Husqvarna FE 501 2024 to 2025 – FLAWLESS ECU Performance Flash

More power and torque?
At FLAWLESS Industries, we offer you software optimization of your ECU or control unit for your Husqvarna FE 501 2024 to 2025 with our exclusive FLAWLESS ECU Performance Flash, with features that will put you in the fast lane. And all this without any additional hardware – just by flashing your ECU.

– Performance increase: We write the tuning software or optimization individually for your Husqvarna FE 501 and adapt it to your installed hardware. As a result, we achieve an increase in power of approx. 3 to 4 hp and 4 to 6 NM torque or 7 to 8 hp with our FLAWLESS Performance Kit. In addition to the extra power, our FLAWLESS ECU Performance Flash also improves the driveability: the power delivery of your FE 501 becomes significantly more homogeneous and even: the characteristics of your FE 501 between the two mappings are spread even further, so that you have an even softer driveability and characteristics in the soft mapping and an even sportier driveability and characteristics 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 optimum range. This also reduces the thermal load on 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, the focus was always on developing a product that allows you to get the maximum rideability and performance increase out of your Husqvarna FE 501 with the least possible effort.
Our own design of an intake in conjunction with a K&N Sport mushroom air filter has enabled us to achieve this goal:

– 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 that the power can be used for much longer.
– Significantly more homogeneous power band across the entire rev range – the riding experience is significantly enhanced, more powerful and sportier.

– 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 that you have the standard mapping (throttled) on Map 1 and FLAWLESS ECU Performance Flash with all the desired functions available on Map 2! So you can switch on-the-ride between throttled and FLAWLESS ECU Performance Flash.

Please indicate in the comment field at checkout which throttled performance level you would like on Map 1. By default, we program a throttled power level of 18 hp, which corresponds to the original series throttling.

– FLAWLESS Quickshifter GP: With our exclusive FLAWLESS Quickshifter GP, the quickshifter on your Husqvarna FE 501 works as it should – without an additional sensor – for more precise upshifts without a clutch!
Thanks to our custom code in your control unit, the quickshifter now works much more efficiently and also from 1st gear. Our FLAWLESS Quickshifter GP works with the existing gear position sensor and uses the reference values of the sensor already taught into the control unit, so that 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 complete. The special feature here is that the interruption times adapt to the respective shifting process. This effectively avoids the risk of premature ignition release, which can occur in systems with fixed interruption times, and ensures optimum performance with every gear change.

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

When ordering, please indicate which setup you ride in the comments field at checkout. It is important which rear silencer (Akrapovic, FMF, …), which manifold and which air filter (K&N sports air filter, BMC, Rade Garage, …) you have installed.

Procedure:
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 packed 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 (Akrapovic, FMF, etc.).
The control unit will not be damaged or opened. The FLAWLESS ECU Performance Flash is not visible from the outside. Husqvarna testers function without restriction. The software number remains unchanged.

– Suitable for Husqvarna FE 501 models from 2024 to 2025
– Easy and fast service
– Maximum performance increase and improved handling
