    Speedometer calibration after tire size change

    How do you calibrate the speedometer after a tire size change? Since I updated to the latest version of HP tuners, the speedometer section has changed and there's no place to enter tire size. This is a P01 ECM from a 2001 Chevy. I have done it before, but now it's not there, or moved.

    Edit > gear tire wizard.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    It's there in the latest software for all of the Chevy P01 applications.

    He sig says he owns a ford, so very likely it's different on those computers.
