Honda Fireblade, Africa Twin and Hornet: new OBD access
Autotuner now supports Honda Euro 5 motorcycles with Keihin RH850 through the diagnostic port. This simplifies access to the engine software.
Support released on October 21, 2026 includes the Honda CBR1000RR-R Fireblade, Africa Twin 1100, CB750 Hornet and X-ADV 750 with a suitable Keihin RH850 ECU. Access uses OBD Normal Read: the existing data is actually read, rather than merely retrieving an original file from a database.
Autotuner lists the bootloader, software and calibration as the read scope, along with checksum correction. Stated times are about ten minutes for reading and three minutes 15 seconds for writing. The six-pin Euro 5 motorcycle cable linked by the manufacturer, part ATOBD080, is required. Support is released and is not marked as beta.
