I'm new, so forgive my ignorance, please.
I understand devices like the Cobb AccessPort and Diablo, etc. can carry 91 octane tunes, 93 octane tunes, economy tunes, etc. I also understand at least some of them have the ability to revert a car to a stock tune. My concern is whether they backup the OEM tune for restoring later or whether they have their own hard-wired OEM tune and no ability to change.
The reason I'm asking is what happens if Ford has some kind of recommended/required/TSB-based change to performance parameters that require a flash? Can the tuners handle when the OEM tune changes?
Thanks.
