Running a Northstar on a LS1 PCM.

[AJxtcman]

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

I have an 01.....That would be sweet!

[Cadillacboy]

that sounds a cool project !

i though the STS had it first because it was possible in 02 while the Vette and STS had it standard in 03?
Awesome news though AJ still kickin ass!!!

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

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
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
That is a 52% gain.
Hmmm. 52% gain on a 300 HP Hmmmmmm 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

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.

So this may look pretty good with this kit added?http://www.angelfire.com/stars/mycad...rgerphotos.htm

This is almost done.

[msta293412]

What do you mean "This is almost done"? ...Where are we with this? really?....

[AJxtcman]

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. 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
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
