This kit including 2 sensor eliminator and come with EXHAUST BUNG CAP.
Instruction: Why you need oxygen sensor eliminators modification?
1. After disabling O2 sensors, you will gain a vastly improved throttle response and smoother power delivery because your bike have more torque available in this specific situations,and stopping the Powercommand & FI2000R fighting with your bike ECM.
2. After bypass faulty oxygen sensor you can use any brand after markdet exhaust system. Most US exhaust is without O2 sensor mount, so this is only way to bypass it without FI problems.
3. The oxygen sensor eliminator is also needed to support the FI mods like the Power Commander and it can help all the FI mods to complete.
4. Stock design is O2 sensors of the motorcycles are limited to catch the emission standards and best A/F ratio for environmental and air pollution. This is good for the emissions but not for the performance and smoothness of the engine.
After you mod air kit or muffler, you will find popping and back fire. That is air/fuel ratio change and stock ECM can not balance, so all the bike shop or your rider mate told you that you got mod Power commander or Cobra FI2000R. But the O2 sensor still research and respond the air/fuel that too rich or lean for ECM and ECM send this signal tnozzle, then PC3/5 FI2000 intercept this signal, mod it and send it out to nozzle. After engine ignited, O2 sensor check it and told ECM that mod it to be original. This cycle is nonstop. O2 sensor and your mod PC3 or 5, Cobra FI2000 is always in anti and fighting.
Easy to install, you only need to unplug the wires from the oxygen sensor to the wiring harness until you find its connector, then you disconnect it and you connect the eliminator in Main wire harness side.
For the motorcycles that have two oxygen sensors, our eliminator kits have two eliminators, you use the procedure above for each oxygen sensor plug and remove the O2 sensor. Then tighten cap in sensor mount holes.
