    Using an obd2 scanner to check throttle position while driving. Noticed that at full throttle I was hitting 91.8%, sometimes 92.2%. Is this normal?

    I've heard this before, and have seen it in my own logs some time ago.

    I do think it is normal, not sure why. It may be the torque limiter in the lower gears. Have not checked the logs for the higher gears.

    I have seen this in my Porsche as well. It will only show 100% throttle when the car is up over about 6000RPM. Below that the best I have seen is about 88%.

    Gotta love these computer controlled engines.

    I'd have to check my old logs too, wasn't this issue one of the sales points for the Sprint Booster?

    Hmm, wasn't expecting the possibility that it might be RPM related, but I'm sure I was over 6k at some point in time when I checked.

    Interested in seeing what the other minis are doing.
