BMW Handheld Tuner with Custom Mapping

No need to send in your ECU or remove it from your bike at all. You order the handheld, it gets delivered to you, you flash your bike. You never miss a day of riding and no effort removing the ECU.

The best new motorcycle on the market! US and European model S1000RR's have been restricted from the factory with the US models having worse restrictions than its European counterpart. Stage 1 was developed to remove these restrictions and unlock your S1000RR’s full potential, the difference on the 2023 is the most astonishing out of any BMW to date - a must have.

What's Included In Stage 1?:

• De-restricted Throttle +60hp gains in the midrange, and +20whp over the curve!
• De-restricted Exhaust Valve and intake flappers, open to 100% in certain riding scenarios for best sound and performance
• Throttle response increased 12% in every race pro 1-3 mode to reach a target of 100% throttle. Road mode de-sensitized for highway cruise, normally jerky
• Cruise control jerkiness adjusted for highway cruising tip in and out.
• Torque limiter of 75% raise to 100% free top end horsepower, 200whp on a stock bike. (a BT Moto exclusive!) 170mph limiter (due to torque) removed will go 190mph GPS on stock sprockets on stock limiter. Viewable in our review video.
• Better Fuelling, cleaned up for maximum fuelling economy and horsepower gains
• Second and third gear transmission limiter removed
• Enhanced and restructured hard cut rev-limiter
• Mapping available for different modification combos
• Heat Management through better fuelling, and lower cooling fan strategy
• A second and a half off your 60-130!

How Do We Accomplish This With Stage 1?

THROTTLE RESTRICTION / TORQUE / GEAR LIMITATIONS- 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 spots" that may cause the S1000RR to behave in an unpredictable manner when corner exiting. This also means any kind of straight line acceleration also suffers. We remove these factory restrictions to ensure a smooth and predicable throttle, all the way to redline. It's like getting a new engine, all over again! On the 2023 its very difficult to do this. Only BT Moto has figured out how to "fully" de-restrict the 2023, through torque limits to achieve max power and 100%. The competition still is getting limited. With the torque limiter in place the bike is slower then the 2010 BMW S1000RR!

EXHAUST VALVE / INTAKE FLAP- The exhaust valve is a double edged sword. It does good by making back pressure when needed but also hinders the 2023 S1000RR from making the most power possible at mid to upper RPM ranges. The valve closed makes the bike a lot more quiet than if it were open, even slip-on exhaust sounds almost the same as stock due to this valve closing so much. Opening this valve for racing use allows for some horsepower gains, as they are gear and RPM dependent, just like the butterfly valves for the throttle. Lower gears have a smaller valve opening which will reduce overall volume and power by 3-5HP, even in lower RPM’s. Our mapping still utilizes the stock exhaust valve to give you maximum power but also opens it up when you need it most.

FUELLING - The 2023 BMW S1000RR fuelling is rich for worldwide environment (desert) and longevity purposes but it's overkill. It is also set artificially lean at idle, cruise, and warm up, which results in stalling and cold/hot start issues. The new S1000RR is factory equipped with 5-wire widebands (just like the 2020+ S1000RR) and is very precise on targeting a specific AFR (Air/Fuel Ratio) through a closed loop corrective system from idle to redline. Being factory rich also helps it cool the turtleshell exhaust system. However, fuel can be trimmed for better result as it targets real time fuel corrections.

HEAT MANAGEMENT - Lets face it, this bike rides a little on the hot side. Due to the new exhaust system and idle/cruise AFR mixtures the bike is a recipe to being constantly in the 215+F range and burning your legs while you ride, making it uncomfortable anywhere you’re not going 50+MPH. We have solved this issue by adding our low fan temp modification to this flash as a standard baseline feature along with different cruise mapping which has curbed temps extensively.

Second Gear Pull

Red = Stock flash with 91 Pump Gas
Blue = Stage 1 flash with 91 Pump Gas

This graph shows stock vs flashed on 91 pump gas, same day. This was done in 2nd gear to show power differences and restrictions are the worst for the stock mapping in 2nd gear. There's a gain of over 60WHP in the mid-range and more power up top as well.

Fifth Gear Pull

Red = Stock flash with 91 Pump Gas
Blue = Stage 1 flash with 91 Pump Gas

This graph shows stock vs flashed on 91 pump gas, same day. This was done in 5th gear to show power differences and how much restriction the stock 2023 S1000RR mapping has. The gains are all across the RPM range and the bike even gains 10WTQ. The higher redline is achieved as well. These are the LARGEST BMW gains on the RR to date, don't sleep on the product or settle for less with a competitor.

**Testing performed with California ACN 91 octane pump gas. Usage of a lower octane will yield smaller power gains. Higher octane larger gains**

• US 91 = UK 95 RON
