How it works

Flash your Kove in four steps

  1. 01

    Connect

    Plug your interface into the diagnostic port, or wire the ECU on the bench with the diagram from your account.

  2. 02

    Read & back up

    MotoFlasher identifies the ECU and reads the full flash. Keep that original file: it is your way back.

  3. 03

    Tune

    Edit fuel, ignition, limiters and the other maps in your tuning editor, or load a file from your tuner.

  4. 04

    Write

    MotoFlasher corrects the checksum and writes the file back. Start the bike and ride.

Why flash a Kove ECU?

Kove makes some of the most capable rally and adventure bikes in their class, and riders push them hard. Their factory maps are written for emission tests and a wide range of markets, so they run lean at part throttle and keep the response soft. A reflash lets you set fuelling and response for your exhaust, your altitude and the terrain you ride.

Kove ECU families

  • Bosch MSE8.0: the 450 Rally.
