KTM EXC 150 TBI - FLAWLESS ECU Performance Flash
KTM EXC 150 TBI Tuning from 2024 – what the Performance Flash achieves
The FLAWLESS ECU Performance Flash replaces the stock software in the original ECU of your KTM EXC 150 TBI (2024 models and newer). The injection, power valve, and electronic oil pump maps are adjusted, resulting in a significant increase in power, noticeably higher torque, smoother throttle response, and better lubrication, all without the need for additional hardware on the motorcycle.
Unlike piggyback tuning modules, we modify the stock software directly. The optimization remains invisible from the outside, the ECU software number remains unchanged, and KTM diagnostic tools can still be used without restriction.
We write the software individually for your motorcycle and tune it to the hardware actually installed – to your exhaust system and, if applicable, to an aftermarket piston or cylinder head.

| Exhaust gas temperature | Stock level | in the optimal range |
| Power valve | Stock maps | adjusted |
| 2-stroke oil injection quantity | Stock electronic oil pump map | increased, significantly better lubrication |
| Additional hardware on the bike | – | not required |
Power increase for the KTM EXC 150 TBI
We write the tuning software individually for your KTM EXC 150 TBI and adjust it exactly to your installed hardware. This allows you to achieve a significant increase in power as well as noticeably higher torque.
Beyond pure power gains, we primarily improve rideability: the power delivery of your EXC 150 TBI becomes more homogeneous and smoother.
KTM does not provide an official power output for the EXC 150 TBI. Our statements therefore refer to the difference compared to the stock condition, measured on our dyno.
Smoother throttle response and no jerking in the partial load range
With our software optimization, we eliminate the annoying jerking in the partial load range of your EXC 150 TBI.
This provides you with a significantly smoother throttle response between idle and 50% throttle – exactly the range where you spend most of your time off-road.
Optimized injection, power valve, and AFR values for the KTM EXC 150 TBI
The injection and power valve maps are also adjusted by us. As a result, the air-fuel ratio (AFR) values and the exhaust gas temperature of your EXC 150 TBI remain in the optimal range.
This benefits not only performance but also the thermal load on your engine.
More 2-stroke oil through adjusted oil pump maps
Your EXC 150 TBI features an electronic oil pump. By adjusting its maps, we increase the injected 2-stroke oil quantity.
The result is significantly better lubrication for your engine – a point that counts especially for a two-stroke engine used for sports.
Individual tuning for your setup
Every software optimization for the KTM EXC 150 TBI is tuned to the specific setup of your motorcycle. Please provide the following information in the comment field at checkout when placing your order:
- installed exhaust system, e.g., Doma or FMF
- aftermarket piston installed: yes or no
- aftermarket cylinder head installed: yes or no
This allows us to optimally tune the mapping of your KTM EXC 150 TBI to your motorcycle.
How the software optimization for your KTM EXC 150 TBI works
- Configure – Order your FLAWLESS ECU Performance Flash and select the desired options.
- Send in the ECU – Remove the ECU from your KTM EXC 150 TBI and send it to us well-packaged and insured.
- Programming – Upon receipt, your ECU will generally be processed by our technicians within 24 hours. For shipments from Switzerland, the processing time is usually 24 to 72 hours.
- Install and ride – We will send your ECU back to you. Connect, install, done.
No additional hardware necessary
No additional control unit is installed on the motorcycle for this software optimization. Your original ECU is programmed by us. The control unit is not opened or damaged, and it remains unchanged from the outside.
The software number of your ECU remains unchanged, and KTM 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 mapping individually – we do not use purchased, pre-made files.
The foundation for this is created on our own high-performance simulation dyno. Every setup variant is individually installed and specifically tuned during development. Our maps are therefore based on real measured data and not on rules of thumb or copied files.
We process well over 1000 ECUs 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 fits your motorcycle and intended use.

Frequently Asked Questions about KTM EXC 150 TBI optimization
How much power does tuning the KTM EXC 150 TBI add?
You will receive a significant increase in power and noticeably higher torque. At least as noticeable are the more homogeneous power delivery, the eliminated partial load jerking, and the smoother throttle response.
Why is the stock power not listed in the table?
KTM does not provide an official power output for the EXC 150 TBI. Our statements therefore refer to the difference compared to the stock condition, measured on our dyno.
What changes in the throttle response?
We eliminate the jerking in the partial load range. The throttle response between idle and 50% throttle becomes significantly smoother – exactly the range where you spend the most time off-road.
What does the increased 2-stroke oil quantity do?
We increase the injected oil quantity via the electronic oil pump maps. This ensures significantly better lubrication for your engine.
Is the power valve also adjusted?
Yes. In addition to the injection maps, we also adjust the power valve maps for the EXC 150 TBI.
Is the software tuned to my exhaust system?
Yes. We take into account the installed exhaust system as well as any potentially different piston or cylinder head during the tuning process. Please provide these details in the comment field of your order.
Is the optimization suitable for all EXC 150 TBI models from 2024 onwards?
Yes. This software optimization is intended specifically for the KTM EXC 150 TBI model years 2024 and newer.
Can I continue to use a KTM tester?
Yes. KTM diagnostic tools continue to function without restriction because the ECU software number remains unchanged.
Does the ECU need to be opened for programming?
No. The ECU is not opened or damaged during programming. The optimization is not recognizable from the outside either.
How long does the processing take?
After your ECU is received, processing usually takes place within 24 hours. For shipments from Switzerland, the processing time is usually 24 to 72 hours.
Am I allowed to ride on public roads with the optimized software?
The software deviates from the stock condition. Usage is permitted exclusively on closed-off terrain or racetracks.
