Everything I've read is the module, or whatever it's called, has to be sent off to be unlocked to the tune of I think around 2k, then spend another pile on tools to change settings,I would think Alfa OBD or HPtuners could access the set points for the fan control algorithm. One of these days I may find the time to dig into that. I’d set the fan about ten degrees f cooler if I could.
