14-15 HARLEY XL883N: Cobra FI2000R O2 Digital Fuel Processor Closed Loop Current motorcycle engines utilizing oxygen sensors and closed loop technology have very lean air/fuel mixture settings from the factory. These settings can limit power and make the engines run hotter than earlier model-year units. The Fi2000R O2 digital fuel processor is designed to work with all exhaust systems (stock or aftermarket) equipped with oxygen sensors in place. It accurately adjusts the fuel-injected engine&#39;s air/fuel ratio in order for it to run properly. Best of all it works much like a carburetor jet kit with adjustments similar to the air-mixture screw, the needle and clip positions and the main jet.Designed to work with all exhaust systems equipped with oxygen sensors in place (closed-loop design).Work
