I doubt it takes more than a few miles for the "adaptation" to occur given that it is usually tied directly to ecu learning in other dbw cars from what I know.I too would prefer cable throttle.
This whole adaptive driving thing, I believe it goes something like: if you stay in the lower RPMs ALL the time, the computer may boost more performance there. But I wouldnt know how much the average human can perceive this, unless maybe perhaps there are 2 cars of the same make/model/trim, similar milleage, stock. One car has been driven around 1/2 throttle most of its life, the other not even 1/4 throttle.
in cars with AT and ecu learning that adapts to driving style a bit (including when the car shifts), it's a more noticeable change than in a MT car where there are only minor timing and throttle application changes among other things that aren't really noticeable at all.can you clarify what you mean about the shift changes being noticeable? thanks for all the feedback everyone
