    Laggy throttle fixed but dead spot in pedal now?

    So I fixed laggy throttle and it's amazing. But now to fix problem number two. At 60% pedal it seems as though it's telling the throttle body I want 100% throttle. Above 60% it's just dead space in the pedal and I was getting pedal position codes at the track. Any ideas? Thank you

    pedal creates a torque request

    torque request obtains the required map, spark, etc to realize the torque value requested by the pedal

    map required dictates throttle blade opening

    something like that

    so basically, pedal and throttle are not as related as they once were back in the good ol days

    I was hoping you would chime in. Your other post helped a ton. Any idea where I should start looking to get rid of this dead space? The car was throwing p0121 throttle/pedal position sensor A circuit range/performance
