I spent some time surfing for what I felt to be an easy question, with no definite answer.
So, quick question.
I'm swapping the 4.3 V6 in a 2002 Chevy Silverado to a 5.3 LM7. I'm using the factory 4L60e.
My parts vehicle is a 2002 Silverado ECSB. I've swapped in the wiring harness, engine mounts, throttle cable, and some other minor parts for the V8 swap. The drivetrain swap is complete, as well as the harness swap. I just have to finish putting everything together.
Question is: I have both PCM's. Which is the best choice to use in this situation? I'll be using my new HPTuners to work with.
Thanks in advance
