Radiator fan control
Hey guys I’m having an issue getting the stock radiator fan to turn on at a lower temp. I used to have a mishimoto fan and I set it to turn on at like 190f - 195f on ecuflash and it worked but when I switched back to stock fan it won’t do it. It will turn on 203f - 206f. Does it not work with stock fan or is there something special that needs to be done?

As long as it it's wired into the factory fan controller, it should respond accordingly to inputs in the fan duty table.

Any ideas? I cant get the thing to start at 195 f. It wont will just start at 203f. I noticed in periphery 1 theres an option that says "2nd thermo fan table". Anyone have any idea what thats for?
Can anyone point me to the orignal fan tables found by MFRED, back in the day. I need to reread some info in that thread he originally posted with source code for ECUFLASH. Sorry, not trying to hijack.
