Fuel Dongle PP-29




  • This kit is used to eliminate and emulate the O2 sensor located in the exhaust manifold and correct the air/fuel mixture.
  • Today's engines are designed to meet very strict emission regulations. To do this, they reduce the stoichiometric mixture (AFR) in a certain RPM range, making the engine run lean on gasoline. A lean-burn engine will be unstable, jerk, overheat, and have a noticeable loss in performance.
  • *This model of FuelDongle may momentarily illuminate the check engine light, then disappear.



  • 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.
  • All our products are designed for use in competition and/or on closed circuits.


    Technical operation:

    • The ECU is set to have too lean AFR (Air Fuel Ratio), exactly 14.7 at <5000 RPM and 20% throttle. Once the engine has reached its operating temperature, the O2 sensors provide information to the engine unit and be able to maintain 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.
    • Plugging in one of our dongles sends a signal to the control unit to lower the mix one notch and set the AFR to 13.8. All this translates into a better operation of the motorcycle.



    • Installation is simple, just follow the wires from the O2 sensor into the exhaust manifold. You will find a connector, unplug it and put the fuel dongle. Optionally you can remove the O2 probe and put the cap with the copper gasket.
