Whenever I reach about 4000 ft. my auxillary fan kicks on and doesn't shut off until I'm back down to below 4000. I've tried different the different tunes on my XCAL2, I've tried it with the stock program. The fan is even on when I first start it up in the morning, and it doesn't matter how cold or how warm it is. (about 30F in the morning, and up to 80F in the afternoon) no joke, its on ALL THE TIME. When I'm at home, at sea level, it only kicks on sometimes, while towing... so I think that would be normal... any ideas?
