Hello,
New to HP tuners and I am needing a little assistance, I am installing a GM remanufactured VCM in a 1998 chevy van with a 4.3. The original ECM was unreadable so I cannot read the vehicle info to write the info to the replacement PCM. Furthermore the reman ECM still has info programmed in it from a 1998 Chevy truck with a V8.
What do I do next? Any help is appreciated.
