I read a faq somewhere that shows how to use a turbo timer to run the
after-run cooler....  however, it might be easier to just put a trigger
in that kicks it on at a lower temp, like maybem 180 degrees instead of 220.

mine comes on once in a while but i almost always let the car run for 1
to 2 minutes at idle before shutting it off
