Change VIN on ECU

Post by usbbdm »

If you find the VIN change does not boot the ECU, you are likely need to change the checksum of the VIN number. I have found one and after change the checksum, it works.
You need to disassemble the firmware and know exactly where and how to calculate the checksum. This is quite time consuming but doable.
