diablo question

[SeVeReDiStOrTiOn]

I adjust my fan temps a lot and everytime I do my predator installs the whole tune. Question is...do the fuel trims get deleted when you change the handheld tune?

Good question, I've always wondered too. I think it does cause of the gauge sweep - might represent the PCM being reset?????

Edit: Always wondered if the GM oil life system gets reset too - mine has only come on once only after several months of no tuning changes. Not that I go by it, just curious.
