Can I calibrate my speedometer with HP tuners?
Can I calibrate my speedometer with HP tuners?
Yes. On the JKU it can actually be done through the scanner without using any credits
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.
