so I'm struggling with the logic of this os.
so pwm fan is designed to come on from 15% to 90%.

I go to the lowest setting box, like 191 or whatever it is, set it to say 30% (I've tried Lower too) then 40,50,60 ect and coolant temp goes well past 191 before it starts ramping in fan % on scanner. it doesn't really get the fan up to 30% till more like 217deg which then cools quickly back down and turns off again(below 15%) about 214. seems to not follow what I put in the boxes at all. seems like there's a filter in the logic how it ramps up the % slowly and back down again.

I'm hoping to get the car to run about 200deg. as of now I have a 180stat that really seems to open more like 197 cause that's what it will get down to cruising, but stopped the fan comes up very late and gets to 217 at a light and then swings back down as soon as I'm moving. big radiator and big fan too just can't get it to turn on to keep the idle Temps down around 199
