Flex Update Bosch MD1 MG1 ECU Read Write via Boot

Magic Motorsport Flex users can now unlock locked Bosch MD1 MG1 ECUs directly using Boot mode, eliminating external RFT service dependencies for bench reading and writing.

Technical Overview

This protocol enables direct Boot mode unlocking on Bosch MDG1 Engine Control Units equipped with Tricore Aurix TC2xx microprocessors (TC298 / TC299). Performing this initial Boot unlock unlocks full, autonomous Bench read/write access. Subsequent operations do not require opening the ECU enclosure.
