With FLEX version 8.30.0.0, you can now work on Keihin K-line ECUs equipped with M16C processors, used in Honda, KTM, Husqvarna and GASGAS motocross bikes manufactured between 2013 and 2025.

Honda ECUs, usually located under the seat, can be accessed via a Pinout connection, while KTM, Husqvarna and GASGAS ECUs from the BMAG group support both OBD and Bench connections. With these connection methods, you can read Flash and EEPROM memory directly and access the data needed for further modifications and programming.
