KTM RC 390 2017 to 2021 - FLAWLESS ECU Performance Flash

More power and torque?
We at FLAWLESS Industries offer you a software optimization of your ECU or control unit for your KTM RC 390 from 2017 to 2021 with our exclusive FLAWLESS ECU Performance Flash, featuring functions that will put you in the fast lane. And all this without additional hardware - just by flashing your control unit.

• Performance increase: We write the tuning software or optimization individually for your KTM RC 390 and adapt it to your installed hardware. This achieves an additional output of approx. 4 to 5 hp and 3 to 6 NM of torque. In addition to the increased performance, our FLAWLESS ECU Performance Flash improves drivability: The power delivery of your RC 390 becomes significantly more homogeneous and smoother. The annoying constant throttle jerking of your KTM also completely disappears after the control unit optimization, giving you a significant increase in drivability. In addition, our performance 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 RC 390 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 RC 390 the final acoustic touch. With our optimization, we can configure the overrun fuel cut-off individually according to your wishes and the installed setup of your KTM RC 390. Important - with a configuration including a catalytic converter, only exhaust burbling is possible.

You can customize the optimization or mapping directly when ordering according to your wishes. The selection fields are available for this purpose.
Please state in the comment field at checkout when ordering which setup you are running. It is important to specify which rear silencer (LeoVince, Remus, Austin Racing, Arrow, Akrapovic, ...) and which air filter (K&N sports air filter, BMC, Rade Garage, ...) you have, as well as whether you have a catalytic converter installed.

Procedure:
1. Order the FLAWLESS ECU Performance Flash or your ECU software optimization for your KTM RC 390 with the desired options.
2. Send your control unit or ECU well packaged to us (FLAWLESS Industries - Pilatusring 20, 91353 Hausen, Germany).
3. We 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 have received it, we will individually adapt 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 stated 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 restrictions. The software number remains unchanged.
