using the power Fc i know you can turn the fans on at certain temps but can i have them come on high at certain temps or does the ac have to be on?

 

You need a datalogit to change the temp settings.

 

I have one, i changed the fans to come on at 83C but the only come on low or maybe medium but when i turn the ac on they come on high can i have them com on high with the AC off? i dont knwo too much abou this stuff yet.

 

On setting 3 at the bottom "Fans vs Water Temp"

I have mine set at:
86
86
88

I've never paid much attention to the speeds after I changed mine. I haven't had any cooling problems so that's all I can tell you. Maybe one of the gurus will chime in soon.

 

That's weird. I guess I never actually checked what level they're running on either. I always thought the Fan2 setting on page 3 was the temperature the high level would come on.

And by the way, I really don't think you'd want to set them for 83 other than for testing. The thermostat is only trying to keep the temps at 86, IIRC. At 83 your fans would probably run all the time.

 

i Have an apeti Gt FMIC and my car runs hot and down here in texas during the summer it sucks. i think my fans run all the time anyway because when i'm driving the car is never below 94C.

 

Yep, that's the same FMIC I have. Usually it doesn't seem to hurt unless I'm boosting quite a bit though. But I don't think 94 is anything to worry about. For me, 100 is where I start looking for ways to help it get cooled back down again.

 

If you have the FAN MOD SW installed, and turn it on, it bumps the speed to the next level if it has not already been done.

There was a writeup a few years ago about how to rewire the relays so there were only two speeds: medium and high with them replacing low and medium.
This did not require the FAN MOD SW.

 

how about just high
