"HELLCAT SWAPPED CAR How can i make fan turn on when the key is on the ON position.
I have a hellcat swap and i want my radiator fan to run as soon as i turn the key to the on position.
Anyone know how to do that? I am using the pcm to send power to the fan. i have the hellcrate harness. Just curious what setting in HPtuners would allow me to do it.

You could drop all the low speed fan temps to accomplish this. But then the low speed fan will always be on. In hp tuners hit cntrl+N and type fan or go to system/fan.

BTW there is an OBD2 device sold by zautomotive called the tazer that has a cooldown feature that turns the fan and intercooler during KOEO. Although, it requires the factory instrument cluster to be used.
