KTM 790 DUKE 2023 to 2024 - FLAWLESS ECU Performance Flash

KTM 790 Duke EURO 5 Tuning 2023 to 2024 – what the Performance Flash achieves

The FLAWLESS ECU Performance Flash replaces the stock software in the original ECU of the KTM 790 Duke for model years 2023 to 2024. Fuel injection, ignition, lambda control, and throttle response curves are adjusted – resulting in approximately +12 hp more power, +15 Nm more torque, an eliminated torque dip, and significantly smoother power delivery, with no additional hardware required 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 ECU software number does not change, and KTM diagnostic tools can continue to be used without restriction.

We tailor each software individually to your motorcycle and the hardware actually installed. It can be combined with the FLAWLESS Power Mapswitch, our optimized FLAWLESS quickshifter, Linear Throttle, a lowered fan temperature, and an individually configured fuel cut-off for pops & bangs.

KTM 790 Duke EURO 5: Stock vs. optimized software compared

Performance increase for the KTM 790 Duke

We write the tuning software individually for your KTM 790 Duke and adapt the maps to the hardware installed on your motorcycle.

Depending on the setup, we achieve an increase in performance of approx. +12 hp as well as around +15 Nm of torque.

The well-known torque dip of your KTM at approx. 4,500 rpm disappears thanks to our ECU optimization.

In addition to the pure increase in power, we primarily improve the power delivery. The 790 Duke accelerates more smoothly and consistently and reacts more directly to throttle inputs overall.

The annoying constant throttle jerkiness of your KTM is also completely gone after the ECU optimization – giving you a significant plus in rideability.

Higher rev limiter for A2 restriction

If you ride your 790 Duke in the A2-restricted version, the rev limiter is lowered from the factory. As part of the optimization, we raise it to 10,000 rpm – the same value as the original A version.

This gives you access to the full rev range and allows the 790 Duke to rev out freely again.

Optimized injection and AFR values of the KTM 790 Duke

As part of the KTM 790 Duke ECU tuning, we also adjust the injection maps. This ensures that the Air-Fuel Ratio (AFR) values of your 790 Duke are in an optimal range for your specific setup.

In addition to improved rideability, this also achieves thermal relief for the exhaust valves and cylinder heads, as exhaust gas temperatures decrease due to the adjusted mixture preparation.

FLAWLESS Power Mapswitch for the KTM 790 Duke

Full attack at the push of a button? With the FLAWLESS Power Mapswitch, you can activate and deactivate the Performance Flash via the riding modes of your 790 Duke. You can switch between the original software and the full FLAWLESS ECU Performance Flash at any time – without having to stop or make mechanical changes.

• Stock A – original unrestricted power
• Stock A2 – restricted power for the A2 license

We will coordinate with you at the time of order which configuration should be assigned to which riding mode.

FLAWLESS Quickshifter for the KTM 790 Duke

We developed our quickshift algorithm from scratch. It gives your 790 Duke a noticeably faster shifting speed and a sportier feel.

For this, we not only refined the interruption times but overhauled the entire quickshifter algorithm. The result is faster and cleaner gear changes across the entire rev range.

Linear Throttle for the KTM 790 Duke

Not satisfied with the current throttle response? Upon request, we can program your throttle curve 1:1 to the throttle valve position. In this setting, 50% throttle grip position corresponds exactly to 50% throttle valve position.

This gives you a significantly more direct and better-metered throttle response from your KTM 790 Duke.

Lowered fan temperature for the KTM 790 Duke

It's not just you who wants to keep a cool head. We lower both the switch-on and switch-off temperatures of the fans by approx. 4 °C.

This ensures your 790 Duke stays reliably within the optimal temperature range even during very spirited riding and in city traffic.

Pops & Bangs and overrun burbles on the KTM 790 Duke

Give your KTM 790 Duke the final acoustic polish. We configure the fuel cut-off individually according to your wishes and matched to the installed setup – from subtle burbles to distinctly audible exhaust pops.

On request, we can also program the pops only for certain riding modes of your 790 Duke. That way, you have them exactly when you want them.

Important: If your setup includes a catalytic converter, only overrun burbles are possible. Please indicate when ordering whether your 790 Duke has a cat installed, and we will adjust the configuration accordingly.

Individual tuning for your setup

Every software optimization for the KTM 790 Duke is tuned to the installed setup of your motorcycle. You can configure the optimization or mapping directly when ordering via the selection fields. Please also provide the following information in the comments field at checkout:

• Installed rear silencer or exhaust system, e.g., LeoVince, Remus, Austin Racing, Arrow, or Akrapovic
• Installed air filter, e.g., K&N, BMC, or Rade Garage
• Catalytic converter present: yes or no
• Other relevant modifications

This allows us to optimally tune the mapping of your KTM 790 Duke to your motorcycle.

Suitable Performance Parts for your KTM 790 Duke

The exhaust system and air filter have a particular influence on optimal map tuning. You can find suitable parts in the following categories:

• Exhaust systems from Akrapovic, LeoVince, and MIVV
• Sport air filters from K&N and MWR; BMC or Rade Garage are also suitable

Systems from Remus, Austin Racing, or Arrow are also suitable. We are happy to clarify which combination works best for your setup before you order.

What hardware is required for maximum performance?

To achieve the stated performance increase on the 790 Duke, the following are strictly required:

• An accessory rear silencer or sport exhaust, e.g., from LeoVince, Remus, Austin Racing, Arrow, or Akrapovic
• A sport air filter, e.g., from K&N, BMC, or Rade Garage

Without these components, the specified power gains cannot be fully realized. The other functions of the optimization – rideability, AFR values, Power Mapswitch, quickshifter, Linear Throttle, fan temperature, and fuel cut-off – are available to you regardless.

How the software optimization of your KTM 790 Duke works

1. Configure – Order your FLAWLESS ECU Performance Flash and select the desired options.
2. Send in ECU – Remove the ECU from your KTM 790 Duke and send it to us, well-packed and insured.
3. Programming – Upon receipt, your ECU is usually processed by our technicians within 24 hours. For shipments from Switzerland, the processing time is usually 24 to 72 hours.
4. Install and ride – We send your ECU back to you. Connect, install, done.

No additional hardware necessary

No additional control unit is installed on the motorcycle for the software optimization. We program your original ECU. The control unit is not opened or damaged during this process and 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 map individually – we do not use purchased, ready-made files.

The basis for this is created on our own high-performance simulation test bench. Every setup variant – from the stock configuration to the combination of various sport exhaust systems, sport air filters, and configurations with and without a catalytic converter – is installed and specifically tuned there during development. Our maps are therefore based on real measurement data and not on rules of thumb or inherited files.

We process well over 1,000 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 which configuration suits your motorcycle and intended use.

Frequently asked questions about KTM 790 Duke optimization

How much power does the KTM 790 Duke tuning provide?

Depending on the installed hardware, we achieve approx. +12 hp and +15 Nm more torque. At least as noticeable are the eliminated torque dip at approx. 4,500 rpm, the more consistent power delivery, and the eliminated constant throttle jerkiness.

What happens to the rev limiter if my KTM is restricted to A2?

We raise it to 10,000 rpm, which is the value of the original A version. This gives you access to the entire rev range again.

How does the FLAWLESS Power Mapswitch work?

You activate or deactivate the Performance Flash via the riding modes of your 790 Duke. You can switch between the original software and the optimization at any time. We will coordinate with you at the time of order which configuration is mapped to which riding mode.

What does the FLAWLESS Quickshifter achieve?

We developed the quickshift algorithm from the ground up and refined the interruption times. The result is faster and cleaner gear changes across the entire rev range of your 790 Duke.

What does Linear Throttle do?

It sets the throttle grip curve 1:1 to the throttle valve position. 50% throttle grip means exactly 50% throttle valve opening, which makes the response more direct and easier to meter.

Why is the fan temperature lowered?

We lower the switch-on and switch-off points of the fans by approx. 4 °C. This helps your 790 Duke stay more reliably in the optimal temperature window even during very spirited riding.

Do I need a sport exhaust or sport air filter for the optimization?

For the specified power increase, yes – an accessory rear silencer and a sport air filter are required for the 790 Duke. The other functions of the optimization are available to you even with stock hardware.

Does the optimization also work with a catalytic converter?

Yes. The performance increase and optimized injection maps are also possible with a catalytic converter. However, with a catalytic converter, only overrun burbles are possible for the fuel cut-off, not aggressive exhaust pops.

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 the tuning process. Please provide this information in the comment field of your order.

Can I continue to use a KTM tester?

Yes. KTM 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?

After we receive your ECU, the processing is usually completed within 24 hours. For shipments from Switzerland, the processing time is typically 24 to 72 hours.

Is the optimization suitable for all 790 Duke models from 2023 to 2024?

Yes. This software optimization is specifically designed for the KTM 790 Duke model years 2023 to 2024 with EURO 5.

Can I ride with the optimized software on public roads?

The software deviates from the stock configuration. Use is permitted exclusively on closed circuits or race tracks.
