The FuelX Pro+ is the premium performance fuel injection optimizer specifically engineered for the Royal Enfield Hunter 350 (2022–2024). While the Hunter 350 is known for its agile, urban-centric personality, its J-Series engine is factory-tuned to run “lean” to meet strict BS6.2/OBD2 emission standards.
The Pro+ version unlocks the Hunter’s true potential by offering 10 switchable maps, allowing you to sharpen the throttle response, increase mid-range torque, and keep the engine running cooler during aggressive city sprints or highway cruises.
Key Features
-
10 Switchable Autotune Maps: Comes with a handlebar-mounted, backlit switch that lets you cycle through 10 fueling profiles. You can choose “Economy” settings (Levels 1–3) for fuel-sipping commutes or “Performance” settings (Levels 7–9) for maximum torque and engine cooling.
-
Handlebar Map Switch: A rugged, weatherproof interface that provides instant control over your engine’s personality. Change your ride feel on the fly without needing a laptop or stopping the bike.
-
Real-Time Autotuning: Regardless of the map you select, the unit intelligently monitors engine load, ambient temperature, and altitude to maintain the perfect Air-Fuel Ratio (AFR) for that specific setting.
-
Sharper Acceleration: The Hunter is designed for quick maneuvers. The Pro+ enhances this by providing a crisper throttle response and eliminating the low-end “flat spots” found in the stock tuning, resulting in faster roll-on acceleration.
-
Significant Heat Reduction: Lean fueling causes high engine temperatures. The FuelX Pro+ helps the 349cc engine run up to 10% cooler, which is vital for maintaining performance during heavy traffic or long summer rides.
-
Smoother Low-Speed Manners: It eliminates the jerky “on-off” throttle transition often felt at low speeds, making the Hunter 350 even more refined and easier to handle in dense urban environments.
-
Plug-and-Play Installation: Features a model-specific harness with OEM-spec connectors. No wire cutting or splicing is required, ensuring the installation is 100% reversible.

Why Choose FuelX Pro+ for Your Hunter 350?
-
Urban Agility: The Hunter is a street-fighter by design. The Pro+ amplifies this by providing the punchy mid-range torque needed to “dart” through traffic and exit corners with more authority.
-
The Perfect “Mod” Partner: If you have installed a free-flow exhaust or a high-performance air filter, the Pro+ is essential. It prevents the engine from running dangerously lean, protecting your valves and spark plugs from overheating.
-
Adaptive Riding: Switch to a high-performance mode for a weekend canyon run, and then toggle back to a balanced mode for your Monday morning commute—all with a single button press.
Installation Note
The FuelX Pro+ module is typically tucked behind the side panels or under the seat, while the waterproof map switch is mounted near the left handlebar grip for easy access. Since it uses factory-original connectors, the unit can be removed before service visits to ensure the motorcycle’s ECU history and warranty remain undisturbed.
