Find your ECU "Box Code" (Software Version)

What is the box code? When we refer to the box code of your vehicle, this is essentially the part number for the software on your vehicle; it is also often paired with a revision number. There are numerous ways in which you can find this code out yourself, doing so will allow us 100% confirm support your vehicle and will allow us to prepare the tune files ahead of time.
