    Just curious, why the forced fan with TPS? Is it to head off a problem?

    Two reasons, first I see it as another safety measure to guard against overheating, though it's very unlikely that it would ever come into play. Second reason is for bracket racing. I had first tried code that forced the fan off at high TPS, but that lead to a lot of temperature variation between runs. My truck is very sensitive to temperature variation, with times varying + or - .030 seconds with just 10* of temperature change. By having the fan stay on during runs, I was able to achieve much more consistency between runs. This was also coupled with closely monitoring temperature and trying to always start the run at the same temperature. You will also notice that I have the Fan On and Off temps set very tight, this was for the same goal.
