Updating, also known as flashing, vehicle ECU's remotely, while possible is not recommended.

There are many risks associated with flashing remotely, primarily the conneciton dropping during the writing of bootloader firmware - usually leaving the ECU bricked and no longer able to communicate with tooling.

If you choose to flash remotely using Car Connector, we take zero responsibility if the flash fails. By using Car Connector we, Car Connector limited, are absolved of any liabilty.
