: Running a Northstar on a LS1 PCM.

It has been done and I have the program.
I need to look at the LS1 program closer and I have contacted a company for some help.
As we all know the 4T80E is a FWD trans and the LS1 is a RWD car. Also I need to look at the way data is transferred between the PCM and the ABS. The other module should be ok, but the PCM ABS has multiple data lines.

Too bad the Corvette never ran MagnaRide. Because of that this setup will not work on the 02 and 03 STS models with MagnaRide :helpless:

I will clue you in on more information.
I did not want to speak out of turn. The Horse and Cart thing.
.
This program Originated at GM on a 4.0L with VIN 9 cams in it.
The 4.0L had 250 HP
This program with the intake cams from the L39 VIN 9 made 320 HP
That is a 70 HP gain with just two cams and this program.
This is a 28% gain:shhh:
Next they ran a Blower on it and made 380 HP out of a 244 CID engine.
Yes it was only 60 more horses, but I think it was close to being tapped out at 320 HP.
That was a 130 HP gain :eek:
That is a 52% gain. :histeric:
Hmmm. 52% gain on a 300 HP Hmmmmmm :hmm: 456 HP + the increase of cubes from the 4.0L to the 4.6L might squeak out 460+ HP with a blower.

Remember This is a GM setup.


I will post a LINK soon

This is a good review.

Then came the Series II plans. If you read the first review you would know that this would never happen.
The Cobra-like Series 2 is the successor to the ultrafast Series 1, which employed a carbon-fiber shell on an aluminum honeycomb frame. Under the hood, a supercharged Oldsmobile DOHC 4.0-liter V8 packed more than 400 horsepower.

11-17-07, 10:00 AM
I have the GM program

I have paid for the Harness and PCM

The harness will be here Monday or Tuesday

I will program the PCM and send it to Bill @ HP Tuners

I will work up Schematics for 93 to 99 cars and 00 to 05 cars

I will program a second PCM and start working with the Class II and UART serial data lines and messages.

Currently this a RWD Manual trans program. I have seen the LS1 Editing files in a demo version that allows you to switch from an Auto to a Manual and viceversa. I hope Bill can do this with this program. :stirpot: This should be no problem because it is an LS1 system.

I can get a stand alone trans controller for about $800. You can run a paddle shifter if you want.

Ok it looks like it is far from done, but it is on the fast track down hill.

I had the program, but they ran two completely different PCM's between 98 and 99. This is a car that has 98 and 99 build history.
I finally got the PCM model year and the part #
I will have the schematic done by the end of next week:bouncy:
The best part
I am getting help from the pro's to finish it. I think that will be the fastest way and the best way.

To me this is almost ready. Remember this is a GM program built by GM for a performance car. Think of it like a Corvette PCM running a Northstar. Wait that is what GM did. Corvettes have all the same models and systems. They even have Magna Ride:stirpot:

GM and Shelby had it working!
This is not some program I worked up.
I am about 75% sure GM ran this PCM in a FWD Northstar. It never made it to the road, but I think this is part of the 00 to 03 technology.

WTF:helpless:

I have a harness and PCM coming from a E-bay seller. I bought the Harness and PCM from the only one that had one listed with the engine. The Kit did not sell so I got the harness and PCM. He had only one more setup. Also he said he was the only one that got the engine, PCM, Harness, Clutch, and Bell housing.

I have made countless calls to get this information, but the Shelby Series one is a mess. I don't think any one other than the plant had the schematics.

I am sure it was designed for Corvettes. If I find the time I will look it up.

Not sure about which it was designed for... But the first car that you could buy Magnaride in the world was the 2002 STS. Corvette lovers had to wait until the next model year.

While we are all busy hacking up and swapping PCMs

Has anyone considered what it would take to convert a CVRSS car to a Magnaride one?

Lets say I have a set of bad CVRSS shocks and will have to spend a fortune on new shocks anyway... Magnaride would be cool...

The LS1 PCM has been hacked into. That PCM and a fully aftermarket tunable program is one way to make a caddy run hard.:D

I have a few small bugs. I got the rest of the piggyback harness done. I am running two PCM's. I push out a pin in the jumper and had no charging system. I just fixed it. It is insane fast. BTW 158 top speed.:hmm: I was under the impression it was 200+.
My VSS signal is messed up so 35 mph = 158 in the Shelby PCM, but the stock PCM shifts at the correct speed. after hitting 158 it will cut out:histeric:

I will be posting more today and tomorrow

Yes this will take a trip to the dyno.

I have the schematics for the following

99 Seville -- Low (PPL 401)----- High (YEL 400) This is my car
99 Carmaro -Low (LTGRN/BLK 822)--- High (PPL/WHT 821)

I visited my brother in Portland and it was wet and slippery everywhere by foot or car. On the rainy side of the mountains (coastal temperate rainforest) -- with superhuge slimy snails:cookoo:, wet slippery leaves, turns, and huge changes in elevation I took it easy. I can see how you have to learn driving sideways out there:yup:. Sorry for rambling, but those snails really creeped me out and were everywhere - kinda like driving on a road covered completely with earthworms. I for one love videos of powerslides, drifts, etc especially with a nice recovery. A screeching tire's a happy tire. Have you ever thought of taking that car to a Road America club event or to New Glarus for their city-sanctioned hill climb? <-- That would be some sweet and condoned video.

I could set it up to run on a stock STS, but it would be like how mark has his in his STS turbo. You would set DTC's like he does, but if you wait a short time I will be able to use nice tuning software on your PCM.

work is slow, but I am doing ok.

Life is good.

I have met some great people here

Life is good.

I cross my fingers life is good and I get my aftermarket tuning software. Please.

This is a nice car.

You may wonder why I spent so much time on this.

I was not selling enough Tuned PCM to the Caddy guy's
I was trying to look at the fuel and spark tables to turn my car up a notch.
I need to make some cash to support my tuning efforts.
The Northstar's in sand rails, street rods, Fiero's needed something better than the current sources of aftermarket PCM's. I worked on a $25K sand rail with a Northstar. Those guy's have $$ to spend.
The list goes on.


I have not removed my Caddy computer yet, it looks like I can set the LS1 up for an auto. It is all in place just set to manual trans.

Mark my word the was the 1 biggest step to getting a program built to program Northstar PCM's the correct way. Not screwing around and screwing up PCM's with GM's program.

The Shelby Series 1 is one beast of an American automobile with 320 horses a top speed of 185mph and a note to sixty in 4.5 seconds. This special Shelby was also faster than the classic Shelby Cobra 427. To no suprise, one of the few produced was wrecked when the owner of the limited muslce car was speeding excessively and struck a curb. As a result , the Shelby was shot a total of 4 into the air when it then struck a telephone pole. The pole then became dislatched and struck the bag of the vehicle as evident from the photos. Even more amazing, the driver from Reading Massachusetts escaped the crash and walked on his own to the ambulance! Luck guy...

The stock 4.0L made 250 hp
Shelby claimed 320hp with the VIN 9 cams and the LS1 PCM.
Shelby claimed 370hp with a blower and a "dirty tune" (X-50 package)
In 2001 a customer placed his Shelby Series 1 on a chassis dyno and found it delivered 270hp at the rear wheels.
The numbers on the certificate accompanying the engine package promised 370hp. The normal loss on a manual trans drivetrain is about 10 to 15%. this would put the car at 320 rear wheel horse power. :histeric:

Hi I just found this thread through google and am very interested in your progress on this project.
I am building an Open Road Race unlimited class car. I will be building a twin turbo northstar hooked to a porsche 930 trans with the ring gear flipped to run mid engine so no tranny control would be needed .
I will be using C4 Vette hubs and spindles so I can use an abs sensor for VSS input to the pcm.
I was planning to use a megasquirt system but would rather have the reliability of a factory system if possible.
Are you planing to sell the program when you are done?? and will it work on a 96 northstar engine?
I was also born and raised in SW washington and a dealer tech since 1984.
Here is a pic of the type car I am building

http://www.mantacars.com/images/be006.jpg

and the rear suspension I will be building for it

I am shooting for a 240 mph top speed (and can actually do it legally in Nevadas Open Road Racing)

Mark my word the was the 1 biggest step to getting a program built to program Northstar PCM's the correct way. Not screwing around and screwing up PCM's with GM's program.



This Program has change the way I can work with Northstar PCM's.

If I pull in some customers that have Northstars in non Cadillac's I can effort to spend money on the Cadillac Northstar PCM projects.

If we or I can raise the outlook on the Northstar by allowing for a GOOD tunable PCM that will run correctly you will see them in more hot rods. Yes 2006+ have been tuned for a few years.

This will raise the prestige of the Northstar, raise the value of a Cadillac, and may lead to people developing fixes for know issues.
Examples: Norm's Head-bolt Inserts, TimeSert Big Inserts.

Someone that is an engineer or machinist may have a project in his garage (33 Chevy or a 39 Cadillac Sixty Special or even a 1957 Eldorado Biarritz) and wants to update the chassis and drivetrain. This guy looks at a problem as a problem solver. He may design a new head gasket or intake manifold.

Corvette Guy's are installing modern Chassis and Drivtrains under older C2 and C3 cars

Fiero Guy are goofy. I am not a big fan of the car, but the guy's on the Fiero site build and design very nice stuff

Example: Russ544 has put together a Multi (8) throttle body Northstar! (http://www.fiero.nl/forum/Forum2/HTML/087315.html)

I could set it up to run on a stock STS, but it would be like how mark has his in his STS turbo. You would set DTC's like he does, but if you wait a short time I will be able to use nice tuning software on your PCM.
Yes I said a short time.

Mark99 has claimed it so dont shoot the messenger
but the reason why we revel at his STS so much (i mean more so then for simply the reason its turboed) is that his OBD-1 PCM is spidered into the stock harness and programming so well it DOES NOT throw any codes...

flyinlow
01-13-08, 02:50 PM
I assume that the PCM will still be tuneable with normal LS1 tuners since I will be twin turbocharging it and building it for Open Road Racing, so I will need to dyno tune it when done
Plus of course eliminate all emissions sensors, rear O2 sensors and Vats.

I have a basic price for the PCM with a loaded program.
This will be for the 96 to 99 Northstar with a manual trans only.
$499 plus $50 core charge on the PCM.

An Auto program is soon to follow and a 2000 to 2005 will be out also.

This is not for a Caddy, but I have my foot in the door with Wester's.
If you are a Hot Rodder this will work perfect. You can run an non Electrically controlled Auto trans with this PCM

With this tune you developed will it be possible for me to run the engine "stand alone" with only me hooking up a few wires to the engine. I have the shelby PCM and the wiring harness. Will I need to gut the harness or will I be able to just tie up the "leftover plugs".

Hey guys, I finaly got to drive my little mid engine Northstar powered Mazda pickup. Look on page 9 of this thread if you want to see old pics of the truck. I'll try to post some more pics and info later on when I have the time.
I did install a single turbo just to see what this thing was going to do. I didn't run a whole lotta boost but what little I did run was awesome!!!!!!!!!!!!!!! 6lbs to be exact. I can go all the way up to 35lbs but I dont think my stock engine will stand much more than that without scattering a bunch of parts all over the road!!!! Im going to build me a good stout engine when I get all the bugs worked out.
Lyndon Wester at Wester's Garage did me an LS1 ECM with a turbo tune. I cant even begin to tell you all what this was like. I was expecting the truck to spin like crazy but I was amazed. The tires are 235-50-ZR18 Firestones . I thought if it wouldn't spin the front end might come off the groung but it didn't. It just took off like a rocket and pinned me back in the seat without any wheelspin at all. I dont think the truck weighs much more than 2200 lbs not counting the northstar engine and tranny.
Right now I have a 3.11 gear in the 4T80E tranny but I've got a 3.70 Im going to change it to later on. Lyndon wasn't able to get the tranny controls working in the LS1 ECM in a reasonable length of time so I went with a stand alone Power Control Solutions - Transmission Control Unit which is very tunable. I think I might like it better anyway. I can change line pressure , shift points , TCC , tire size, VSS and gear ratios and such. This control unit will let you have a performance calibration and a normal driving calibration with a flip of a switch. (A) for performance and (B) for normal driving.
I got to drive this thing about four or five times up and down the road in front of my shop before it decided to twist one of the axles in two. This thing has an awesome amount of torque with the turbo. Im having another set of axles made as we speak. Im giong to try some 4340 and have it heat treated this time. The axle shaft is what broke not the joints. The stock Caddy CV axles are definitly not going to be strong enough. Anyone got any ideas on stronger axles?????
I hope AJ will chime in on this one. He has a lot of experence with these engines and ECM's . I'd like to know if he's made any progress with his super charger for his Fiero to.

Hey AJ do you have any pics or a website I might go to to see these flanged axles. I might be able to make some of this stuff myself. I also am a partner in a machine shop but we dont do splines. We have 3 CNC lathes and 2CNC Mills. I can do splines but the way I would have to do it would take forever.
My buisness is the Garage buisness, I've did that for 40yrs. I furnish the building for the machine shop and dont do a whole lot of work in there.

Hey Eldorado, the turbo is a (Super T70/T3 Turbo Charger 4" .70 AR Stage IV 35psi) and I think you mean intercooled in stead of water cooled. You dont have to run an intercooler but Im sure its worth a little more horspower.

No, I mean the turbo isn't water cooled. You'll have to idle it for 30 seconds before turning the engine off or you'll coke the bearings. Water cooling eliminates that and makes for a better "daily driver".

T70 is a little small but it will give you plenty of midrange torque.

Nice job on the install. Looks very clean. What did you do to the throttle cable to get it to reach?

mazda1949
05-22-08, 12:14 AM
The throttle cable and the gearshift cables made me put on my thinking cap. I used the throttle cable housing from the mazda on the gas pedal side and the caddy cable housing on the engine side. I used a section of 1/4 inch stainless tubing in between which ran down the frame rail under the truck. The Mazda cable had a nut and stud adjuster that hooked to a bracket on the mazda intake. I welded a short section of 5/16 inch tubing on the front end of the stainless tube so I could slide the mazda cable in for the adjuster. I used that end to take up the slack and have some adjustment. On the other end I simply slid the caddy cable housing inside the 1/4 tube until it butted against the mounting part of the caddy cable housing. I was able to buy the inside stranded cable in one long peice and crimpable ball ends and barrel ends to complete the job. I couldn't find a cable housing long enough so I just made my own. I know this was a long explanation but you asked!!!!!!!!!!!!!! Ha Ha
I used a console and shifter from a 1999 malibu and believe it or not the cable and housing were just barely long enough and worked perfectly.
My original plan was to run twin turbo's and I might still do that. I think two of the turbos like I have would be more than enough. You sound like you know quite a bit about turbo's. This is my first. I've got a lot to learn.
Im an old dirt track round D round boy and never fooled with turbo's until now. A turbo is the cheapest horspower I've ever bought. I couldn't beleive how much more power it gave my northstar with just 6lbs of boost.
Thanks for asking about my little project. Im real excited about this little ride. Its going to be a sleeper when I get the bed cover on.

I hope Im not boring you all with all this stuff. Im just kinda proud as I get stuff accomplished. Im 59yrs old and am surprised Im still as ambitious as I am.
I get my new axles back today I hope. I hope they are stronger than the last ones I had. Maybe the heat treat and harder metal will do the trick this time. I was going to up the boost a little at a time and am sure the axles need to be strong enough for that.
Also I am going to be installing a blowoff valve (BOV) in the next day or so and I'll show some pics of that to.
Now to the prayer request. Im sure this forum has beleivers in prayer and its power!!!!!!!!!! I was diagnosed a month ago after a CT scan for a kidney stone which I passed within an hour after I got to the ER to see if I had any more stones before they let me go home. They came back 30 minutes later and told me I didn't have anymore stones but that they saw a mass on my pancreas. I have been in hospital after hospital for the past month trying to figure out if I have cancer or not. For some reason no one has been able to do or get a biopsy because of the location of the mass. The mass is plain to see with CT and MRI scans but is impossible to get to for a biopsy.
The bottom line is Im going in for surgery to remove the mass on Wednesday. This is a very serious opperation and am hoping that if it is cancer we caught it in time and it hasn't spread anywhere else.
I wanted to live long enough to see my two little grandboys (3 and 4yrs old ) grow up and to finish my truck.
Please remember me in your prayers!!!!!!!!!!!!!!!!!

If someone wanted to spend the time to sort out the Trans functions I could get this setup to run in a FWD Cadillac without any DTC's. If I could get some time I would take care of it myself. I have the PCM setup to control the engine in a Cadillac without setting DTC's and it will send out all the required Class II data messages so all the other modules will be happy and not set DTC's:yawn:

You have a 96 Y and that is a hard one to get every thing lined back up. I did a couple. #1 had a ABS/TCS message. #2 did not pass emissions. :bonkers:
#2 was a revised version and I had plans to install it in #1's car, but then it wouldn't run the OBD II readiness test that are required to pass emissions.

1996 programs are all by them selves and they take the most time to reassemble.
I think I have got a total request of 4. That is a very small number for such a hard program.

This is from a LS1 Northstar customer
I had some software issues and couldn't tune his on the spot. I left him with a Manual Trans Fiero Tune that was setup for N/A. I have a new Boost tune all finished up for him and it will be mailed out soon.


AJ, I want you to know that this program that you wrote to my ECM is awesome.
I finally figured out what was wrong. The fuel pressure was dropping to 18 lbs at full throttle. I put another pump on it and wala!!!
This thing is so fast I cant contain myself Im so excited. Its so fast it is really scarry!! You can take of from a dead standstill and it just leaps without spinning untill it reaches 20 or 30mph or so, no bog, lags or delays and then it lights up the tires. Then it takes a hold and pins you back in the seat and never stops pulling. You gotta ride in this thing now!!!!!!!!
It still has a little problem with the idle though. Stephen got the tranny shifting much much better. Hooked the laptop up and adjusted here and there with the tranny program.
Call me some time if you want. Man am I excited!!!!!! I've never rode in anything that fast!!

I ran across some 4L80E stuff in this program. :hmm:
What does that mean? :rolleyes: It means that is has an Input Speed Sensor in the trans. Hmmmm The reason the program won't work on a 4T80E is because it doesn't have the capability to have an ISS. I guess it does. :hmm: more work is Needed, but this is a big step on running a 4T80E on the PCM

I dont think it will be long until AJ has this LS1 PCM perfected even with the tranmissions controls.
I dont think I've ever saw anyone as dedicated as AJ on a project as he is. I dont think most people realize what an undertaking it is to come up with a program that will run on a Northstar. Without AJ I dont think this LS1 program for the Northstar would have ever even gotten of the ground.
I for one want to personaly thank you AJ for all your efforts so far!!!!!!!

HPTuner has been offering a tuning package for this setup for a while!

The software I own has more parameters.

Oh yeah I have HPTuners also! I know for a fact that Wester's DDT has more parameters.

Just ask the V6 guy's if Wester's/TunerCat has more Parameters than HPTuner's

So it has been a year now since Wester's set me up. I would think within a year HPtuner will have the 96 to 05 Northstar VDF's out.

I won't be able to stop it. :rant2:

I counted around 70 parameters in the V6 in HPT, there are around 300-400 in my tuner package..... Yeah, HPT is a joke in the V6 segment.... They don't care, they don't support much, they have zero plans for updates to make it better, they don't support many PCM's at all, just overall a poor offering...

He was driving drown main street and nailed the gas at 30 mph. The lower control arm ripped off the frame. :helpless: He said it got the truck stopped with out any further damage.

I think he said it was the from bracket on the right side, but this is the bracket I am talking about, just the left rear.

I have that tune file also made for the ls1 computer. A customer hired me to make a file for it back in 2001 i think?? I dont think it was made from gm. It was made somewhere for someone. The ls1 computer is not able to handle Variable cam timing.

In our software, efilive, you can transfer transmission segments from files as long as the operating system matches another you need. So that will not work of putting in a front wheel drive trans as, i dont believe there where any out there running it. The file you have is its own operating system and layout. I dissasembled it and found about 70 tables, as it looks simular to a 1999 ls1 type format, and then stopped. I only added enough to help out a customer that needed to add more fuel because his was running WAYYY lean.

Well I got the riped out spindle arm mount on the frame fixed on my truck and put the new PCM in and it does seem to be a good bit faster. Its sounds a little different and seems to have more torque all through the power range.
I have a 2800 stall converter coming within a week or so. I hope that is going to help me come off the line a little better. Im hoping by the time I come off the line the turbo will be spooled up and I can feather foot it if it wants to spin. Right now it has a hesitation and lag or bog comming from a dead stand still . Its not noticable at all just driving normal. When I try to bring it off the line it bogs pretty bad and then when it gets to about 20 or 30mph the turbo spools up and it starts to spin the tires, even though its spinning its still pulling pretty hard. Sometimes the truck will want to torque off to the left. This thing has an awsome amount of torque with the turbo. Its unbelievable!!!! I cranked the boost up to 9lbs with my new home built boost controler. I wonder how much boost this stock engine will take before I start scattering parts?
I beleive the truck will be in the middle elevens at the drag strip. We marked of a 1/4 mile in front of the shop (1320 ft) and with a stop watch it was well below 12seconds several times. This was with the old PCM so Im sure the one you just wrote will be even faster especially if I can get the lag out.

Lookin good

Hey guys , I got my 2800 stall torque converter today. I'm hoping to get it in the truck sometime by the middle of the week. I would try to do it tomorrow but I've got to go to Atlanta and see my two grandboys this weekend. A couple of weeks ago I had to go to my oldest grandsons daycare to pick him up, this is the 5yr old and he looked up at his teacher and said, Miss Janie this is my Popa and he's got a hotrod truck!!!!!!! I beleive he's gonna be a chip off the old block. He likes Popa's truck!!!!
Guys , for a stock Northstar engine with a turbo I've never set my butt down in anything this fast. Old AJ has got his stuff together on this one. He's been awful nice to work with me on my little project so far. If any of you are thinking of going with the LS1 ECM tune AJ is the man that can get you to laying some rubber down. Their is no comparison to the first tune I had on my LS1 PCM that was done by someone else. AJ's tune is awsome!!!!!!!!!!!!!
I turned 60yrs old last weekend and when I sit down in my little Mazda rear engine pickup I feel like Im in my
20's again. This is the most fun I've had since I used to drive Late model (round D round) dirt cars. I think Im going through my second childhood.
Well boys I gotta go for now . Me or AJ will keep you posted on what happens next.

Hey recheck that Fuel Pressure.
With the ignition ON, and engine OFF (zero vacuum), system fuel pressure at the pressure test connection should be 333-376 kPa (48-55 psi).

Start the engine. You should have a (3-10 psi) drop

Say your target is 55 psi WOT. Then you want about 50 psi running.

If that doesn't take care of the black smoke and the flutter drop the pressure to 50 psi WOT or 0" vacuum. This may take you down to about 45 psi running. Recheck to see if that gets rid of the flutter/black smoke/lag.

I attempted to PM you, but as I am too new of a member to this forum, I cannot sent PM's yet. Would you contact me, or provide your contact info, as I would like to talk to you about buying one of your LS1 PCM solutions and wiring harness for my 1996 Northstar. I am using a Manual transaxle, so no tranny management is needed in my case. Basically, I need a stand-alone ECM solution. I am considering the CHRFab Holley system, but I would like to look into the LS1 solution you have, first.

Willl the LS1 PCM support an aftermarket fuel pump? I am planning on using a 255 lph Supra fuel pump in my MR2 + NOrthstar project, and I think this fuel pump is actually too big at lower RPMS/lower horspower (ie not wide open throttle). THe SUpra Turbo Computer controls the fuel pump by dropping the voltage it supplies to the pump when you are not driving the SUpra at WOT. It kicks up the voltage when more gas is needed. This pump is capable of up to around 750 hp.

GM doesn't manage the fuel pumps like others, Ford does this now too. GM just puts injector characterization data in the PCM so it can compute instead of try to mechanically manage it.

GM does on the Supercharged bump up the fuel pump speed, known as a 2 speed pump. Like my SC 3800, around 125 kPA it kicks in the second speed of the pump.

GM also uses a PWM fuel pump on many other newer cars and trucks and the Fuel System is a returnless on-demand design.

This is not supported by the older LS1 type PCM.
