2015-2016 BMW S1000RR (K46) Stage 1+ Performance Calibration

MAKE SURE TO REVIEW THE TABS ABOVE: HANDHELD, DYNO RESULTS, RESOURCES AND MORE INFO!

One of our most popular products yet, the feedback has been tremendous for over 13 years and has evolved into this final product. 

ADVANTAGES WITH OUR STAGE 1 FLASH:

• 9% power gain / 7% torque on pump fuel. Healthy Bikes on average gain  up to 10whp and 20whp on better fuels
• Much more aggressive and faster quickshifter
• Better cooling through lower fan adjustments
• Custom ignition timing and knock strategy for almost all fuels
• Conversion to "Alpha-N" fueling model, with modified fueling and lambda for best power and response
• Factory throttle limiters removed and flat spots and throttle response increased greatly 
• Engine braking modified in all modes
• Speed limits offand rev-limit raised for maximum performance
• Smoothing of the part throttle rideability and idle on and off the track without bucking and jerking found in factory tune
• Less aggressive ABS / DTC / Wheelie control and bike intervention for more experienced rider looking to shave seconds off their laps
• Reshaped torque model for more power at all RPM's part or full-throttle sooner for power

HOW WE ACCOMPLISH THIS WITH OUR FLASH

ALPHA-N FUELING – Alpha-N is a different type of fueling strategy used by motorsport racing teams and OEM manufacturers alike. It’s a means of tuning using a fuel look up table and throttle position. The advantages of Alpha-N are simple: more relative filing (power), accurate fueling at any throttle angle, razor sharp throttle response with lambda trimming and full ECU control, engine smoothness and of course, increased horsepower.

IGNITION – Optimized to make the most power while still being safe and reliable. We set the map up so that a single map will work on different octane fuels. The better the fuel, the more power the bike will make with no changes needed from the end user.

THROTTLE DERESTRICTION – Giving you the ability to utilize 100% of the throttle is paramount in track situations where you need all the power you can get on demand. The factory file has dead zones per gear that kills the bikes power curve when it should be making the most. This also means any kind of straight line acceleration also suffers. We remove these factory restrictions to ensure a smooth and predictable throttle, all the way to redline.

LOWER FAN-ON TEMP – Let’s face it, this bike rides a little on the hot side. To help not only the riders enjoyment but also keep the engine slightly cooler, we’ve lowered the fan-on temps. Cooler temps result in a more consistent and powerful motorcycle.

INCREASED RPM LIMITER (at customer request) – We raised the stock RPM limiter and after years of in-depth testing, we have found zero negative side effects. This helps you stay in the powerband longer and reduces the need to shift at the track.
