Working on a 2003 s10 that i swapped a 2003 silverado 5.3L into. Still using the factory 03 s10 blue/green pcm, but the donor engine tune as they shared the same pcm service number.
i changed the tune for drive by cable and a few other things. Filled up my AC and the compressor clutch wont kick on. I changed the AC type to analog cycling as its wired with a low and high pressure cutoff switch, just like the factory s10 was. The S10 was also set to analog cycling, so i figured it should work.
I can command the compressor clutch with the controls and it kicks on just fine, so i know the wiring side is correct.
attached is a current copy of my tune. do i need to change something else besides cycling type?
