this is my last minor bug on my2003 5.3 swapped ZR2 s10.
2003 s10 zr2 using a 6106 pcm (blue/green) thats drive by cable. donor motor, harness and PCM were from a 2003 4x4 silverado and drive by wire.
In order to get my analog AC system to work i had to run an express van tune, when i use this tune my trans will not shift gears in 4x4 low range. If i run the donor silverado tune, change it to drive by cable, the trans shift fine in low range, but my AC will not work. I have tried (2 years ago when i did the swap) to change the AC settings but they didnt work no matter what it was set on. At the time it was hot and i wanted AC more than low range. so i went with a van tune and have been running ever since.
well now i want the last of the bugs worked out. Is there any way to set a van tune up for 4x4, so that i can get low range to work 100%? Im not seeing anything in either tunes that would allow me to enable 4x4. am i missing it? or is this something support can change for me? or is this not a changeable option in tune?
i will add both a silverado tune that i setup for the truck to start and run and the van tune i have been running on for a while.
Thanks!
