DO NOT WATCH the AFR lights WHILE THE BIKE IS IN MOTION Notes e Richer closed loop AFR values cannot be achieved if any exhaust leaks exist Even the smaller exhaust leak may cause less accuracy of the AF XIED or check engine lights Improper installation of slip on muffler or exhaust system upgrades may cause small leaks e AF XiED size is 2 5 L x0 9 W X 0 7 H e Settings between 14 3 4 to 13 9 8 tend to work best Because of the way that the O2 sensors AF XiED and ECM interact higher settings do not always result in the best results The settings are the approximate AFR based on an average bias values in the ECM The bias value is the centering voltage that the ECM uses to determine if it needs to make injector pulses longer or shorter based feedback It receives from the O2 sensor MEA VT NILES LAS Nightrider com Performance Products http sales nightrider com sales nightrider com Modern Engineering Old School Service S amp P MULLEN Enterprises Inc Oldsmar FL 34677 Please Note Transient codes P0131 and or P0151 may be present in the electronic control module ECM after the XIED is installed The presence of these specific codes in ECM history is not unusual on bikes with IEDs installed nor does their presence cause any problems The HD Service Manual indicates that these codes and be cleared and ignored No Check Engine light will occur Disclaimer This product is intended for race vehicles
