Program via the diagnostic port: just carry out the Virtual Read, make your modifications like increasing power or removing DTCs, then write the file directly on the control unit.

In order to work in OBD, you need the FLX2.68 cable compatible with the newest EU5 and EU5+ motorcycles from brands such as Ducati, Honda, Suzuki, KTM, Harley, Yamaha, Aprilia, Kawasaki 6pin.

TECHNICAL NOTE: Please note that versions before 7.40.0.0 might not work correctly due to a server update. We recommend to keep the software up to date.
