BT Moto Performance Calibration With Handheld Tuner Stage 1 + for BMW S 1000 R 2021-24

What Is Stage 1?

Introducing our inaugural flash for the 2021+ BMW S1000R! Utilizing our decade of experience and research into the BMW ECU's has helped us A LOT to develop the 2021 Single R Stage 1 Flash. US and European model S1000R’s have been restricted from the factory, with the US models having some of the worst restrictions we have ever seen on a BMW liter bike short of the 2017+ BMW K1600.

What's Being Restricted?

• Throttle Restriction - Throttle is restricted and has a lazy feel on tip-in riding along with loss of power in certain gears / RPM's
• Exhaust Valve - Restricted to keep quieter, which results in power loss
• RPM Limiter - The stock RPM limiter is set to 12,000 RPM and cuts the powerband off too soon
• Fueling - The 2021+ BMW S1000R fueling is set rich from the factory and needs adjustment
• Heat Management - The S1000R feels hot and runs hot

What Do We Do To Fix These Issues?

• Throttle Restriction - We remove the throttle restrictions across the board to give you the riding experience and power you wanted from the factory
• Exhaust Valve - We still utilize the stock exhaust valve to give you maximum power but also open it up when you need to make peak power gains
• RPM Limiter - We moved the limiter from the stock 12,000RPM to 12,500RPM to maximize your powerband
• Fueling - We program the S1000R to target a better AFR (Air/Fuel Ratio) to make a little more power along with fixing drivability and idle issues
• Heat management - We turn the fans on early and adjust the fueling to a proper ratio to make for a cooler running, more consistent bike.

Benefits

• 8% horsepower gain across the RPM range (see graph below)Horsepower gained from exhaust valve management
• Cooler riding temps
• Startup strategy issues solved. Idle is smooth and consistent
• Improved throttle response in all gears
• Longer powerband from increased RPM limiter
