Fuel Dongle PP-49 — FuelDongle.es®

Fuel Dongle PP-49




  • Dongle designed for motorcycles with regulations Euro 5. Due to pollution regulations, the stoichiometric mixture (AFR) is reduced in a certain RPM range, causing the engine to run lean on gasoline. A lean-burn engine will be unstable, jerk, overheat, and have a noticeable loss in performance.



  • Elimination of jerks, rattles and instabilities at low RPM.
  • Improves engine response at low and medium RPM.
  • Reduced exhaust and engine temperature.
  • Sets the ideal AFR for engine operation.
  • Plug & Play.

Additional information:

  • Does not increase fuel consumption.
  • No engine fault appears.
  • Compatible with exhausts with and without catalyst.
  • Required when removing catalytic converter.
  • Mandatory when installing external switchboards.
  • Sealed OEM connectors.
  • This dongle is sandwiched between the probe and the connector.
  • All our products are designed for use in competition and/or on closed circuits.


Technical operation:

  • The engine control unit is configured to have an AFR (Air Fuel Ratio) too poor, exactly 14.7 to <5000 RPM and 20% throttle. Once the engine has reached its operating temperature, the O2 sensors provide information to the motor unit and be able to keep the mixture at 14.7.
  • Due to this, there is an increase in the temperature of the engine, of the exhaust system added to jerks and rattles during the march.
  • Putting in one of our dongles sends a signal to the command unit to lower the mix one point and set the AFR at 13.8. All this translates into a better performance of the bike.




Compatibility with the following models:

    • Hypermotard 950 /SP > 2021 - 2023
