2000-2001 Cadillac Controllers - A communication error may occur at the end of the reprogram in the TIS software. If you receive this error once the progress bar goes to 100% you will not be able to reprogram this controller.

all 2000 to 2003 FWD Northstar PCM's interchange

1999-2003 Corvettes & Cadillacs - GM Requires that a Star Adapter be used during reprogramming the PCM in-vehicle. The controller can be reflashed Off-Board without any problems. Check any TSB's on the vehicle to be sure it requires the adapter.

The 2000 to 2003 could not be programmed in the car until the MDI came around. Some times the MDI will fail on the first attempt, but goes through on the second. If you use the MDI and the J45211 it works ok the first time.
The issue with doing it in the car is 80% with the PKIII system. If you unplug it the program goes through

So the LS1 pcm can control a N*?

So the LS1 pcm can control a N*?

s10mods come on now

The LS1 PCM was used on a 99 Northstar FWD engine in a RWD application from the factory. This was a very small run of a car.

The 2000 Northstar is very different from the 99 engine. The Crank sensors are different and the reluctor ring is cut different. The 2000+ are COP also

In 2006 they redesigned the FWD engine again and uses a single crank sensor, the cam sensor is moved to the intake cam from the exhaust and it uses a E67 ECM

93 to 99 engines are similar 93 to 95 are SD and have no MAF. You can adapt and 93 to 99 to run on the 99 LS1 program and PCM

I knew that what I ment was what did they come from the factory on? what vehicle was RWD with the N* and LS1 pcm? if it was from the factory that way, I wanted to look up the wiring diagrams for that vehicle.
