I am basically buying all the go fast parts off a buddy and he is taking my stock stuff (Cam, Valvetrain, mass air). Would there be any problems with the car not starting, or anti theft if we swapped pcm's since he already has a tune on his combo? I know on fords if you swap the pcm a dealer has to reprogram the anti theft module with 2 keys and im not that familar with Gm computers. Thanks for your help guys.

 

Yes, you would have to peform a VATs relink and a Crank Position Relearn and have your VIN burned to your pcm. Somebody with a Tech 2, HPTuners, EFI Live could do this for you.

 

If you go to the dealer you will loose the performance tune.

 

f-cars use a VPW vats system, so you can swap from vehicle to vehicle without any relearn.

You would need to make sure both are the same setup, as far a m6/a4 and the vin's will be incorrect, but the vehicle's will run.

Both cars are M6, so then it shouldnt be a problem. I just didnt want to have the check engine light come on for no reason because of the swap. I appreciate the quick reply, Ive been following these boards for awhile but I dont post because im always busy.

 

How do you do a crank sensor relearn? I never had to do that. Maybe thats a issue with mine.
