I am only a dumb leco but I am interested in what makes my car tic now my tuner who looks after my car explained to me a custom tune resets the parameters for timing, mixtures, idle etc to levels that he uploads via the flash unit to the car computer I get that part. I am trying to understand how the computer decides for it's self (depending on how you drive) the parameters it will use to drive the car why wouldn't the parameters set at the time of tuning say 6000rpm be different say months later in it's setting I just dont see how the car can vary an uploaded program so much?

Funny thing a couple of weeks ago the idle on the car started sticking and being erratic consulted the forum for advice cleaned the T/B and disconnected the battery for about 2 hrs took the oldgirl for a spanking and it went like the clappers dont know if it was the cleaning or resetting the computer by disconnecting the battery but the change was massive. It felt crisper definately quicker maybe I should reflash the custom tune and see how it goes.
