Our simple plug-n-play fuel management upgrade specifically designed for 2007 and later H-D Sportster 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 XL883/XL1200/XR1200 engine from the stock 14.6:1 to 14.0:1 AFR. The X14iED's will add approximately 6% 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
- Less engine ping
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 X14iED(tm) upgrade.
