Fuel Dongle PP-39




  • This kit is for delete and emulate the O2 sensor located on the exhaust manifold and correct the air/petrol 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.



  • 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 performance:

  • The engine control unit is configured to have an AFR (Air Fuel Ratio) that is too lean, exactly 14.7 to <5000 RPM y 20% de acelerador. Una vez el motor ha llegado a su temperatura de funcionamiento, los sensores O2 suministran información a la unidad motor y poder mantener la mezcla en 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 easy, follow the O2 sensor wires on 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.
