What Is Stage 1?

Introducing our inaugural flash for the 2020+ BMW S1000XR! Utilizing our decade of experience and research into the BMW ECU’s has helped us A LOT to develop the 2020 XR Stage 1 Flash. US and European model S1000RR’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 for noise and makes a loss in power
• RPM Limiter – The stock RPM limiter is set to 12,000 RPM and cuts the powerband off too soon
• Fueling – The 2020 BMW S1000XR fueling is set rich from the factory and needs adjustment
• Heat Management – The S1000XR 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 and the sound you want
• RPM Limiter – We moved the limiter from the stock 12,000RPM to 12,500RPM to maximize your powerband
• Fueling – We program the S1000XR to target a better AFR (Air/Fuel Ratio) to make a little more power along with fixing drivability and idle issues

Benefits

• 8% horsepower gain across the RPM range (see graph below)Horsepower gained from exhaust valve management
• Cooler riding temps
• Potential cold start, hot start issues solved. Idle is smooth and consistent
• Improved throttle response in all gears
• Longer powerband from increased RPM limiter
• Better exhaust note (as bike is silent stock due to exhaust valve)

Dyno Graphs, Flashed vs Stock

The graph below represents dyno testing performed at a completely independent source.  We wanted to show that test results not only come from BrenTuning Moto but also can be seen on any dyno.

These tests were performed on a 100% stock S1000XR.  No exhaust, no air filter, nothing.  All tests were performed on 91 octane pump (testing conducted in Las Vegas).  All testing was done back to back.  No playing with temperatures or SAE to STD gains, etc.  You can see the gains are across the entire powerband for torque and horsepower.  8% gain in overall power is great for a simple ECU flash.

Stock – (RED) 150whp / 76wtq
BrenTuning Stage 1 – (BLUE) 158whp / 80whp

**WHP and WTQ means the power the motorcycle is putting to the ground.  Manufacturers use HP and TQ and this refers to the power being outputted by the engine only and is not a true reading of power.  After the engine of the motorcycle outputs its power it has to travel through the transmission chain, etc before it gets to the ground.  Because of this drivetrain loss, the wheel horsepower number is always less than the manufacturer claimed horsepower.
