Our simple plug-n-play fuel management upgrade specifically designed for the 2006 H-D Dyna motorcycles. Nightrider's unique patented design works inline with the H-D Bosch narrow band O2 sensor and Delphi ECM to richen the fuel mixtures. Riders can quickly and simply richen the closed loop fuel mixture on your TC88/95 engine from the stock 14.6:1 to 14.3:1 AFR. The DYN OiED's will add approximately 3% more fuel to the engine in closed loop operating mode than a similar unequipped vehicle. There is an indirect richening of open loop fuel mixture's through the learning mode or adaptive fuel value action, ensuring these richer 13.8-12.5:1 AFR's are also adjusted in heavy/full throttle situations.
This richer fuel mixture results in benefits that can include:
Less low speed engine surge
Cooler exhaust temperatures
Reduced engine temperatures
Improved throttle response
Recommended for HD bikes with OEM emissions downloads. These include
Upgraded exhaust systems including slip-on mufflers and full exhaust changes, and air cleaner upgrades are compatible with the DYN OiED upgrade.
Some 2006 Dyna's with exhaust upgrades and DYN OiED's are know to exhibit transient CE lights under two specific conditions. On long, off throttle decel, the CEL might come on. On extended idle, the CEL might come on. In both cases, the CEL goes off as you accelerate away from a stop. The only historic codes seen in the ECM should be P0131/P0151. These codes would be 'normal'. Any other codes should be investigated and are not associated with the DYN OiED's.
