The FuelX Pro is the advanced performance fuel injection optimizer specifically designed for the Royal Enfield Hunter 350 (2022–2024). While the Hunter is built for agile urban handling, its J-Series engine is factory-tuned to run “lean” for emission compliance.
The Pro version enhances the Hunter’s “urban-scrambler” character by offering 10 switchable maps, allowing you to sharpen throttle response and torque delivery for a more aggressive or refined ride.
Key Features
-
10 Switchable Autotune Maps: Includes a handlebar-mounted switch that allows you to cycle through 10 fueling levels. You can prioritize “Economy” (Levels 1–3) for fuel-efficient city riding or “Performance” (Levels 7–9) for maximum torque and cooler engine temperatures.
-
Handlebar Map Switch: A rugged, weatherproof interface that provides instant control over your engine’s fueling personality. Adjust the ride feel on the fly without needing to stop or use external software.
-
Real-Time Autotuning: Regardless of the map selected, the unit intelligently monitors engine load, altitude, and temperature to maintain the perfect Air-Fuel Ratio (AFR) for that specific setting.
-
Sharper Throttle Response: The Pro version provides a crisper, more connected feel between the throttle and the rear wheel, eliminating the low-end “flat spots” found in the stock factory tuning.
-
Significant Heat Reduction: Lean fueling causes air-oil cooled engines to run hot in traffic. The FuelX Pro helps the 349cc engine run up to 10% cooler, preserving engine health and increasing rider comfort.
-
Smoother Low-Speed Manners: It eliminates the jerky “on-off” throttle transitions often felt at low speeds, making the Hunter 350 even more agile and refined during dense urban maneuvers.
-
Plug-and-Play Installation: Features a model-specific harness with OEM-spec connectors. No wire cutting or splicing is required, making the installation 100% reversible.

Why Choose FuelX Pro for Your Hunter 350?
-
Tailored City Performance: The Hunter is designed for the urban jungle. The Pro version provides the punchy mid-range torque needed for quick overtakes and effortless filtering through traffic.
-
Essential for Modifications: If you have installed a performance air filter or a free-flow exhaust, the Pro is vital. It ensures your engine receives the correct amount of fuel to match the increased airflow, protecting your internal components.
-
Versatile Character: Keep the bike in a balanced mode for your daily commute and instantly switch to a high-performance map for a weekend canyon run or spirited ride.
Installation Note
The main module is typically tucked behind the side panels or under the seat, while the waterproof map switch is clamped onto the handlebar for easy thumb access. Because it uses original factory connectors, you can easily remove the unit before a scheduled service visit to ensure the bike’s ECU history and warranty remain untouched.
