I am having an issue with my radiator fan. When I turn on the car the radiator fan will turn on and does not turn off. My coolant temperatures displays the temperature. could I still be having a faulty etc? tested the relay and its fine. any suggestion on where is the problem? additional info: a friend re flash my ecu using HP tuners but he tells me that HPT cannot control the fan activation
VICTORY!! thank you HGT, here are the values that my tune had
this issue was driving me insane, replaced the values with the ones you gave me and it works like god intended. perhaps my friend forgot that he changed all those values because he insisted that it was a hardware issue.
I also have another issue that perhaps you could recommend a solution:
while my car is cold 92f to 150f the cars idle soulnds like the car have cams, this is also something that started when this same friend changed the values for my fan. when the car passes arround 150 the car goes back to a normal idle. any ideas?
Anything over 55% sounds like 100% and your lowest was 60% duty cycle.
Regarding your idle issue, monitor loop status and see if it clears up when going from open to closed loop.
