I made an observation this weekend on my car and want to bounce off the brain trust here on the M5 board. I took off the air intake plenum off for some maintenance work so can see the throttle bodies from inside the car. I then wanted to see how much the throttle bodies open relative to pressing the gas pedal. What I observed is that even not in sport mode, the throttle bodies open up very quickly relative to pushing the gas pedal. Specifically, at approximately 1/3 of my gas pedal travel they look to be approximately fully opened. Not a precise measurement, I know, but I don't see any actual movement of the throttle bodies at any position above half throttle. In Sport mode they open even earlier. This is does with the car off and key in the "run" position, and I don't have any codes/ issues with throttle control. However, this just doesn't make sense to me because wouldn't you want the throttle bodies open proportionally to the pedal for best control, so that if you move the pedal from lets say 75% throttle to 100% throttle, the throttle bodies move proportionally. I don't believe that my car has any tunes on it, but I am a bit puzzled.
