E-Fan Conversion Question

[MichEnvoyGuy]

Im having the fan codes eliminated in the tune I just ordered for my '02 I6.
So Ive been thinking about the e-fans lately because it sounds like something that would help me gain an mpg at least and maybe a few hp's. Ive read a lot about it here and the other site.
So I get the fans, the setup kit through pcm4less and then I need to buy a fan controller with a probe that I wedge in the bottom of the radiator. I dont want to have to wire a switch in the cab if I dont have to.

Question: How does the controller know when to come on when the A/C is on then? Does the controller get hooked up somehow to the a/c clutch or something?

If you're getting a controller that uses a probe between radiator fins, it's got a thermostat that keys off your radiator temp. If you want it to kick on with your AC compressor, you'd need to add some wiring and a relay yourself, or find another controller that has that functionality to it.

My controller has ignition and A/C inputs. The ignition will only allow it to run when the engine is on, and the A/C will run at a 50% duty cycle when it is on. I have neither feature connected, but at a red light, the lack of airflow will not make any cold air.

Mind sharing what type of controller you have?

Delta Current Control FK-55. Expensive and it took me forever to get mine in the mail. Customer support is 0. Works great, though.

Thanks. I dont care so much about how much $, as long as it works and is reliable/durable. So you dont have the A/C input hooked up? Any reason you didnt hook it up?

The DCC controller does have an a/c input. Here's how I installed a C6 Corvette efan.

I don't sit in traffic too often, and if it is that hot outside, I would prefer 4/60 air.

Ok gotchya. So it can be hooked up. Just out of curiosity, what would you hook the a/c input to? Sorry for the million questions but I dont want to start buying stuff if its going to be too much for me to handle.

Air. Then I connected the IGN to +12.
