High Speed fan tuning?
I am told that out of the 2 fans on the cars the BCM controls the low speed fan and the PCM controls the high speed fan.
Seeing as my car no longer has VATS and all the other gear and is running the PCM on its own, I am left with only the high speed fan values.
What I need to know is what is the lowest temperature the high speed fan can be set at?
