Bootloader mode for Supercars with New Flex Protocol for McLaren

Discover the new FLEX exclusive, version 7.25.0.0, and work on TCUs and CCUs of McLaren supercars like 570GT and 720S in Bootloader mode.

Work on the TCU by uploading optimized maps and customizing gear shifting logics on track or road, and access the CCU dedicated to semi-active hydraulic suspension management to adjust shock absorbers’ response, chassis balance, and dynamic stiffness.

Our new protocol is made to read and write the full Flash memory (with emulated EEPROM) of the MPC5554 microprocessor, all in just a few minutes.

Some of the supported vehicles:

• McLaren 540C 3.8L V8 BiTurbo 540PS
• McLaren 620R 3.8L V8 BiTurbo 620PS
