KTM 390 DUKE 2017 to 2021 – FLAWLESS ECU Performance Flash

More power and torque?
With our exclusive FLAWLESS ECU Performance Flash, we at FLAWLESS Industries offer you software optimization of your ECU or control unit for your KTM 390 DUKE 2017 to 2021 with features that will put you in the fast lane. And all without additional hardware – just by flashing your ECU.

– Performance increase: We write the tuning software or optimization individually for your KTM 390 DUKE and adapt it to your installed hardware. As a result, we achieve an increase in performance of approx. 4 to 5 hp and 3 to 6 NM torque. In addition to the extra power, our FLAWLESS ECU Performance Flash also improves rideability: the power delivery of your 390 DUKE 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 390 DUKE 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.

– Pops and bangs: Give your KTM 390 DUKE the final acoustic polish. Thanks to our optimization, we can configure the throttle cut-off individually according to your wishes and the installed setup of your KTM 390 DUKE. Important – in a configuration with a catalytic converter, only a thrust cut-off 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, …) and which air filter (K&N sports air filter, BMC, Rade Garage, …) as well as whether you have installed a catalytic converter.

Procedure:
1. Order the FLAWLESS ECU Performance Flash or your ECU software optimization for your KTM 390 DUKE 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.) and a sports air filter (K&N sports air filter, BMC, Rade Garage, etc.). The control unit 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.
