Husqvarna FE 501 2020 to 2023 - FLAWLESS ECU Performance Flash

More power and torque?
At FLAWLESS Industries, we offer you a software optimization for your Husqvarna FE 501 2020 to 2023 with our exclusive FLAWLESS ECU Performance Flash. This optimization of your ECU or control unit comes with features that will put you in the fast lane, all without additional hardware – simply by flashing your control unit.

• Power increase: We individually write and adapt the tuning software or optimization for your Husqvarna FE 501 to your installed hardware. This achieves an increase in power of approximately 3 to 4 HP and 4 to 6 Nm of torque, or 7 to 8 HP with our FLAWLESS Performance Kit. In addition to the power increase, our FLAWLESS ECU Performance Flash improves rideability: the power delivery of your FE 501 becomes significantly more homogeneous and smoother. The characteristics of your FE 501 between the two mappings are further spread, giving you an even softer ride in the soft mapping and an even sportier ride and characteristic in the sport mapping. We also adjust the injection maps so that the air-fuel ratio values of your FE 501 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.

• FLAWLESS Performance Kit: When developing our FLAWLESS Performance Kit for your Husqvarna FE 501, our main focus was always to create a product that allows you to get the maximum rideability and performance increase from your Husqvarna FE 501 with as little effort as possible.
We achieved this goal through our proprietary intake design in conjunction with an MWR Sport-Pilzluftfilters:

– With our FLAWLESS Performance Kit, we increase the peak power of your FE 501 by almost 7 to 8 HP. You also have a significantly longer power plateau, so the power is usable for much longer.
– Significantly more homogeneous power band across the entire rpm range – the riding experience is significantly enhanced, more powerful, and sportier.

In combination with our FLAWLESS ECU Performance Flash, you get the FLAWLESS Performance Kit for your FE 501 for only €120.00. The discount will be automatically deducted in the shopping cart.

• FLAWLESS Power Mapswitch: Full attack at the touch of a button? With this option, you can switch between 2 mappings on the handlebars of your Husqvarna FE 501, so you have the standard mapping (restricted) on Map 1 and the FLAWLESS ECU Performance Flash with all desired functions on Map 2! This allows you to switch between restricted and FLAWLESS ECU Performance Flash on-the-ride.

Please specify in the comment field at checkout which restricted power level you would like for Map 1. By default, we program a restricted power level of 18HP, which corresponds to the original factory restriction.

• FLAWLESS Quickshifter GP: With our exclusive FLAWLESS Quickshifter GP, we retrofit the quickshifter for your Husqvarna FE 501 2020 to 2023 – without an additional sensor – for even faster clutchless upshifts!
Due to our Custom Code in your control unit, you do not need an additional sensor. Our FLAWLESS Quickshifter GP works with the existing gear position sensor and uses the reference values of the sensor already learned in the control unit, so no manual reading and adjustment of the reference values is necessary.

Thanks to the closed-loop system of our code, the ignition is only reactivated when the gear change is completely finished. The special feature: the interruption times adapt adaptively to the respective shifting process. This effectively avoids the risk of premature ignition release, which can occur with systems with fixed interruption times, and ensures optimal performance with every shift.

• Pops and Bangs: Give your Husqvarna FE 501 the final acoustic touch. Through our optimization, we can configure the overrun cut-off individually according to your wishes and the installed setup of your Husqvarna FE 501 and, if desired, assign it to the respective riding modes.

• Hardcut Limiter: With the Hardcut Limiter, the standard rev limiter of your FE becomes a real race limiter, providing an unmistakable riding experience. Flames from the exhaust are guaranteed with the Hardcut Limiter!

Please state your setup in the comment field at checkout when ordering. It is important to specify which exhaust muffler (Akrapovic, FMF, ...), which header, and which air filter (K&N sport air filter, BMC, Rade Garage, ...) you have installed.

Process:
1. Order the FLAWLESS ECU Performance Flash or your ECU software optimization for your Husqvarna FE 501 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 receive it, we will individually adapt your FLAWLESS ECU Performance Flash. Usually, we send you your control unit with the modified software back within 24 hours so that you can reinstall it as quickly as possible.
Excessive use of the Hardcut Limiter can lead to engine damage.
To achieve the specified performance, it is necessary to use an accessory exhaust muffler (Akrapovic, FMF, etc.).
The control unit is not damaged or opened. The FLAWLESS ECU Performance Flash is not externally visible. Husqvarna testers function without restriction. The software number remains unchanged.

- Suitable for Husqvarna FE 501 models from 2020 to 2023
- Simple and fast service
- Maximum performance increase and improved handling
