Thread: e67 PWM fan control not working in tune.

  1. #1

    e67 PWM fan control not working in tune.

    I have a 1962 Corvette with 2012 zl1 motor package. Using an e67 pcm with operating system 12628912. I have also installed a pwm fan controller. The fan speeds work correctly when controlling them via the HPT scanner "vehicle controls and special functions". Currently when starting the car cold the fan comes on at around 15% and ramps up to 84% when at operating temp. That's all great but I have 0% in all the tables. It appears there is a hidden table that I cant see or somehow find that is controlling the speed. Tune is attached. Thanks for any help.

    I believe what you are looking for is this.

    Thanks a ton for that. Already loaded it up and it worked. They had a regular relay on the fan but the noise just killed the character of the car. I wired up a dodge pwm module and at 50% you barely notice it. I find that changing the desired vs ect table does not do anything. Its all in the desired% VS current state. It also appears to be based on air temp. Thanks again.
