I have a friend that went and bought a '67 pickup that someone has done a engine/trans swap on. The engine is a 5.0 with the 4L60e trans from a 96 C1500. The truck runs, but he's having problems throwing codes and check engine light. So he calls me for ideas, long story short, the PCM was not retuned to run in a standalone setup like this. I found out that the 96PCM is not supported for tuning, and it was suggested to me to find a 98-00 PCM. I found a 99 PCM at a wrecking yard for next to nothing. So now I'm trying to figure out which pins need to be moved on the 96 harness to match the 99PCM. As you can imagine most of the emmisions systems were removed because of being put in such an early vehicle. It still has the front O2 sensors but nothing else. Once I do the pin changes, I need to find a stock tune for the 5.0 and 4L60e. If someone could direct me to the pinout changes necessary and someone I could purchase a tune from for this application, I would appreciate it. I do have a V2, so I can do the flash here.
