If I was to do a A4 to T-56 swap in a 96 Z28 would I need to use a 96 OBD11 M6 PCM or can you do some kind of programming to the A4 PCM to make it work ? If I need to swap PCM's would a 96 be the only one that will work or would a 97 also work ?

 

Any of the mail-order tuners can program your present PCM for the M6.

 

dude you can send your PCM to member tjwong on here and he can program it for you cheap! I own a shop and he does my programming for several years now, he has a dyno too so his programs are all tested!
