Hello , when you are tuning with the Predator , you get to the question about the cooling fans. I want to make my fans come on sooner. The Predator ask you to adjust it + or - up to 20 % vs the stock ecm.
If you want to make them turn on sooner would you go up or down % wise ?
I'd guess positive. You could always max out the % in both directions to doa trial and error. If you're at stock, and go all the way positive and the fan kicks on as soon as you start the car then you got your answer. If it does not, then try the most negative and try again. My tune is set to kick on immediately and I hate it. As soon as I start the car it kicks up a cloud of dust.

I found it in another post last night. If I read correctly it is positive. You are actually increasing the % the fan comes on at certain temperatures.
