Good to know, thanks for the feedback. That would certainly be a cool idea.
I am fairly certain, although I could be wrong, that he basically controlled his IAT's with the potentiometer. IE; he replaced his IAT for the potentiometer.
I have NO CLUE about this aspect of tuning....but assuming I am right about how he did it, maybe he had it set up to have a tune at say, 40 degrees......80 degrees......and like 145 degrees?
