Yamaha YZF-R9 from 2025 - FLAWLESS ECU Performance Flash

More power and torque?
We at FLAWLESS Industries offer you a software optimization of your ECU with our exclusive FLAWLESS ECU Performance Flash for your Yamaha YZF-R9 EURO 5 Plus from 2025, with features that will put you in the fast lane. And all this without additional hardware – just by flashing your control unit.

• Power increase: We individually write the tuning software or optimization for your Yamaha YZF-R9 from 2025 and adapt it to your installed hardware. This results in an additional power of approx. 4-7 HP and 5-7 NM of torque. In addition to the increased power, our FLAWLESS ECU Performance Flash also improves drivability: the power delivery of your YZF-R9 becomes significantly more homogeneous and smoother. The annoying constant speed surging of your Yamaha also completely disappears after the ECU optimization, giving you a significant increase in drivability. Furthermore, our performance upgrade eliminates the well-known torque dip of your Yamaha. The injection maps are adjusted by us so that the air-fuel ratio values of your YZF-R9 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. The torque limitation in certain gears is removed. This ensures that maximum torque is always available.

• 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 Yamaha YZF-R9, so that in PWR Mode 1, the restricted A2 power is active, and in PWR Mode 2, the FLAWLESS ECU Performance Flash with the unrestricted power level!

• Fan temperature: You're not the only one who wants to keep a cool head? By adjusting the fan temperature, your YZF-R9 always stays within the optimal temperature window, even with a very sporty driving style, as we lower both the switch-on and switch-off temperature of the fans by approx. 4 degrees.

• Deceleration fuel cut-off: Give your Yamaha YZF-R9 the final acoustic refinement. With our optimization, we can deactivate the deceleration fuel cut-off and thus activate pops & bangs on your YZF-R9. Important – with a configuration with a catalytic converter, only a deceleration gurgle is possible.

• Top-Speed Limiter: If you select this option, we remove the top speed limitations in the ECU.

• Immobilizer: Are you riding your YZF-R9 on the racetrack? Then we can deactivate the immobilizer so that you can start your motorcycle even without an ignition lock.

• Nice to know: We program your ECU so that lambda control is active and the series mapping is active in neutral gear. As soon as you engage 1st gear, our Performance Flash is active.

You can customize the optimization or mapping directly when ordering. Selection fields are available for this purpose.
Please indicate the setup you are running in the comment field at checkout when ordering. It is important to specify which slip-on exhaust (Yoshimura, Shark, Akrapovic, Boss, Copra, ...) and which air filter (K&N sport air filter, BMC, Rade Garage, ...) you are using, and whether you have a catalytic converter installed.

Process:
1. Order the FLAWLESS ECU Performance Flash or your ECU software optimization for your Yamaha YZF-R9 from 2025 with the desired options.
2. Send your ECU or control unit 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
In order 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 slip-on exhaust (Yoshimura, Shark, Akrapovic, Boss, Copra, etc.) and a sport air filter (K&N sport air filter, BMC, Rade Garage, etc.). The control unit will not be damaged or opened. The FLAWLESS ECU Performance Flash is not externally visible.
