What’s Included in Our M109R ECU Flash

Our Suzuki M109R ECU flash goes far beyond a basic tune. Each calibration is designed to optimize how your engine delivers power, throttle response, and overall rideability.

• IAP Fuel Maps: Optimized for improved low-throttle fueling and smoother cruising performance
• TPS Fuel Maps: Adjusted for better throttle response and acceleration under load
• Ignition Timing Maps: Refined for increased power and more efficient combustion
• Secondary Throttle Plate (STP) Maps: Reworked to improve throttle control and eliminate factory restrictions
• O2 Sensor Disable: Eliminates factory closed-loop restrictions for consistent fueling

Every M109R ECU tune is designed to work seamlessly with stock or modified setups, including aftermarket exhaust systems and high flow air filters.
