Vehicle Identification Number (VIN Broadcast on the CAN)


1. Enable the OBD-II protocol




2. Enter your VIN in the input box, make sure to enter all 17 characters. After you have entered your VIN, you can now safely disable the CAN OBD-II output protocol...

Note: Fail to enter the correct code above, will result in DTCs on device on your vehicle CAN.



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.
