Fuel Dongle PP-69

Description

• This kit allows remove the oxygen sensor or lambda probe from the exhaust.

• Oxygen sensors or lambda probes installed in the exhaust limit engine performance since its function is to control gas emissions.

• Due to the pollution regulations, the stoichiometric mixture (AFR) is raises in a certain RPM range, causing the engine to go poor gasoline.

• An engine with a lean mixture will be unstable, will jerk, overheat and have a noticeable loss of performance.
  

Advantages

• Elimination jerking, rattling and instability at low RPM.
  
• Improvement the engine response at low and medium RPM.
• Reduce exhaust and engine temperature.
  
• Establishes a correct AFR for engine operation.
• Plug & Play.

Additional Information:

• Does not increase fuel consumption.
• Does not appear engine failure.
• Compatible with and without catalytic converter exhausts.
• Connectors OEM sealed.
• All our products are designed for use in competition and/or on closed circuits.

Functioning

• The engine control unit (ECU) is configured to have an AFR (Air Fuel Ratio) too lean, exactly 14.7 at <5000 RPM and 20% throttle.

• Once the engine has reached its operating temperature, O2 sensors supply information to the engine unit and can maintain the mixture at 14.7.

• Because of this, it occurs an increase in engine and exhaust system temperatures, coupled with jerking and rattling noises while driving.

• By putting one of our FuelDongle A signal is sent to the control unit to lower the mixture one point and set the AFR to 13.8. This means that "we enrich" the mix and it is translated in better performance of the motorcycle.
