Have you used one of the DCC controllers Don ? Did it work well?
I have used it a couple of times. Works great.

I just left the GMPP fan wire unused. No issues. ECM only cares about coolant temperature.

Thanks for all of your insight Don.

Looking at the DCC controller and reading the instructions, it appears to me the fan will continue to run after the car is shut off. First, am I correct? Secondly, is there a right way to get around it?

In advance, thanks for your consideration.

It only runs for a few seconds until the coolant in the radiator falls below the set temperature. Not a big deal in my experience.

I saw the 3 different sized DCC controllers. Which one would be needed with an Entrophy dual fan radiator? There's an FK45, 75 and 95.
Thanks

I just use the 95 since I’m guessing the extra margin can’t hurt.

C7 Corvette fan
 
With my urging, one of my tuning customers installed a C7 Corvette fan in his 408 Windsor powered Ford F150 with the Holley Dominator ECU.

This fan works flawlessly with the Holley Dominator, which means it will work perfectly with all other Holley systems (excluding Sniper). Fan control was integrated with the AC system trinary switch, which enables different fan speed settings regardless of engine temperature.

He had his truck idling with the AC on in 95 degree AZ heat and the temperature never went above 186, with the fan hovering around 50-55% duty cycle.

Derp. That's a pretty easy way to do it. 12v from trinary = fan runs at XX%

Well done.

And yeah, just did a C7 fan with a Terminator in a 55 Pickup and its awesome.

Donny,

Give me a call when you get a chance. I think you have my number. If not, check your PM.

Andrew
