KTM 690 Enduro from 2026 EURO 5 Plus – FLAWLESS ECU Performance Flash

More power and torque?
At FLAWLESS Industries, we offer you software optimization of your ECU or control unit for your KTM 690 Enduro 2026 EURO 5 Plus with our exclusive FLAWLESS ECU Performance Flash, with features that let you ride in the fast lane. And all without additional hardware – just by flashing your ECU.

We can also offer you the so-called Full Mapswich for the Euro 5 Plus models! With our Full Mapswich, you can now not only set the linear throttle to a mapping or driving modes, but also the complete FLAWLESS ECU Performance Flash – including all options such as lambda control, throttle cut-off, shift pops and, of course, the performance boost.

– Performance increase: We write the tuning software or optimization individually for your KTM 690 SMC-R and adapt it to your installed hardware. As a result, we achieve an increase in power of approx. 2.5 to 3.5 hp at peak and 20 to 23 NM more torque at approx. 4500 RPM. In addition to the extra power, our FLAWLESS ECU Performance Flash also improves rideability: the power delivery of your 690 Enduro becomes significantly more homogeneous and consistent. The annoying constant jerking of your KTM has also completely disappeared after the ECU optimization, giving you a significant increase in rideability. In addition, the well-known torque bend of your KTM at approx. 4500 rpm disappears thanks to our performance increase. We also adjust the injection maps so that the air-fuel ratio values of your 690 Enduro are now in the optimum range. This also reduces the thermal load on the exhaust valves and cylinder heads due to the resulting lower exhaust gas temperatures.

– FLAWLESS Power Mapswitch: Full attack at the touch of a button? With this option, you can switch between the mappings on the handlebars of your KTM 690 Enduro, so that you have the standard mapping on one riding mode and the FLAWLESS ECU Performance Flash with all the desired functions available on the other riding mode!

– FLAWLESS Quickshifter: Discover our newly developed FLAWLESS Quickshift algorithm, which gives your 690 Enduro unparalleled shifting speed and sportiness! We have not only refined the interruption times, but also optimized the entire quickshifter algorithm to give you the ultimate quickshifter experience. For an even more intense driving experience, we offer optional shift acoustics in Track and Sport driving modes, which give every gear change an impressive soundscape – perfect for anyone looking for the ultimate in sportiness! Important – gearshift acoustics are not possible in a configuration with a catalytic converter.

– Hardcut Limiter: The Hardcut Limiter turns the standard rev limiter on your Enduro into a genuine racing limiter that ensures an unmistakable riding experience. With the Hardcut Limiter, flames from the exhaust are guaranteed!

Important: The Hardcut Limiter may only be used in conjunction with an exhaust system without catalytic converter and without DB-Killer. Please note that increased engine wear cannot be ruled out with excessive use.

– Optimized fan temperature: Your engine stays cooler! We lower the fan switch-on temperature from 100°C to 95°C – for earlier cooling, more thermal stability and less thermal stress on your engine.

– Linear throttle: The previous throttle response is not good enough for you? On request, we can program your throttle response curve 1 to 1 with the throttle valve response curve – 50% throttle means 50% throttle valve position. For the ultimate response behavior of your KTM 690 Enduro

– Pops and bangs: Give your KTM 690 Enduro the final acoustic touches. Thanks to our optimization, we can configure the throttle cut-off individually according to your wishes and the installed setup of your KTM 690 Enduro and, if desired, also set it to the respective riding modes. Important – in a setup with a catalytic converter, only a thrust bump is possible.

You can adjust the optimization or mapping directly when ordering according to your wishes. The selection fields are available for this purpose.
When ordering, please indicate which setup you are using in the comments field at the checkout. It is important which rear silencer (LeoVince, Remus, Austin Racing, Arrow, Akrapovic, …), which air filter (MWR sports air filter, BMC, Rade Garage, …) and air filter cover (open air filter / Powerparts cover, perforated cover, …) and whether you have installed a catalytic converter.

Procedure:
1. Order the FLAWLESS ECU Performance Flash or your ECU software optimization for your KTM 690 Enduro with the desired options.
2. Send your control unit or ECU well packaged to us (FLAWLESS Industries – Pilatusring 20, 91353 Hausen, Germany)
3. We will process the software of your ECU on the day it arrives and usually send it back to you within 24 hours.
4. Unpack, connect and drive off.

Important
In order to be able to offer you this service, it is necessary for you to send us your removed control unit from your vehicle. As soon as we have received it, we will customize your FLAWLESS ECU Performance Flash. We usually send your ECU back to you with the modified software within 24 hours so that you can reinstall it as quickly as possible.
To achieve the specified performance, it is necessary to use an accessory rear silencer (LeoVince, Remus, Austin Racing, Arrow, Akrapovic, etc.), a sports air filter (K&N sports air filter, BMC, Rade Garage, etc.) and the Powerparts air filter cover or perforated cover. The upgrade air filter we offer is a K&N sports air filter. The ECU will not be damaged or opened. The FLAWLESS ECU Performance Flash is not visible from the outside. KTM testers function without restriction. The software number remains unchanged.

– Suitable for KTM 690 Enduro models from model year 2026 (EURO 5 Plus)
– Simple and fast service
– Maximum performance increase and improved handling
