I think the fans in my fd are set to come on at waaaaaay to high a temperature. I can't seem to find the settings on the commander though. the pfc came with my 7 so it didn't come with the manual. I did read apexi's version on the web but still couldn't find it.... so how do I change those pesky temperature settings?

 

You need a datalogit to change the fan settings.

So for now, do the FAN MOD SWITCH mod.

 

you talking about the ac/3 mod?

 

If you car had the cooling system recall, then on the back of the ECU was a little black box. It has a wire coming off it with an insulated female spade connector, but not used.

You run this to a switch to ground. This turns the fans on just as if the car had a water temp overheat problem. If turned on for over 2 minutes before turning the engine off, the fans will stay on for 10 minutes to cool down the engine.

Search on it!

I have the DATALOGIT and my fans at 86/86/88 and I have the switch.
Still use the FMS for extra cooling if racing in the heat as it kicks up the fan speed also.

 

sweet, thanks for the answer.
