E38 single fan control HI everyone, have an LS2, e38 ecu, I have a single thermo fan for my radiator, its not the PWM type. I have searched this forums and there are plenty of threads on it but I cannot find anyone who has had a positive result. They all say you need to use the PWM system.
Surely I can just get a signal in the settings to trigger my relay for the single fan when it gets to the required temp. Can anyone help with what settings I will need in HP tuners.
Thankyou.

How do you have the fan defined in HP tuners It should be single and discrete it doesn't matter which wire you hook to the relay ground (either dk blue or dk green) as you're only running one fan which will run at high speed when it comes on. Then set your relay control parms and control by % to what ever works best. Hope this helps.

Hi LS1 Fox
Yes I have it on 1 and discrete, the relay in the car is to the blue wire, but I have another relay near the fan. I just though someone may have the correct parimeteres to put in the PCM to get it to swtich properly.
Ill keep playing around with it.
Thanks for your input.
