They work inline with the smaller H-D Delphi heated narrow band 02 sensors and Delphi ECM to richen the fuel mixtures, adding 6% more fuel to the engine in closed loop mode. There is an indirect richening of the open loop fuel mixtures through the learning mode, or adaptive fuel value action built into your ECM. This ensures the richer 13.8-12.5:1 AFR's are ALSO adjusted in heavy/full throttle operation.
