*At the current moment, all S58s are flashable over OBD, including the latest 2020-03 dealer update.

**EEPROM area holds security keys, error memory, performance statistics and other vital infomation that is used by dealers during diagnostic. We have unique ways that allow us to be the only company on the market to offer our clients a full backup of the un-modified EEPROM area over OBD2 port. This data is stored on our servers and can be used by us to flash it back to the computer on the bench at our facility. The customer can also request this data to be transfered to them if they prefer to use their own shop of choice to have this data written back in.
