I'm new and need to figure out here to start,,,2004 grand am gt
i really want to tune this pcm but i need the pinout,,,then i'll ask more questions after i build the harness. has anyone been able to tune this pcm yet? where would i be able to find out this info if it's been done. ive done a volvo ecu but that was 12 years ago and i cant remember what i did exactly. m4.4 i think it was called...it was for a 97 volvo 850 t5. anyways..thank you
