I have a 96 Firebird w/ 97 PCM and a HPTuners modified program.
I replaced the harmonic balancer and now have a P0300 code. I assume that a CASE relearn must be done.
I tried the "driving" method but it didn't take.
Since the programming was done for me and I don't have HPT myself, can the HPT software do this? I.E., go back to the guy that programmed it? Or, can a dealer do this without "screwing" up the HPT program?
