I have 2009 silverado 2500 6.0l 6l80e trans OS 12630501. It had mechanical fan on it and we installed a factory efan setup on it because of the body lift on it.
We have the pins in the correct location to ground the relays. I can turn them on and off with efi live scan tool. I cant find any where in efi live to turn the fans on with the program. I applied the patch. Any ideas . Thanks.
tune file is attached:doh2:

Patched the fan ...

PWM % breakpoints are:

Fan 1 OFF = 40%
Fan 1 ON = 44%
Fan 2 OFF = 85%
Fan 2 ON = 90%
