    ETC rate limit

    This is under torque management under the engine section. It is next to ETC limit. Stock the values are .10, so do higher values make the response much quicker or zeroing it out make the throttle response quicker? values are from 0-100 %

    thank you so much for replying. I have disabled the ETC limit but it doesn't work, the throttle response is still so slow, nothing like a cable throttle body. I have noticed that when i max out the tip in torque limit with the etc limit disabled, the throttle response increases a little bit, but i suspect that the ETC rate limit has something to do with slow response... all im lookin for is if 100 increases response or 0 increases response

    100% opens fast.

    You may also have burst knock retard making it feel like there's no response.

    Log the actual pedal position versus the actual throttle plate position, you'll be able to see the throttle plate response. If there's no delay there, the problem probably lies in spark retard, either burst knock, or torque management, or running on a low octane table...or all of the above.

    My "Desired Pedal Area" is 100 at the top three cells. Should I change anything here? I'm looking for better throttle response.
    There is a strong warning that you may render the PCM permanently inoperable! What's up with that. Image attached.2013-10-27 19_12_25-.jpg
