The Autotuner Tool keeps growing its motorcycle coverage. A new protocol adds full OBD Normal Read (NR) support for Keihin 812.41 and 796.41 ECUs, used on popular KTM, Husqvarna, GasGas and Husaberg off-road bikes.
You can now read and write these ECUs directly through the diagnostic connector, with no need to remove or open the ECU. From KTM SX-F and EXC-F to Husqvarna FC/FE and GasGas MC/EX models, that opens up more tuning work across motocross, enduro and off-road performance.
