BT Tune | Aprilia (12-20) RSV4 Stage 1+ ECU Flash With Tuner

Through careful testing of the stock ECU and Race ECU calibration, we were able to find 22 power maps and limiters holding back the otherwise stout 180HP powerplant. Our RSV4 Stage 1+ ECU Calibration with Handheld Tuner converts the bike to full "Alpha-N" fueling and utilizes the factory oxygen sensors for precise fuel corrections, both on and off throttle. Improvements in throttle response, ridability, cruising and of course, POWER were all immediately apparent. Limiters raised for racing and road course use where you need to extend gears is taken care of across the board.

ADVANTAGES WITH STAGE 1

• On average, gains of 7-10HP were found over the Race ECU baseline on a typical exhaust/filter bike on 93 octane fuel (Larger gains with VP race fuel).
• Early Fan-On - At 195 degrees, your Aprilia starts to pull power from the engine.  We change this to 185 degrees.
• Changes to fueling including part, mid and full throttle while in AlphaN configuration.
• Optimization of ignition timing at part and mid throttle for all fuel qualities.
• Adjustments to torque limiting to allow the bike to make 100% of it’s available engine torque.
• Changes to rev limiter per-gear tables for widest and safest possible powerband.
• Aggressive adjustments to engine braking along with decel fueling for road course use.
• Changes in factory unstable engine idle for stability and consistency off throttle.
• Changes to a full 100% throttle opening in all modes, verses a limited table.
• Gains throughout the whole curve on all fuel qualities with no loss in power anywhere on the RPM band.
• Changes to ABS, DTC, and wheelie intervention for more available power and control for a performance oriented rider.
