The Fi2000R O2 digital fuel processor is designed to work with all H-D exhaust systems (stock or aftermarket) equipped with oxygen sensors in place (closed-loop design)
Works much like a carburetor jet kit with adjustments similar to the air-mixture screw, the needle and clip positions and the main jet
The Fi2000R increases horsepower and torque by optimizing stock lean air/fuel mixtures (helps cool the engine temps as well)
Quick and simple installation with plug-and-ride technology with OEM-style connectors
No confusing computer downloads to install
No expensive dyno-testing required
Pre-configured from the factory for your make and model, but easy to adjust should your specific application need it
