i recently found out that my pcm is dead. it won't take any programming changes and probably hasn't for as long as i've had a flashing SES light (16 months). will an OBD 1 pcm from an impala work as a replacement for mine? obviously the pcm from the impy was for a car with an auto trans, but i'm hoping tunercat can get around that. we have a tune up ready to load in the new pcm as soon as i get it, so i'm hoping this might be a cheaper alternative than the stealership.

can anybody tell me for sure if the pcm from the impy will work?

 

Yes, last four of the part numbers should match. 8051 I believe. Once you load your program, the auto tranny will be no problem.

coolness...i'm picking up my new PCM tonight.

 

got the PCM last night. the last four numbers of the serial number are 8051. it's in the car and will get flashed today or tomorrow.

 

It should work just fine. Just make sure you load up a M6 car instead of an A4 car tune (if you need one, I can send you one, I have both 94 and 95 stock tunes for A4 and M6). I am actually running a 94 Fleetwood PCM in my car, thanks to my PCM frying back a couple years ago. It's funny when you read my file and it tells you that I have a 4 door Cadillac (I'm too lazy to edit the VIN to my car's).
