    2019 Jeep JLU speedometer calibration?

    Can I calibrate my speedometer with HP tuners?

    Yes. On the JKU it can actually be done through the scanner without using any credits

    Yes. It is available in VCM Scanner, just like the JKU. You can also adjust other things such as gear ratio, transfer case ratio, TPMS, etc.

    Is a smart access cable and modified pcm required to change tire size through the vcm scanner for 2018+ JL/JLU? Or can this be done with just the smart access cable?

    I went ahead and picked up a smart access cable and was able to recal for larger tire size through the vcmscanner… no modified pcm required.
