2021-2023 APRILIA RSV4 SFN Handheld Tuning Tool

SFN Tuning offers Handheld Flasher’s for your APRILIA RSV4  motorcycle. Our tuning transforms the performance and riding of your bike, giving you a new racing experience. With our ECU flash, we are improving the full power curve, with changes to fueling, ignition, and limiters.  We increase horsepower and throttle response all around the power curve.

What is included in our SFN Handheld Flasher?

1. On average, gains of 7-14HP from the midrange and up were found over the baseline on a typical exhaust/filter bike with 93 octane fuel in the tank (Larger gains with race fuel)
2. Early Fan-On – At 200 degrees, your Aprilia starts to pull power from the engine. We change this to 194 degrees to avoid this power loss and stalling from overheat in stop and go traffic
3. Changes to fueling including part, mid and full-throttle while in Alpha-N configuration per cylinder
4. Optimization of ignition timing at part and mid throttle for all fuel qualities
5. Adjustments to torque limiting to allow the bike to make 100% of its available engine torque at high load
6. RPM limiter raised from 13,600RPM to 14,100RPM
7. Changes to rev limiter per-gear tables for widest and safest possible powerband as the factory 1100 cuts short in lower and upper gears
8. Aggressive adjustments to engine braking For road course use
9. Changes in factory unstable engine idle for stability and consistency off-throttle
10. Changes to a full 100% throttle opening in all modes, versus a limited table
11. Gains throughout the whole curve on all fuel qualities with no loss in power anywhere on the RPM band
12. Changes to ABS, DTC, and wheelie intervention for more available power and control for a performance oriented rider
13. Corsa ECU base upgrades are standard and included
14. Enabled turn signals in headlight LED’s
15. We recommend dropping a tooth in the front sprocket or up 2 in the back sprocket for best performance
