The FuelX Pro is the advanced performance fuel injection optimizer specifically designed for the Yamaha R15 V3 BS6 (2020–2021). While the V3 is celebrated for its high-revving nature and Variable Valve Actuation (VVA), the BS6 emission constraints often lead to a lean fuel mixture, causing low-end jerkiness and increased engine heat during spirited riding.
The Pro version unlocks the engine’s potential by offering 10 switchable maps, providing the ability to fine-tune throttle response and optimize torque delivery for both city commuting and track-focused performance.
Key Features
-
10 Switchable Autotune Maps: Includes a handlebar-mounted switch to cycle through 10 fueling levels. Prioritize “Economy” (Levels 1–3) for fuel-efficient daily rides or “Performance” (Levels 7–9) for maximum torque and a crisper engine feel.
-
Handlebar Map Switch: A rugged, weatherproof, and backlit interface for instant control. Adjust your engine’s fueling personality on the fly without needing to stop or use external software.
-
Real-Time Autotuning: Regardless of the map selected, the unit constantly monitors engine load, altitude, and temperature to maintain the perfect Air-Fuel Ratio (AFR) for that specific setting.
-
Sharper Throttle Response: Eliminates the jerky “on-off” throttle transitions and low-end stutters found in stock BS6 tuning. This results in a more connected feel and smoother power delivery across the rev range.
-
Significant Heat Reduction: By correcting the lean factory fuel mixture, the FuelX Pro helps the 155cc liquid-cooled engine run up to 10% cooler, preserving engine health during high-RPM riding or heavy traffic.
-
Seamless VVA Performance: Provides a more linear power curve, ensuring a smoother transition when the Variable Valve Actuation (VVA) engages and eliminating “flat spots.”
-
Plug-and-Play Installation: Features a model-specific harness with OEM-spec connectors. No wire cutting or permanent modifications are required, making the installation 100% reversible.

Why Choose FuelX Pro for Your R15 V3?
-
Precision Tuning: The R15 V3 is a sharp tool; the Pro version provides the punchy mid-range torque needed to exit corners with more authority and achieve faster roll-on acceleration.
-
Ultimate Protection for Mods: If you have upgraded to a high-flow air filter or an aftermarket exhaust, the Pro is vital. It ensures the fueling matches the increased airflow, protecting your internal components from lean-running damage.
-
Versatile Riding Character: Keep the bike in a balanced mode for your daily commute and instantly switch to a high-performance map for a weekend track session or spirited highway run.
Installation Note
The main module is typically tucked under the pillion seat, while the waterproof map switch is clamped onto the handlebar for easy thumb access. Because it uses original factory connectors, the unit can be removed before service visits to keep the bike’s ECU history and warranty status intact.
