I have a pair of the Nightrider XIED inline 02sensor Fuel Management sensors used for 6 months bfore upgrading o stage 3. They work great for a stock to stage 1. Price is 50.00 shipped.

Our simple plug-n-play fuel management upgrade that fits most 2007 and later Harley-Davidson motorcycles. Nightrider's unique patented design works inline with your existing 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 TC96/103/110 engine from the stock 14.6:1 to 13.8:1 AFR. The XiED's will add approximately 8% 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:
Cooler exhaust temperatures
Reduced engine temperatures
Improved throttle response
Less engine ping
Recommended for HD bikes with OEM emissions downloads. These include:
TC96, TC96 Stage 1
TC103, TC103 Stage 1, TC103 Stage 2
TC110, SE CVO 110
XL 883, XL 1200, XR1200, all XL Stage 1
Not for use on 09 Touring and 10/11 CVO Softail (use VIED)
The XIED works fine with Upgraded exhaust systems including slip-on mufflers and full exhaust changes, and air cleaner upgrades are compatible with the XiED(R) upgrade.

A major magazine tested the XIED's. The fuel ratio was richer than promised, registering at 13.7:1 AFR. Read that review here.
