How it works

Flash your GOES 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 GOES ATV?

GOES quads are built for work and for trails, but their Bosch calibration is written for emission tests: lean at small throttle openings, with a soft response at low speed, where an ATV spends most of its time. A reflash smooths the throttle, corrects the fuelling for an exhaust or intake change and lets you set limits for your use.

GOES ECU families

  • Bosch MSE6.0: the Cobalt 550, Copper 300, Iron 400, Terrox 400S and 500L EPS, and XWolf 700.
  • Bosch MED17: the Terrox 1000 (2025 onwards).

Both are read and written through the diagnostic connector with a Tactrix OpenPort 2.0 or CANable.

Flashing a GOES, step by step

  1. Keep the battery on a charger.
  2. Connect a Tactrix OpenPort 2.0 or CANable to the diagnostic connector.
  3. Read the ECU and save the original file.
  4. Edit the maps or load the file from your tuner.
  5. Write it back. MotoFlasher corrects the checksum.
