KTM 390 DUKE 2017 to 2021 - FLAWLESS ECU Performance Flash

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

• Power Increase: We individually write the tuning software or optimization for your KTM 390 DUKE and adapt it to your installed hardware. This achieves an additional power of approx. 4 to 5 HP and 3 to 6 NM of torque. In addition to the increased power, our FLAWLESS ECU Performance Flash improves rideability: the power delivery of your 390 DUKE becomes significantly more homogeneous and smoother. The annoying constant speed surging of your KTM also completely disappears after the control unit optimization, giving you a significant improvement in rideability. Furthermore, our power increase eliminates the well-known torque dip of your KTM at approx. 4500 rpm. We also adjust the injection maps so that the air-fuel ratio values of your 390 DUKE are now in the optimal range. This also achieves thermal relief for 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 fine-tuning. With our optimization, we can configure the deceleration fuel cut-off individually according to your wishes and the installed setup of your KTM 390 DUKE. Important - with a catalytic converter configuration, only a deceleration rumble is possible.

You can adjust the optimization or mapping directly during the order process according to your wishes. The selection fields are available for this purpose.
Please specify the setup you are running in the comment box at checkout when ordering. It is important to specify which slip-on muffler (LeoVince, Remus, Austin Racing, Arrow, Akrapovic, ...) and which air filter (K&N sports air filter, BMC, Rade Garage, ...) you have, and whether you have a catalytic converter installed.

Process:
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 control unit on the day of arrival and usually send it back to you within 24 hours.
4. Unpack, connect and ride.

Important
To offer you this service, it is necessary that you send us your removed control unit from your vehicle. As soon as we receive it, we will customize your FLAWLESS ECU Performance Flash. We usually send your control unit with the modified software back to you 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 slip-on muffler (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.
