correct me if im wrong
once the car is hooked up -- the test plan will indentify the new component(s) and upgrade any other that is deemed "necessary"
the new version of software will contain all the downstream changes -- this should incorporate all the "fixes" (patches) that were applied in the previous versions. this shouldnt be a "real" bad thing, as anything from 32.1 and up is pretty responsive.
i have 32.1 and its pretty nice and i did have a chance to drive the '07 model (prior to its release in late '06) and yes the throttle response is different.. but it is a lot "smoother....
but from my understanding when the Integration level is updated all applicable software is brought to the current level also
that why i hesitate when thinking of taking the car in for issues -- it runs good as it is..
