Bump....anybody able to comment on the long term reliability of the aftermarket units?
@Biggiesacks 1st of all thanks for documenting all this so far. Is that Gates part still alive 26 months later?
Also-
Looking at the options @ Rock Auto (filtering by Evo of course), the Gates p/n is FCM102 and it says it fits Base Lancers and Outlanders as well. Mitsu has one p/n for the Evo, and one p/n for the lancer/outlander. Hope someone can confirm FCM102 is good, and not a catalog error.

FCM102 Is what I have, and It's still going strong. IIRC the FCM102 has 2 fan outputs. My OEM unit had 2 outputs in the casing, but one was a blank.

Nope just plug and play. I used evoscan to test low and high fan speed, and it worked fine. 105+ degrees, stop and go traffic, a/c full blast, no problem*.
Total speculation, but maybe they plugged it into the wrong fan port or something? Not saying it couldn't be a faulty unit though.
* Yet, Of course I will update this thread if anything changes.

This thread makes me glad I then have a spare left over from chassis swap. Had thought of turfing it but nowadays I'm keeping all Evo parts.

**Update** The Gates controller has failed. Even better, the OEM controller is currently no longer available from Mitsubishi. I'm going to give this repackaged Orielly's unit a try and cross my fingers.

I will update if/when this unit fails.

The controller allows the ECU to control the speed of the fan with a very low power digital signal. You could think of it as a relay that toggles off and on very fast. Over time, the average on/off time is what controls the speed of the motor.

I am still using the original Fan.

so you can add a relay to the output? I see some digital controller kits with relays like this

You need to be more specific about what you want to do with the relay. The output of this controller was meant to drive motors though. You wouldn't want to try and trigger a relay with it. What you linked is a relay driven setup, it can only do on/off. This controller allows that plus speed control. So Off / Low speed / High speed

The ECU is sending a PWM signal to the controller. You can't control a relay with this signal. If you wanted to try and trigger a relay with the output of the controller, IMO It wouldn't really solve anything. If the controller fails you are still stuck with the same problem of the fan staying on.
The stuff you're linking is meant to replace the ECU and take control of the fans directly with a straight on/off mode of operation. If you are willing/able to remove the ECU from the control loop, then you have all kinds of options.
