I just found the missing link!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!:D

So who want it?:D

Clarkz71 I have your your BMFX program. Thank for posting it

MED is was very easy to find!!!!!:D

About 20 minutes is all it took.

The BMFX is a leaded fuel program :D :D :yup:

I have all the programs and I think I have the libraries for it. MED stopped by today so I took a look at what I could find out on GM's side. I can down load all the files still from GM.
Some of the aftermarket programing program I have work with OBD I and MEMCAL's. Hmmmmmmmmm:D

I just have not seen the light.
I just don't think I should jump into a market that has programmers already.

MED talked me into looking at least. Hmmmmmmmmmmmmmmmm :D

I have everything and I can do a lot with them with no effort.

The leaded tunes are EXPORTS, but not all exports are leaded. They have a more aggressive tune to them.

I am at home so I can dig through all the old programs that I have.:thumbsup:


BTW ever seen a Northstar with a manual? Allante?

OK I have some new pictures.

The first is a snapshot of a WOT from a dead stop with a stock DHS program
look at how much the PCM allows for max power/torque on this run

http://i224.photobucket.com/albums/dd25/AJxtcman/PCM%20Stuff/03DHS.jpg

This WOT run is at a dead stop with a tuned PCM
99% torque Hmmmmmmmmmmmmmm:rant2:
of course this is mine!!!!:rant2:

AJ,
In my testing of my 98 STS motor with 95 pcm, what I thought was 2nd gear starts was really the torque
management killing the power. It seems to be related to a timer off the brake circuit cause I can downshift
from 3/2/1 and then go wot WITHOUT touching brakes and I get a good launch but if you hold brakes and try to launch in either D or 1st, you get torque management and a poor, low power, launch.

If you can fix this, I will be your 1st customer and be very gratefull!!

Aj I agree making a buck is a good thing, The problem your have is the same as everone else has selling a product.

Everyone is looking for number's Dyno stuff to back up your charts and personal work. Can you do better than FastChips? Have you Dynoed your own Northstar? I don't mean to question your work but I think if your going to sell a product you got to back it up with some real number. I think thats what happened with the guy that have Fastchips also.

What I want to know is the same question I have been asking. Can you build a total package? IE CHRFAB has some nice parts I want to use so I will ask you the same question I ask Wester can you tune for the cams head work and so on?

Craig


I have not seen any thing good from chrfab except the valve covers. Don't take that the wrong way I am sure that they have done great work. $1200 bill for head work that I could do blind folded. Wait I saw a blind guy porting heads once. I had an ECU on a sand rail that was programed twice and took a third time to make it right.

Let me ask you
If your PCM is limiting you to XXX ft lbs torque and you build the motor to make 5000 ft lbs how much torque will the PCM allow?

next question
If you make 100 hp at 2000 rpm and 275hp at 6000 stock Y engine SAE report
If I can make 130 to 150 hp at 2000 and 275 at 6000 does it make more power?

next
If you make 80hp @ 200 and 292 @ 6300 Stock 9 engine SAE report
If I make 130hp to 150 hp @ 2000 and 275hp @ 6300 does mine make less power?

If a quarter mile calculator says bert's aka Highline cady's DHS is producing 320HP out of a VIN Y 275 hp motor on my tune is it correct?

So do we have any stock 03 STS or DTS dyno runs?
I will put $500 down saying that my 00 to 03 program will produce more power. It may not be peak, it may not be HP but it will make more power or torque. $500 says it will. I think a VIN would be the best way to tell.

Yes I can get Cams.

10-25-07, 05:11 AM
Hmmm! Ok so what kind of package could you put together?

Yeah! it cost money to play and if your the only one making go fast parts you can kinda set your own price because your not competing with any other company.

So It sound like your want to start a side biz. So like everone else you going to have to put Packages together. Dyno number and so on. There a nitch no one doing it yet. Keep it cheap and everyone will be buying. You will make all your money in the mass's. The guys that have car but not tons of cash.

So like I said the guy that has total performance package is going to be the man! chips, cams, performance goodies IE porting and the cool shiny stuff for the bling wow factor! and if you take it one more step and do body kits ground efects.

Just look at LMC or Yearone all the resto or custom part any one could ever want.

No one's doing Cadillac's:canttalk: Hmmm.

AJ:

I'd like to take a shot at your torque questions:

Q1: "If your PCM is limiting you to XXX ft lbs torque and you build the motor to make 5000 ft lbs how much torque will the PCM allow?" Ans. XXX ft lbs.

Q2:"If you make 100 hp at 2000 rpm and 275hp at 6000 stock Y engine SAE report
If I can make 130 to 150 hp at 2000 and 275 at 6000 does it make more power? Ans. Yes, because, over time (i.e., the rev band or power band) you make more power over stock because Torque = (HPx5252)/RPM. Low down at 2000 RPM you're making from 341 ft-lbs (@130 HP) to 394 ft-lbs (@150HP) compared to stock of 263 ft-lbs. At 6000 RPM both tuned and stock motors share 240.7 ft-lbs. A quick linear graph (attached below as: VIN Y motor (stock vs AJxtcman).gif) shows more torque over RPM (i.e., rev band or power band) for the tuned motor (please note: this graph is way over-simplified with no curves but proves the point nonetheless). For reference, a 1994 VIN Y puts out max 300 ft-lbs at 4400 RPM, which doesn't help the stock motor's situation when comparing it to the tuned motors.

Q3:"If you make 80hp @ 200 and 292 @ 6300 Stock 9 engine SAE report
If I make 130hp to 150 hp @ 2000 and 275hp @ 6300 does mine make less power?" Ans. I'm tired, but it looks like the same situation as Q2, AJ's tune wins the game by using the same old torque math equation above. For the stock "9" engine: 80HP@2000RPM = 210 lb-ft and 292HP@6300RPM = 243 lb-ft. For the AJ-tuned "9" engine: 130-150HP@2000RPM = 341-394 lb-ft, respectively and 275HP@6300 = 229 lb-ft. Who care's if torque is puking out at 229 vs the stock's 243 lb-ft, just grab another gear before 6300RPM and keep on flying using the AJ tune.

Q4:"If a quarter mile calculator says bert's aka Highline cady's DHS is producing 320HP out of a VIN Y 275 hp motor on my tune is it correct?" Ans. Yes, or at least pretty close. The torque math equation above tells us that if torque goes up under constant conditions such as same RPM engine, car tires, etc. than so does HP. Math is math and you can't beat it unless it's done wrong, in which case it's not math:annoyed: Basically, it's garbage in gets garbage out, but one can put stock in math if one takes the time using decent numbers under similar conditions. You and Bert have shown this by running undeniably faster times than stock using same car, same driver, same tires, same day, and same math/quarter mile calculator - so you must be making more power with your tune.

This is not an advertisement, I'm just an enthusiast -- so here's my questions

1) Why do we all sometimes fruitlessly waste our time asking ourselves: "WTF was GM thinking?" Maybe their just building cars to satisfy the majority of customers who might not all be "hard-core" power-addicted enthusiasts.

2) Do dyno numbers give the real numbers we're interested in? Half the graphs I see don't cross near 5252 RPM. Tires and drivetrain, no air resistance, torque control systems, etc can interfere with comparing one car to another when measuring from the wheel.

3) Can AJ get that torque delivered signal to 99% for our PCMs? This comes from Q1, all the extra mod Qs, etc. The N* may truly be a wicked enthusiast motor. The graph attached below as: AJ max torque signal.jpg

I'm not writing this stuff to be an ass or endorse product. I think enthusiasts should stick together instead of ripping each other apart. We're not really that big of a family and the market is limited. You'd be far richer tuning for a host of other vehicles - most of us need to keep our day jobs and remain enthusiasts doing it for fun and having fun along the way.

med
10-25-07, 06:51 PM
"So how does that 5250 thing work again?"

Just fine. The last graph crosses at 2125 RPM because Torque (lelft side) is 2x Hp (right side) on the y-axis of the graph. Torque = HP = ~410 for this motor at 5250 RPM so it's good SAE stuff - they got to get paid too. My fault though as I misrepresented the crossing idea.
Revised crossing idea designed to increase viewer confusion of how I interpret dyno graphs : the graph's Y axis units for HP and Torque must be demarcated the same and in units of Lb-ft and James Watt's definition of horsepower :bonkers:. Now I have to call my lawyer, because I'll be in trouble with everybody:shhh:.

10-25-07, 08:56 PM
Have you Dynoed your own Northstar?

He has not.

So far only one of his customers has been on the dyno, and his PCM lost 30hp from the stock PCM.

Maybe it was faulty this, that or the other.... but until someone else goes on the dyno, we'll never know.

Well......, we do know a stock 95 Y motor makes 230hp at the wheels and
with a fastchip it makes 245hp on the dyno.




The chip from fastchip added 15 hp to the wheels and removed my top speed limiter. He had it up to 149 in 3rd gear on the dyno. The horsepower went from 230-245 at the wheels and the torque was 260 on the last pull, I can't remember what it was on the first.

This is where I'm loosing the big picture. I understand that every motor make diffrent power and part where out. So what!

Question Are being ask and it seem's where Doing the side step dance.

To me its simple. AJ's got a car It should be his test bed. There for some dyno work would be a key in showing people what you can do. Or some one else is going to have to be the test bed For diffrent year car's. Which so far has not work out! So I have to conclude, We have a lot of poor people here with Cadillac's and know way to do the testing to move this a long.

Which I feel for AJ Because its keep him from making some cash.

So some how it must move past this point or its going know where.

I don't have the Answer!

First GM produced this Magic program.

Second thing is that the Fiero guy's have been doing a lot with the 93 to 95 programs.

I just got back from the yard and picked up two 4.6L STS PCMs (BHMN and BMYH). I wrote down the VINs of both cars (I can PM them to you). Build dates of 11/93 and 06/95 on the door stickers. I picked up some other goodies, so my money be right.:yup: I stripped wood, radio, 4 sensors, but these PCMs took the longest to remove as I was on my back the whole time:drool:.

Cool,
I need to make a junk yard run to. A heater box or is it a fan box Mine is falling a part to much heat I guess. Must be a comon problem?

The yard I go to is between Milwaukee and Chicago. I can PM you the place. I'm only talking about 96 and earlier Caddies at this place. They're cheap, it's pick your own or have them do it and the 300 to 400 cars are replaced constantly....I have seen many Cadillac Devilles, Concours, and Sevilles come and go through there since summer. I don't think you'd have any trouble finding what you need. Saturdays to 3p. There just aren't many yards open on Sundays - none are that I know of anymore <-- which is hard on weekend warriors. Bottom line: there's tons of good stuff out there for these years at this time. Good luck with your heater box issue - if it's the plastic outer cover you're talking - if it's under the hood on firewall with blower motor then I've never seen one that's not cracked.
Craig: Do you have an OBD-1 N* also?

95 STS, Yes under the hood. I'm in AZ If I was closer I would just go and see AJ and see for myself. I assume your doing the dyno run to see what you gain in performance?
Any way we have a ton Of Cadillac's. Retirement central don't you know! The bad part is they drive them so slow:banghead: What a waste of a performance ride.

Yes, common problem. As med stated you won't find a good used one.
You can get a new one part # 52491785 at GM parts direct for $75 plus
shipping. If you go to a local GM dealer it retails for $125.

I don't know. I wish AJ would chime in on this kind of stuff. I'm not exactly a dyno lover, but I am certainly interested and willing to learn. I thought taking it to the strip was the way to go, but everyone's all about dyno. This thread is cool as it deviates and then gets back on track.
That info from Clarkz71 was golden concerning the heater box/blower barrier thingie. It seems some underhood rubber and plastic parts have a harder time than others - I think it's caused by underhood heat also and it appears to be independent of climate. I'm sure those parts will be sought after as the years go by. Too bad they haven't been improved upon or some way found to protect them from going bad.
Anyway, I'm getting off track. Let's get the high drama of PCM tuning back in this thread.....AJ?

Hmmm! I don't know!
I think the performance guy want's number. As he add more and more parts tell he get to the goal HP. The drag guy wants to have better Times as he add's parts or tunes for HP. And the rest just want a better running car, Which if it feels better your good to go! That would fall in to the Road and Track area. Which if you want to get pickie you can do tests for that too.:thepan:

Just my take on this whole thing.:yawn:

So from my post's I want number's and a Goal of a Total performance motor.

The rest of you guys will have to decide for your selfs:hmm: as to what you need.

"Well when I'm in there I might as well up grade something "

How about you dress up that barrier to give it that carbon fiber look!:histeric: You'll be the one and only with that piece on your firewall and you can snub everyone else's cracked version whenever they lift their hood at shows etc. Maybe black chrome or something indestructible like stainless steel (too pricey to tool up for) or gold foil heat shield or custom high temp paint (Imron, etc)!:cool2: I'm just joking around here, so I hope no harm done - I gotta go back to work:cool:.

Seriously though, I hear you about getting things done while you're in there though - I tend to lose a lot of time cleaning things up just because I am into it (i.e., easy to get lost). You could go crazy and polish any aluminum you see till it's a mirror and do some switching from GM satin black to gloss for serious reflection between the back of the motor and firewall.

Don't get me started on changing stuff to make it easer to get to parts!:thepan: GM sucks at it.

This is not a total rebuild or I might!HEHEHE! I'm not made of money I got to many fires going allready. In my Garage I have a 89 project truck my son has a 89 project truck Father son thing! and a 23' Ft project boat. All of which where beater. So I got them all cheap.
My STS is red was super clean All the options sun roof black leather seats
Just needed the tran's to be done. In fact its still in the shop trying to fix the shifter problem.
Anyone know where I can get a new one?

"Anyone know where I can get a new one?"

New what? Trans? Brand spanking new? or used? Price quoted this weekend at a yard for $350/used transmission (3.11 or 3.71 ratio 4t80e) completely separated no warranty pick up only in WI.

Anyway, I stopped by to see AJ today. He has the PCMs and is excited. He is also very busy:sneaky:which is good as in good things come in time. I left him to get his work done as I tend to get long-winded. I also looked at the exhaust side cam/lifter/tappet issue and I'm siding with AJ -- it exists. It also explains redesign to rollers. How to cure that problem with flat tappets I don't know. Oil thickness (fix by sumping? if due to starvation), high heat condition (reflow cylinder head?:banghead:), ZDDP/additives lacking:bonkers: (Clarkz71?), or dare I say crappy motor and just give up altogether. Just some thoughts.

Run a good diesel oil, I use Rotella 10/30 and/or use GM EOS or the
Valvoline synpower additive.

Watch out. Gm has discontinued EOS and the new versions of Rotella have
less ZDDP than they used too. There are some aftermarket ZDDP additives
that u can buy- really good for pre 2000 N* engines

Your almost correct, GM is releasing a new formula EOS. Part# 88862586
It is reformulated to satisfy the EPA. Still good as an additive though.

Same with the Rotella, less ZDDP then the old stuff, more then SM rated
API starburst oil however. So it's still better for 99 & older Northstar's.

I just got a e-mail back from Wester and for the way I want to go with my Engine they said to work on the Exhaust side of the cam. Also have been talking to a pcm company to see if I can replace the Cadillac unit with there unit. Which they offer some direct replacements for gm car. It sound like a lot of work but I got time to burn there software is plug and play which I like so we will see.

Yah. The added lines help to compare the graphs of the 2 motors. LD8 spends more time (over the RPM range) above 250 ft/lbs (never below?). Both motors seem to be best in the 3200 to 4400 RPM range. It would be nice to overlay graphs, etc. to see which gives best area under the curve.

Anybody know where I can get a used transmission pretty cheap? I'm going to sell the car but the transmission is out and I figured I'd get more out of it with a cheap transmission installed. If I have to pay 2500 for a new transmission and only get 3000 out of my car then its not really worth it.
