I've asked this in the how-to thread as well, but anyway - has anyone ever found out the PWM parameters used to control the fan? Namely the signal frequency and polarity?

Just wondering, any special tips on making this work? I.e. capping fan clutch shaft from the water pump? also heard guys say a tune was needed to reset temps? Thanks in advance.
Old post i’m aware, but, if you run the e-fan with no modifications to the tune you will run 203-208F with A/C on and 223 without it on before the PCM kicks it on to avoid overheating.

I have low speed set at 195, medium at 200 and full speed at 208 using HP Tuners.
