A question that is hard to know the answer to unless you have studied it and I haven't. This applies to late model Bimmers with Steptronic transmissions.
Most know that have driven a step that the kickdown switch will supercede the Steptronic manual shift mode. If you floor the car in manual shift mode, depending what gear you are in, the car will downshift as with Sport and Drive modes. Here is the question. Does anybody know if right at the point of depressing the kickdown switch...just before, if the throttle body is wide open? Or...is the throttle butterfly in the electronically controlled throttle body only wide open beyond the kickdown when the pedal is all the way to the floor? The reason I ask is when driving the step in manual mode and getting on it...I many times prefer to be in a taller gear then what kickdown would provide. I wonder if the throttle is wide open just before kickdown or if there is more throttle left after the kick down switch is depressed.
Anybody know?
Thanks,
George
