Fi2000

Fi2000 has built a strong reputation by delivering practical, rider-focused EFI tuning solutions for Harley-Davidson motorcycles. Modern Harley engines are often calibrated lean from the factory to meet emissions standards, which can lead to hesitation, excessive heat and poor throttle response, especially after intake or exhaust upgrades. Fi2000 fuel tuning modules are engineered to correct air fuel ratios across key RPM ranges, helping engines run cooler, smoother and more efficiently while restoring strong, predictable throttle response.

Advanced Fi2000R and PowrPro tuning modules use self-adjusting technology to automatically fine-tune fueling based on real-time riding conditions. Designed specifically for Touring, Trike, Dyna, Softail, Sportster and V-Rod platforms, these systems feature true plug-and-play installation with no dyno time, laptop connection or complex programming required. This makes Fi2000 an ideal solution for riders who want measurable performance improvements without the complexity of full ECU reflashing.

Fi2000 also supports EFI optimization with fuel processors and oxygen sensor-related solutions that stabilize closed-loop operation and eliminate lean surging at low speeds. These components integrate seamlessly with stock ECUs to improve drivability, reduce engine heat and enhance overall ride quality. Whether correcting fueling after exhaust upgrades or optimizing a daily rider or touring bike, Fi2000 fuel management systems deliver consistent performance, reliability and confidence mile after mile.
