Lambda Probe Eliminator for Harley-Davidson Dynojet Oxygen Sensor Eliminator

Lambda Probe Eliminator for Harley-Davidson Dynojet Oxygen Sensor Eliminator 76423011

The 2006 Dyna® models and all models from 2007 to present with electronic fuel injection are equipped with two narrow-band oxygen sensors (Lambda probes) and the Delphi® control unit that works with these sensors to obtain information on the operation during the "closed loop" and adjust the Air-Fuel mixture to meet emissions regulations.

When the engine reaches operating temperature, the motorcycle's ECM will maintain the Air-Fuel Ratio at 14.6 during idle and also at half throttle. While riding in these "closed-loop" conditions, most aftermarket ECMs are unable to modify this mixture (AFR) and add fuel (necessary if the exhaust or filter has been replaced, for example). The ECM will correct any attempt to change it in this way, so the solution is to install these O2 sensor eliminators by simply plugging them into the Lambda probe connector.

These eliminators have internal electronics that simulate a "cold sensor" situation and allow the injection to operate in "open loop" at all times, allowing the aftermarket ECU to gain full control of the EFI injection in all situations and conveniently modify the entire AFR map. It will therefore be able to make changes across the entire engine operating range, from idle to wide open throttle.

• Sold individually.
• For all 2006 and later Harley-Davidson® models with 2-wire Lambda sensor.
