What primarly use are these for? Sorry to sound like a noob.

Seen a few videos, can you alter engine timing with them? Then flash it back without damaging the ECU?

Or is it just basic stuff that's not in the actual menu screen on the Heads UP Display?

If car is under warranty can they tell you've accessed it?

If I tested this, has anyone? Is it interesting?
Quicker throttle response. There's some dead spots between the input and the output of the throttle. Sort of a lag when accelerating.
Is this similar to what your talking about?
