Well, I got the controller installed today. Seems to work great and the install was very easy.
You're right about the fan cycling though. The only thing that bothers me about the controller is that after I cut the car off, the fan stays on. Which wouldn't be a big deal if it just stayed on for 30 seconds or so. Instead, it stays on for 15... Cuts off... Kicks back on again after another 15 seconds... And does this until the temperature eventually gets low enough.
Of course, this happens while the car is running as well when the temperature is right at the limit of where the fan should be on / off. But that doesn't bother me quite as much, although I'm sure it's harder on the fan motor.
I believe I can add an additional wire from the 12V ignition source that will keep the fan from coming on when the ignition is off. I've just got to call Flex-A-Lite to be sure I'm doing it correctly since their instructions are a little vague on the subject.
I would rather have this than the single speed though because the Taurus fan pulls so much power on start-up if it starts at 100%.
