BMW S1000RR K67 2021 to 2022 - FLAWLESS ECU Performance Flash
BMW S1000RR K67 EURO 5 Tuning 2021 to 2022 – what the Performance Flash achieves
The FLAWLESS ECU Performance Flash replaces the stock software in the original engine control unit of the BMW S1000RR K67, model years 2021 to 2022. Adjustments are made to injection, ignition, lambda control, and throttle response curves – this results in approximately 8 hp more power, 7 Nm more torque, and a noticeably more homogeneous power delivery, without any additional hardware on the motorcycle.
Unlike piggyback modules or auxiliary control units, we intervene directly in the stock software. The optimization remains invisible from the outside, the software number of the ECU does not change, and BMW Motorrad diagnostic tools can continue to be used without restriction.
We tune every piece of software individually to your motorcycle and the hardware actually installed. Upon request, it can be combined with a gear-dependent permanently open exhaust flap, Linear Throttle, lowered fan temperatures, and an individually configured fuel cut-off for "Pops & Bangs."

Performance upgrade for the BMW S1000RR K67
We write the tuning software individually for your BMW S1000RR K67 and adapt the maps to the hardware installed on your motorcycle.
Depending on the setup, we achieve an increase in power of approx. +8 hp and around +7 Nm of torque.
Beyond just raw power, we primarily improve power delivery. The S1000RR accelerates more homogeneously and smoothly and responds more directly to throttle inputs overall.
The typical constant-throttle jerk of the S1000RR is also significantly reduced or eliminated by the optimized maps.
Optimized injection and AFR values of the BMW S1000RR K67
As part of the BMW S1000RR ECU tuning, we also adjust the injection maps. This ensures that the Air-Fuel Ratio (AFR) values of your S1000RR K67 are in a range optimized for your specific setup.
In addition to improved rideability, this can also reduce thermal stress. Adjusted mixture preparation leads to lower exhaust gas temperatures, which particularly relieves thermal load on exhaust valves and cylinder heads.
Exhaust flap control of the BMW S1000RR K67
Do you want to hear more from your BMW S1000RR K67? Upon request, we will keep the exhaust flap permanently open.
We program the flap control to be gear-dependent: As soon as a gear is engaged on your S1000RR, the exhaust flap remains permanently open. This way, you don't just feel the extra power—you hear it, too.
Linear Throttle for the BMW S1000RR K67
Do you want a more direct and better-controllable throttle response? Upon request, we program a linear throttle curve. This means, for example, that 50% throttle grip position corresponds exactly to 50% throttle plate position.
This gives you a significantly more direct and predictable response from your BMW S1000RR K67.
Optimizing the fan temperature of the BMW S1000RR K67
Upon request, we lower both the switch-on and switch-off temperatures of the fans by approx. 4 °C each.
This allows active cooling to start earlier and run longer. Your S1000RR will remain more reliably within the optimal temperature range even during very sporty riding, high ambient temperatures, or in city traffic.
Pops & Bangs and overrun burbles on the BMW S1000RR K67
We adjust the fuel cut-off of your BMW S1000RR K67 individually to your wishes and your installed setup—from subtle overrun burbles to clearly audible pops and bangs.
Important: With a setup including a catalytic converter, only overrun burbles are possible. Please specify in your order if a cat is installed on your S1000RR so we can adjust the configuration accordingly.
Individual tuning for your setup
Every software optimization for the BMW S1000RR K67 is tuned to the installed setup of your motorcycle. Please include the following information in the comments field of your order:
- Installed rear silencer or exhaust system, e.g., Akrapovic, SC-Project, or Austin Racing
- Installed air filter, e.g., K&N, BMC, or DNA
- Catalytic converter present: yes or no
- Other relevant modifications
This allows us to optimally tune the mapping of your BMW S1000RR K67 to your motorcycle.
Matching performance parts for your BMW S1000RR K67
Exhaust systems and air filters, in particular, influence optimal mapping. You can find matching parts in the following categories:
- Exhaust systems from Akrapovic, LeoVince, and MIVV
- Sports air filters from K&N and MWR; BMC or DNA are also suitable
Systems from SC-Project or Austin Racing are also suitable. We are happy to clarify which combination is best for your setup before you place your order.
What hardware is required for maximum performance?
To achieve the stated performance increase on the S1000RR K67, the following are mandatory:
- An aftermarket rear silencer or sports exhaust, e.g., from Akrapovic, SC-Project, or Austin Racing
- A sports air filter, e.g., from K&N, BMC, or DNA
Without these components, the specified performance increase cannot be fully realized. The other features of the optimization—rideability, AFR values, exhaust flap, Linear Throttle, fan temperature, and fuel cut-off—remain available to you regardless.

No additional hardware necessary
No additional control unit is installed on the motorcycle for the software optimization. Your stock ECU is programmed by us. The control unit is not opened or damaged in the process and remains unchanged from the outside.
The software number of your ECU remains unchanged, and BMW Motorrad diagnostic tools can continue to be used without restriction.
Why FLAWLESS Industries?
We have been developing our software optimizations in-house for over 5 years and write every map individually—we do not use purchased off-the-shelf files.
The foundation for this is created on our own high-performance simulation dyno. Every setup variant—from the stock configuration to combinations of various sports exhaust systems, sports air filters, and configurations with or without catalytic converters—is individually installed and specifically tuned during development. Our maps are therefore based on real measured values rather than empirical estimates or copied files.
We process well over 1000 control units annually. Development and programming take place entirely in Germany. If you have questions about your setup, you can reach us directly—we will advise you before you order on which configuration suits your motorcycle and intended use.

Frequently asked questions about BMW S1000RR K67 optimization
How much power does tuning the BMW S1000RR K67 provide?
Depending on the installed hardware, we achieve approx. +8 hp and +7 Nm more torque. Just as noticeable is the smoother power delivery and the eliminated constant-throttle jerk.
Can the exhaust flap be kept permanently open?
Yes. We program the flap control to be gear-dependent: As soon as a gear is engaged, the exhaust flap of your S1000RR K67 remains permanently open.
What does the Linear Throttle achieve?
It sets the throttle grip curve 1:1 to the throttle plate position. 50% throttle grip therefore means exactly 50% throttle plate position, which makes the response more direct and better to modulate.
Why is the fan temperature lowered?
We lower the fan switch-on and switch-off temperatures by approx. 4 °C each. Active cooling therefore begins earlier and runs longer, which thermally relieves the engine during sporty riding and high ambient temperatures.
Do I need a sports exhaust or sports air filter for the optimization?
For the stated performance increase, yes—an aftermarket rear silencer and a sports air filter are required for the S1000RR K67. The other functions of the optimization are also available to you with stock hardware.
Does the optimization work with a catalytic converter?
Yes. The performance increase and optimized injection maps are also possible with a catalytic converter. However, for the fuel cut-off, only overrun burbles can be generated with a cat, not "pops and bangs."
Is the software tuned to my exhaust system?
Yes. We take into account the installed rear silencer, air filter, catalytic converter, and other relevant modifications during tuning. Please provide these details in the comments field of your order.
Can I continue to use a BMW Motorrad tester?
Yes. BMW Motorrad diagnostic tools continue to function without restriction, as the software number of the ECU remains unchanged.
Does the control unit need to be opened for programming?
No. The ECU is not opened or damaged during programming. The optimization is also not detectable from the outside.
How long does the processing take?
Following receipt of your ECU, processing is generally carried out within 24 hours. For shipments from Switzerland, the processing time is usually 24 to 72 hours.
Is the optimization suitable for all K67 models 2021 to 2022?
Yes. This software optimization is specifically intended for the BMW S1000RR K67 of model years 2021 to 2022 with EURO 5.
