How it works

Flash your Italjet 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 an Italjet Dragster?

The Dragster is a sport scooter with a chassis that asks for more than the stock calibration gives. Its factory map is written for emission tests: lean at small throttle openings and soft off the line. A reflash sharpens the response, corrects the fuelling after an exhaust change and lets the engine rev the way it was built to.

Italjet ECU

The 2022-onwards Dragster uses a Marelli MIU G4 ECU, the same family Piaggio uses in its scooters. It is read and written through the diagnostic connector with a Tactrix OpenPort 2.0 or CANable, without removing the ECU.

Flashing a Dragster, 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.

The same ECU is found in the Vespa, Beverly and MP3.
