2015-2019 Yamaha R1 / R1M SFN Handheld Tuning Tool

Power Gains:

• Increase Peak Power by +30HP: Full optimization of the engine’s fuel and ignition systems to boost power without compromising reliability. This includes adjusting fuel mapping, air-fuel ratio (AFR), and ignition timing for maximum efficiency at peak RPM.

Throttle Response Optimization:

• De-restricted Throttle Limiter: Increase throttle response from 60% to 100% for faster, smoother power delivery.
• Throttle Mapping Adjustments: Fine-tuning throttle behavior to smooth out the on/off twitchiness typical of factory settings. This will make throttle response more linear and predictable, enhancing handling and track performance.

Fueling and Exhaust Adjustments:

• Optimized Fueling for Stock/Aftermarket Exhaust: Fine-tuned air-fuel ratio to match any exhaust system while providing smooth and efficient combustion at all throttle ranges.
• Safe Yet Aggressive Ignition Mapping: Adjusting ignition timing to maximize power while ensuring it stays within safe limits, protecting the engine.

RPM and Rev Limits:

• Increased RPM Limit to 14,700: If requested, the engine’s redline will be raised to 14,700 RPM for improved high-end power and responsiveness, with careful tuning to ensure engine longevity.

Cooling System Adjustments:

• Lower Cooling Fan Activation Temperature: Lower the fan activation from 216°F to 195°F to keep the engine cooler under high-performance conditions, ensuring consistent power delivery without overheating.

Quickshifter and Auto-Blipper Modifications:

• Adjustments for Lower and Higher RPM Use: Modify quickshifter settings to enhance shifting at low and high RPMs, ensuring smoother transitions on and off the throttle, especially useful for track riding or competitive racing.

Traction Control Tuning:

• Aggressive Traction Control Settings: Modifications to the traction control system, improving grip and allowing for faster lap times with more aggressive tires. This includes adjusting the TC for quick power delivery without sacrificing rear-end stability.

Launch Control Settings:

• Race-Ready Launch Control: Fine-tuning launch control to improve starts during racing conditions, ensuring smoother, more efficient acceleration off the line.

Top Speed Limiter Removed:

• Unlock the Full Potential: Removal of any electronic speed limiters to allow the vehicle to achieve maximum top speed based on its current power and aerodynamic capabilities.

Stage Legal Testing:

• Compliance with Stage Regulations: Testing and validation of modifications to ensure they comply with legal regulations for competition use, maintaining eligibility for stage-legal racing or street use (if required).
