I think I know where the OP is coming from. Taking off from the lights with what should be normal pedal travel and the car is quite slow - it takes off about the same acceleration as a Camry driven by grandma. You need to actually use a fair bit more throttle than you'd expect to get off the line at a rate you'd be wanting to - still talking road/cruising/commuting driving style, not boy racer. Being able to ramp up the %'s a tad in the lower levels would get around that issue - fine tuning it so the amount you have the pedal depressed actually corresponds to the amount you feel it should be. Casual driving - my Pajero used to get off the lights a lot quicker with the little amount of right foot that feels natural for daily driving. I guess I'm in the same boat as the rollex - the amount of throttle that's given at the lower levels doesn't match what we're used to and expect. eg - to me a couple of cm's pedal travel (no idea how far, just using that as an example) feels natural for me to take off with. To get the power that feels natural to take off with I need to use a noticeable amount more pedal. It would indeed be nice to have the thing calibrated to the point that you get the power you expect at the position you expect.
