Wheel circumference must always be calibrated using an OEM CAN protocol


When we calibrate the wheel speeds from an OEM vehicle (to make an OEM CAN Protocol), we always use the stock wheel sizes, so to get correct wheel speeds within MaxxECU, you must calibrate your wheel dimensions, since they are used to show you the correct speed in MaxxECU.
