Hey, I'm trying to upgrade my 2001 Silverado to the newest OS I can and better electric fan support. Everything is working fine except the A/C. I can swap between my old and new PCM and the A/C works perfect.

Did the A/C change in 2002? or does anyone know how to change the A/C type? I'm using tunerpro to edit my bins and the XDF's found here.

What did the os for the 02 come from? Theres different ac types and these tables are not mapped out or understood the best.

The 02 OS is supposed to be from a 2002 Silverado with 4x4 and a 4L80e...the same as my truck but with a newer OS. The bin i used was found on here Link (http://www.gearhead-efi.com/Fuel-Injection/showthread.php?8147-looking-for-12587603-6-0l-4l80e-4x4-bin&p=77887&viewfull=1#post77887)

Both the 01 and the 02 OSs you posted use the same AC type, Analog Cycling. Looking at both OS files with HP Tuners.

Thanks so much for your help. Guess i'll set as much as i can to the same as my 01 bin. The only thing i changed on the 02 Bin after i got it from you was copying over my e-fan settings. I attached my original bin and the one i flashed.
