture, EGR (screw with EGR and you get impressive detonation), cat control, etc.? And what N* vehicle did a 9.6-0/100? Man, I hope you're on the right track.......you'll be the next Vic Edelbrock/Joe Mondello.

VIN Y.....The 275 hp N*?

No convertors? Explain how I pass a under vehicle mirror test PRIOR to OBD II plug-in.....

Except for the rear wheel drive...... Sush Matsubara ( driver) was a good friend of mine. He passed away last summer.

well if you need the W rated vin i provided you with one.

Mountie........Matsubara and the Fiat.........The pair took their share of records in Fuel Altered.

well if you need the W rated vin i provided you with one.

Yes that is how I found my ****up. :worship:
I thought I had it all done. The one that is driving around "03 DHS" will have to be redone.

np bro
again anything i can do to help out. im more than happy to be a test mule on this and back you on the forum, i just need the comp ya know to be able to back you ahahhaa.

I think I am going to have to END or suspend this thread!!!!!

why?

Yeah your just getting us wound up here. Whats going on?

Hes got some shit to take care of with the General
long story short, for now i will be handling his affairs about this on the forum.
hes sending me a pcm out, i will test it and if all goes well i will vouch for him and we can start an exchange of computers for "funds"
of course he will purchase a vendor status though so mods dont lock it based on what i just said hahaha

thanks

Cool. I'm all for this.

I have now reloaded the OEM calibration and will get a snap shot of the cars performance.

Do you see the note for the asterisk(*)
m4414 Calibration NOT reconized by this TIS2WEB or they are NON-GM calibrations

I will call a friend that I can use this stock program in and then the new one. Then I will prove to you that it is not hard to do it is the General that is hard to do.

stock .
.

21.006 second 0 to 100
Next program would not start the car. I will need to go back over it and make sure I can set the theft learn to AUTO LEARN.
Thank for the ride John see ya later and we will go much faster.:thumbsup:

Im confused by all of this rofl
as long as it works though when i plug it into my car i turn the key and it starts and i get that added performance and removal of the speed limiter all will be GREAT!!!
Hows that going by the way did you complete it and when will you be sending it?
Thanks bro!!!

it is done.
Some how I did not set the program into auto learn for the VTD. The pass key III system did not allow the car to start. As soon as it is ready I will ship it out and you will have it in your hand.

I will post a Comparision so you will se the time it picked up.

sounds awesome bro
i look forward to it!

WOW! Im sittin back taking all this in. Im definetly on board to see what happens with cadillacetc1997. I will do the same for whatever money he wants(within reason). Im ready to go. Would love to re-map fuel and spark timming, like 15-20 hp right there, not to mention higher line pressure for firmer shifts, and of course remove speed limiter, etc. Some of that stuff was confusing, you guys know if it works for 1997, would it work for my 2001 sts, I guess it would if he's using it for his 2003 sts.

Mmmm I cant wait. What do we think the cost to us is going to be on this?

i just bustded.

Im guessing if you have to send out your pcm, it should be around $350, depending on what can be done and how much hp can be gotten out of it. Any comments on $, and how it will be done?

yup hes making the PCM for my 03 STS, the 97 ETC already has some mild programming tweaks due to the JET chip.
as soon as i have the comp and verified it works everyone will know.
its all in AJs hands now!

I see, so he actually gets a stock pcm somewhere re-programs it, and sends it to you, is that correct? If so , what all is coming with the new program? More fuel? spark timing? line pressure? speed limiter removed? Or is it something stock, that you can then plug in a laptop and tune yourself? Witch is it?

Im sure he can, he's a gm tech.

AJ, check your personal message.

I am being very quiet. I spent 4 hrs without TIS the other morning. I had to make a promise. Fingers crossed?

lol
they have been man
im layin in wait for this miracle pcm bro!

I'm just keeping quiet at this point until ETC gets the new unit and reports back.

I have not seen a 2000 to 2003 in my stall this week. Not even a waiter. I asked my service manager for his car today, but he had is wife Venture Van. Tomorrow is another day. I hope to get a car in the morning that I can test the PASS KEY III relearn on. I checked the PCM # just in case that was the problem, but they all supercede to the same #

ok
guess i gotta wait hahaha

Im waiting patiently as well...very patiently.

Look out guys! AJxtcman know his stuff. I'll let him explain how. AJ?

No start, NO START, NO ******* START!!!!!
I spent the last several hours running CAL check and found 5 new base CALs I can get start with. The one for the VIN ending in 3U227322 Will not start!
I have 1 new USA CAL and the old one that will not RUN!!
1 Taiwan CAL
1 German/Korean CAL
1 Japan CAL
After I altered it the I thought I messed it up, but I could not start it with a stock CAL in the PCM.
I went on a search and found some more base programs.

What does all that mean?!..Please , in plain english , when are we gettin this thing?! ....sorry , Im just pumped up...

so pretty much
this isnt gonna happen for awhile huh?
my cars only got 4K miles left b4 the warranty is out and i cant be a test mule in the event something goes wrong without the bumper to bumper...

that said im still counting on you

i have plenty of warranty and have a dyno to give #s on improvements i will be your test mule i have a 03 sts

What does all that mean?!..Please , in plain english , when are we gettin this thing?!

"No ****ing start" seems pretty plain to me....

I like my cars running, thanks.:Poke:

I just got home for lunch. The CAL is done. I stayed up late to finish it. This norning I had to load it into the program to get loaded into the tech 2. It is all done and in the PCM now. My manager has his DTS at work, so I will take it to work and slip it in. This PCM will start!:hmm: I am not sure what I lost in the last translation, but that program will not RUN

ok
well im waiting bro
get it tested up asap so i can get this puppy and slip it in
im, heck the whole forum is counting on you

:thumbsup:

dude
you have it done?!?!?!?!?
if so
freakin awesome bro when can i get it!?!?!??!

I'm waiting, I'm waiting, I'm waiting.

Sexy, So what does that particular PCM provide over stock. Hell never mind, get it in a box and ship it out. We want to see the results. :)

:stirpot: After the dust settles, AJ, figure out a way to switch from "YEEEHAAAA!!" to "HoHum..." and back again in the installed PCM.........Sorry. By now your brain must be scrambled...........

It Runs

awesome
so you sending it out tomorrow?
cant wait to get it bro!

My rocket has a new problem with the head lights.
http://www.fiero.nl/forum/Forum2/HTML/082440.html

random ahhha
slow down and you shouldnt have that issue ahhahaha
anyways about that computer will you be sending it out tomorrow???

This is FRIDAY, and there are no new posts since yesterday, it looks to me like AJ has done it, and "it runs", cadillacetc1997 should be gettin it today or tommarow.....am I the only one wanting to know what is going on...some body please post...AJ?.....cadillacetc1997?......PLEEEEEEEASSS SEE?!

Woah cowboy! It's only been A DAY man! Let some time go by for AJ to ship the part and ETC to try it out.

WHAT! Hell no man. I'm waiting also. I can't wait to hear the news.

All I'm saying is it's not beneficial to post every 12 hours, "so, you got it yet, how's it work?" Rest ASSURED that as soon as ETC has any useful information about how it works, it'll be posted.

dang right!
as soon as i know what the deal is
the forum will know!

I decided to keep this PCM as a test mule. I am waiting for another PCM from THE CADDY SHOP. I have left two messages at the Caddy shop. I have a friend that work at another caddy dealer that is just 20 block from the Caddy Shop that will pick it up today yet.
This PCM has been Flashed a good 20 times. I want a fresh PCM to reflash.

My service manager want the program now.

ok np
keep me updated as i am waiting for it!

I hope to get it out on Saturday. FED EX.

awesome

Can this apply to the 05+ STS V8 RWD?

Can this apply to the 05+ STS V8 RWD?

GM LAN system cars are WFO using EFILive. I may start working with GM LAN cars after I get this all worked out.
first is the 2000 to 03
next will be more on the 96 to 99
then the 04 to 05 FWD northstars
by that time the GM Lan cars will look like the easiest. :D

Hi, I'm new to this group. I own a 95 eldorado northstar car. She was running a little rough when I put it in reverse or at low idle in drive. It also popped sometimes. I figured it was the plugs, wires or maybe fuel filter or injectors. I took it to the dealer and they charged me $750 to change the plugs and wires. I thought this was a little high but the svc mgr said it took 4 hours of labor to do this. Does anyone know if this sounds right? Or next time I will do it myself. He said that I wouldn't be able to do it myself because I had to lift up the back of the engine.

Thanks in advance!

Mike

you many want to make a new thread in N*
this thread is about aftermarket tuning

Awesome
so anyways did you mean this Saturday as in today i would get it
or next Saturday?

Your right jadcock...I need to chill....I should be embarassed acting like up:that, my profile even sais right on on it, Im 34 for cryin out loud, Im married, have kids ,have a mortgage, etc......HAVE A 2001 STS THAT NEEDS MORE POWER!

I never heard from John Sidesky at the Caddy Shop about the PCM.
I have been loading more programs and need this as a test mule. I will get one and send it out. If any one else wants one I will need a PCM. Email me.
I think I have the general taken care of.

I have spent about 4 hours today on a DHS program. This will be a Y engine

Can any one tell me what cars came with Z or W tire

QDC 235/60 ZR16 AL3
QDO 235/60ZR16 HW4
QVF 225/60ZR16 AL3
QNI 225/60R16-98W HW4
QWM 235/55R17-98W AL3

? QLD 235/60R17/X WS1 ALS??

QDC 235/60 ZR16 AL3
QDO 235/60ZR16 HW4
QVF 225/60ZR16 AL3

those are all Zs
hence the ZR

so how long now till i get this comp?

I will call him in the morning.
Z no longer is a speed rating.
I would like to know what cars in what years had what tires.
example 99 ECT had QDC tire
My little rocket will be in the 8s from 0 to 100 mph I just ran 9.248 second

I will have a PCM in the morning.
The highly intelligent Tech across from me misdiagnosed a starter for a PCM. The car got both. I will swap it out with a bad one.

freakin awesome!
waitin on you bro!

Can this apply to the Northstar in the 05+ RWD STS?

AJ...I want one, I couldnt e-mail you, the system started my posts over. Please leave me detailed instructions on what you want me to do, and how to do it, cost, etc. I want to get the ball rollin even though cadillacetc1997 hasnt reported back on anything yet...I trust in you.

This was answered once. Read back a few posts

Can this apply to the Northstar in the 05+ RWD STS?

i havent reported anything because i havent gotten the computer yet to report

I understand that cadillacetc1997, I was just trying to make AJ feel comfortable, and let him know we trust him.....Looks like he's gonna overnight you a unit any day now.....Im wiggin out here. HA!

I am at a loss without any PCM's to send out

i thought you said you got one from someone who ordered the wrong part?
what if i get one?
why not just send out the original...

The guy across from me would not give it to me. The parts guy that does warranty returns was gone. He came in today. I Have been busy and it might be later today before I get to it. If anyone can find a used PCM and want to send it to me Great. The guy at the Caddy Shop has not gotten back to me yet either.

Ill search around
i dont mean to call it to question but youve been promising this PCM for 2 weeks....
what guarantee do i have that if i buy this PCM and send it to you it will work let alone get it back?

I truly dont mean to be rude though....

Hmmmm
I will.
I think the Guy across from me damaged the PCM by connecting power to it backwards. He did not want me to have it and said he was going to drill a hole in it.

how do you connect power to a pcm backwards...
the pcm plugs in using a main harness plug, it will only plug in one way...

The box used to reprogram it.

Heck anyone can get pcm's, theres an oline site that has them for our cars a dime a dozen. Let us know what you need AJ, we want to get this thing.

GET A PCM TO ME
.
The guy is not that dumb the PCM is bad. When you turn the key to the on position it cranks over. You have to turn the key to the off position to get it to stop

What adress do I send it to?, what exactly happens when you get it? Give me details, Im not playin around.

I so want to see this done, but it's not a simple process.

This isn't "tuning" as HP tuners would define it.

This is reprogramming a factory computer with another factory calibration that would not have been loaded unless your car was being exported to Germany (for instance). If you're on the autobahn you don't want a speed limiter kicking in at 110mph ;)

TUNING is changing the AFR, spark timing, shift points... a lot of things that won't happen here.

Read this thread FROM THE START.

I did. I want the finished product (just like everyone else :) ). I'm in your cheering section. I'm about $700 in to HP Tuners right now and they outright swore off the N*. I want the GUI and all.

Most GM engines have rev limiters as well as speed limiters. You may be hitting peak RPM vice peak allowed speed. TC (usually) works on revs, not speed. Hit a set rev limit and spark is retarded.

Here's a vin for you, 99 SLS.

Now the problem is Code deffinitions. THAT IS WHAT I AM WORKING ON. You will not have a different VIN or You may get a different VIN. This is an example

Identifying Duramax Diesel Aftermarket Power-Up Devices TSB #06-06-01-007
Installed Power-Up Kit
Aftermarket power-up kits have become a very popular add on for performance-minded customers. These devices can add horsepower and torque and can add additional stress to the engine. These aftermarket calibrations take the Duramax™ powertrain outside of its design torque and horsepower rating. They do this by altering air/fuel ratios and injector timing, resulting in excessive cylinder pressure and temperature. When these calibrated parameters are altered, it will upset the design balance and can lead to a reduction of engine life expectancy. Generally, in inspection of Duramax™ engine failure due to power-up failures, two or more cylinders will be affected.

Installed Power-Up Kit
• Once installed, the calibration may mask itself with the factory original calibration ID and may remain the same.

• A Tech 2® will not positively enable you to identify the use of a power up device.

• Some companies that offer power-up devices claim increases of 150 or more horsepower and 300 or more lb/ft pounds of torque.

• A vehicle that is used to the power-up device potential 100% of the time will see earlier engine wear and breakdown.

• A vehicle that takes advantage of additional power, but on a less frequent basis, may not see premature engine wear and breakdown until later in the engine's life.

• A vehicle not pushed to its limits of the power-up device often may not encounter premature wear and breakdown until after the engine is out of warranty

If I look at several Calibrations in this software for long enough I will see a blur. Just joking I see differences between Y and 9 Vin's, S rated tire, H rated tires, W rated tire, AIR with or without, Dual AIR pumps, with or without Catalyst. You can follow me know?

The sad thing is that Northstar Protocols are all by themselve. 4.0L are even different.

A diesel is not a gasoline engine. If you think you can get 150 "extra" horsepower out of a northstar, I've got some beachfront realestate to sell you in Nevada. (I'll sell it cheap, because I've got connections.)

I don't really care if we call it tuning, tweaking, breaking, hacking or what have you. If it works and we gain something without compromising the car, we have won the battle.

I lost track of all this. Where do we stand. The last I knew we were waiting for another PCM to show up and would be shipped to CadillacETC1997.


EDIT : OK I'm caught up now

Yes I need a PCM

This is from a GM TSB. The point I was trying to make is that the STOCK VIN and CAL ID can stay the same! This is used to MASK the custom Calibration!

SEE The highlight

AJxtcman, keep up the good work. I'm with you. If the other tuner guys read this thread they might get some kind of vibe that there's a market for the N*. As you can see everyone is excited so keep that in mind when reading comments.

I don't really care if we call it tuning, tweaking, breaking, hacking or what have you. If it works and we gain something without compromising the car, we have won the battle.

Make friends with a cadillac tech and tell them to reprogram your vehicle with a german export calibration. Voila, no speed limiter.

I wouldn't call that "winning" because you still can't tune for cams, or exhaust, or custom intake manifolds, etc... See what I mean? It's not tuning if a dealership can do it, and it uses factory programming. HP Tuners, etc modifies the factory program to change the air fuel ratio, spark timing, revlimiter, etc etc.

your point must have flown completely over my head. I still don't understand the significance. Are you saying there's some 96 STS with 400hp from a performance tune out there that reads as a stock calibration?

YOU ARE COMPLETLY INCORRECT!!!!!!!!!
First: some German cars have V rated tire and will not go 140 MPH!!!!
Second: What the f*** is the only Mechanical difference between the 9 and Y!
............ THE CAMS. That would be tuning for cams from the factory!
If I can see the difference between the Y and 9 Then why can't I go Further?

I do not know of one Dealership that has the Program that I am using!!!!!!!!!!!

Now for the Duramax.
I see a lot of Duramax's with altered programs or add on programmers.
After a few tuner customers blew motors the aftermarket Guy's got very smart. In the past even back in the 80's the aftermarket programmers proms or programs could be identified very easily. If your car broke. then manufacturer could say they would not cover the repair. A Duramax installed may cost 10k out of pocket!
ARE YOU FOLLOWING ME
Now the aftermarket programing companies are reusing the factory Calibration ID's and VIN's. This is to trick the dealers or the Manufactures so they will have to repair the damaged part.
DID YOU FOLLOW THAT
THIS HAS NOTHING TO DO WITH HORSEPOWER.

Yes this is a 150MPH VIN Y

Now I over lay this ontop of a V rated tire and then I know thw code for the tire.
I can also take this and over lay it so I can see the differences in the cam programs between a VIN 9 and Y.

Quick questions
Who built the program that is used in the LS1 packages?
GM or did GM outsource it?
The aftermarket Programs just alter it correct?
They don't start from scratch correct?

Valium.

You said "some", which means finding a german car with a W rated factory tire (or whatever) on ebay and borrowing the VIN.

There is more to it than just finding the differences between the calibrations. You need to find out what those differences are. Say you have a block of hex. It's obviously a table. But what table is it? Fuel? Spark? Transmission upshift? Downshift? maybe something completely worthless like EGR % vs RPM.

Are you going to start changing values to see what it does?

I'm curious now.

or I could just give you the VIN's

Hey I didn't get it :( What gives?

This looks better

I would still like details on what the pcm will have upgraded when I get it back. Again....a/f ratio change?, spark timing advance?, torgue curves? line pressure?, speed limit delete? How will it work with my mods? etc. This still hasnt been answered clearly....OR......am I getting a stock pcm that is NOW tuneable? Please in laemens terms.....Thankyou all......

I will make a very stock unaltered calibration for you. It will have all OEM specs in it. Since line pressure should stay close to you application or it will adapt it right out and set a DTC I will leave it alone. Since the timing is Adaptive also (northstar has it) I should leave it alone or the adaptive timing will think it is running on 86 octane and set a DTC for Knock sensor performance I better not touch it either. I don't have a list of mods done so I better leave that alone also. I am not sure of your tires you may have H rated tires and I would hate to have one blow out because you went over the speed of the rating for your tires. .
.
.
I say within a year I will have a program to sell that you will be able to make your adjustments with a laptop..
.
.
Ok how about I set your car up with multiple parst from OEM calibrations that I can EDIT.
How about A/F and trans PCS for a 50 foot limo
How about Speed limiter of a QWD tire
How about timing of the quickest ramp that I have.
.
.
I am still working with the Program and learning it. .
.
BTW I can call GM and get a speacial calibration called a VCI #. If you change tire size you can get a VCI #. If you change CAMS you need a VCI #.
.
If I can call them and tell them I did cam swap XXXXX then they give me a VCI # within a minute. I need to give them a VIN and other info, BUT THEY HAVE THE SOFTWARE TO SET IT UP AND THEN I DOWN LOAD IT INTO THE CAR.
.
.
Who is to say I don't have some software to that!!!!!:want:

Do you all remember that 20 second 0 to 100 SLS that I posted the snapshot from. Then I had a no start with the new PCM. I have it now with my program in it. I will try to snap shot it. Traffic is bad right now, But I am going for it.
.
.
i will post it soon

This is the same 02 SLS. I ran from a dead stop to only 92 mph Because of traffic. It ran 14.978 from 0 to 92. I have the other snap shot at home on my PC so I can not find the time at 92 MPH and show how much it picked up. I will later tonight.:thumbsup:

Now! I'm even more lost that I was before. Are there encrypted messages here?

Now! I'm even more lost that I was before.

I can help.
.
Send me a pcm and you will love it.
.
That is the bottom line.
.
It will not be a OEM, Factory, or GM calibration that any car left the factory with.

The 96 - 99 pcm are still on the burner right?

I'm also interested in a reprogrammed PCM, and am watching this discussion with great interest. What I would be looking for:

Speed limiter delete
Corrected shift points (My car shifts at 6300 and fuel cut off is at 6500, shouldn't it be 6500/6700 for a 2000 STS, 8/99 build date, VIN # 1G6KY5492YU144325)
Eliminate any torque management, also maximum shift speed/line pressure when shifter is at 2 or 1
Most aggressive factory fuel/timimg curves available (My N* is tuned for regular, I would accept having to run midgrade/premium)

Any particular PCM I would need to send you, and is used OK (can I pick one up from eBay or a junkyard?)

Edwin

The 96 - 99 pcm are still on the burner right?

I started with 99 vin Y in a FIERO.
I have a few things that I can do.
I can only do a few more things to 2000+, but that is what the call has been for. I have been spending my time on that program.
If you get me a PCM I will work it over and then send it back. If you are not 100% satisfied I will try again if you would like.

Were you running a vin 9 calibration on a vin y? That would allow you to pass 500 rpms above the rev limiter.

Im still waiting on this pcm?
whats the deal?

somethin smells, and i think i hear cowbells

idk what to believe
the proof seems solid
however he keeps stalling...

The engine had 4557 miles on it when I pulled it out for a bad casting. I patched welded it. The coolant in between the layers was contaminating the weld. I was using a alloy product from my local supplier. The small leak soon spread to a 6" long Fish Scale like area. Ever time I thought I had it good some coolant residue would come up. I thought I had it good and so I installed it in the car. I was being rushed. The f****** idiot across from me wanted the engine support that I had the powertrain unit on. I installed the engine to give him the support table and had never pressure tested the block. It leaked at the head gasket. I dropped the powertrain out Pulled the head off and found that the layers of casting split all the way to the deck surface. I head back to the welding supplier to get some type of cleaner or flux. He called the manufacturer and they told him I should not use this product on this alloy block. I dig all my wire feed crap out to weld aluminum and get a some old alloy wire I had. I cut about half the wire off the roll and grind all the crap off the block. Reinstalled the head and pressure test it:thumbsup: . Good to go. I had never driven the car off the lot with the coolant leak. I changed the oil and had everything taped off when I was grinding and welding. :confused: I had just ran the engine a couple of time with the leak.
After I Reinstalled the engine It sounded like it may have a misfire. I ran it to the Exhaust shop to have two little mufflers put on it so I could hear the car run. I had a Misfire in #7. Pulled the plug, then swapped it with #5, checked the wires, swapped out the coil assembly, and checked the injector. I found nothing, but when it missed I could hear an exhaust change. The miss slowly went away. If I would drive the car it would come and go. I cleaned the injectors twice. The more I drove it the less it happened. If it did miss it would stop if I let it idle. If the Torque Management kicked in it would misfire about 80% of the time immediately following that and I would let it idle about 15 second and it would be fine. Sound like a poor connection:thumbsup: . If I make a sharp turn or U turn it would misfire about the same. I would just let it idle and it would clear out.
.
Last night I was collecting more data on the program and about 100 MPH it shift back into 2nd for 1 second I let off the gas and then replanted my foot. ran it to 136 MPH and backed it down I over shot the first drive way so I drove down to the second drive way. I was at a cruise of about 35MPH. I did my U turn and it started to misfire.
.
This is a 96 to 99 replacement engine. I have been wondering what could be the cause. Loose wire in my custom built harness? How about oil in the intake? The oil build up in the intake is cause by two thing first is high RPM ( I have that) the second is a baffle problem in the rear valve cover. The valve cover only has 5000 miles on it. You have to have both to get that much oil in the intake that it would slosh to one side and then misfire.
.
This time the misfire did not clear up and it started to knock like a spun bearing or something in a cylinder. I limped it back home about 1 mile and it did not get better.
.
I think it stuck a valve open and if I had to guess it is #7 cylinder. I do not understand why a U turn would cause a valve to stick.
.
I pulled the power to the coil and cranked it this morning and it has a cylinder with low compression.
.
I am headed back to the dealership this morning to check it out.
.
In the snapshot I got it showed the PCM shifting 1st, ...... 2nd, ........ 3rd, ...2nd, 3rd............
.
I had taken someone for a ride yesterday just before 5pm. Nice customer. I had mad a comment that I thought I heard some type of exhaust note difference from side to side, but I did not have a miss and it was very smooth.

I am selling it at the end of the month and was realy pushing that deadline.:mad:

The base program was an VIN Y
.
.
If you tune a LT1 The base program is an LT1. If you program an LS1 you may start with an LS1. If you are tuning your LS1 PCM you are using a LS1 base program. If you have an LS2 the program is for a 6.0L not a 5.7L and you would start with a LS2 program and adjust from that base program.
.
If you wanted to waste time you could take a LS1 and rework it to a LS2 and then rework it to your preferences.

Can everyone follow me on this.
I am not just loading an OEM calibration in a PCM and then charging you $1000.

If set the code for w rated tires and that is it. We would be talking a small donation.
The more time and efford the more I would request.

ok well as soon as you find a pcm cheap which works let me know and ill pay for the pcm you program it send it out and if it works as i said ill pay you your fee. thats been my offer this whole time. but were still waiting the entire forum is and as i said not to be rude but the more and more and the constant delays makes it seem like your less than legit.

man ive kept quiet pretty much this whole time (i think) but i gotta say something. this guy is rambling, he makes no sense. ok so he knows where to get software, he knows how to load software. but it seems to me that someone questions him and he replies with something like this

If you tune a LT1 The base program is an LT1. If you program an LS1 you may start with an LS1. If you are tuning your LS1 PCM you are using a LS1 base program. If you have an LS2 the program is for a 6.0L not a 5.7L and you would start with a LS2 program and adjust from that base program.


this to me is rambling and proves nothing. i hope noone pays him in advance until we see lots and lots of proof. i can see this being one of those cases where a guy builds trust then runs off with a bunch of peoples money (think approximately 300 dollars and assume about 15 guys pay in thats 4500 dollars, imagine in he charges 4 or 5 hundred and more guys fall for it)
