Talk about tiring. I think this should be it. I am not sure if anyone here has an idea of how much crap I have to go through. And the rpm extreme guy as well. It’s hundreds on hundreds of lines of code to sort through and watch with troubleshooting to figure out what each line is. Pretty sure we have engine rpm, ac line pressure, and coolant temp figured out in order to program the module. Was contemplating trying to find trans temp as well but I have the factory fan harness tapped as a fan override trigger anyways as a fail safe so I don’t really see a need.
