Fits all R1150 models, R1100S (S Models only), R1200C and all K1200RS & LT bikes.
The AF-XiED O2 sensor manipulator is a plug and play O2 sensor controller that allows you to change the closed loop fuel injection air/fuel ratio from the stock overly lean 14.7:1 ratio (the main culprit in surging and poor throttle response issues) to as low as 13.6:1. It is a simple plug and play device that plugs in between your stock O2 sensor and the bikes wire harness and is easily adjusted with a small screw driver. Advanced circuitry changes the O2 signal sent to the stock BMW Motronic fuel injection brain to achieve a richer air fuel ratio. Benefits include elimination of surging, much better throttle response and acceleration, better pull from low rpms in all gears, the ability to ride a gear higher than normal and reduced pinging. This is a much simpler, more elegant and less expensive solution than piggy-back fuel controllers like the Power Commander to the notorious lean running condition on the BMW R1150 bikes. The BMW-AF-XiED allows the full use of the Motronic and leverages its adaptive abilities to also richen open loop air/fuel ratios. After a couple tank-fulls of gas your bikes Motronic will have full adapted and the bike will be running better and better. We have tested this device back to back with a dyno tuned Power Commander on one of our personal bikes and came away so impressed we sold the Power Commander and started carrying the product - it is that good!
Fits all R1150 models, all R1200C & CL models, K1200RS & LT bikes and also the R1100S model (R1100S only - will not fit any other R1100 bike).
