BT MOTO Aprilia RSV4 (21-25) ECU Flash Stage 1

BrenTuning Stage 1 ECU Flash – Aprilia RSV4 

Through careful testing of the Stock ECU and Aprilia Race ECU calibrations, we were able to find 22 power maps and limiters holding back the otherwise stout 205HP powerplant.

 Through careful logging of ignition timing, per cylinder fueling and thermal management limiters, we were able to write an excellent file that is powerful in all temperatures and covers all octanes. The engine is an extreme powerhouse. After reviewing the stock and Race ECU data, we were able to determine some impressive improvements could be found with time invested in a proper calibration. We were able to get larger gains under the curve and top-end improvements on 93 and MR12. Check out the same day testing (look below) of Racing ECU vs BT 93 vs. BT VP Race gas.

ADVANTAGES WITH STAGE 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)
• Early Fan-On – At 200 degrees, your Aprilia starts to pull power from the engine. We change this to 185 degrees to avoid this power loss in stop and go traffic
• Changes to fueling including part, mid and full-throttle while in Alpha-N configuration per cylinder
• Optimization of ignition timing at part and mid throttle for all fuel qualities
• M-Torque adjustments to torque limiting to allow the bike to make 100% of its available engine torque at high load in every gear
• Changes to rev limiter per-gear tables for widest and safest possible powerband as the factory 1100 cuts short in lower and upper gears
• Changes in factory unstable engine idle for stability and consistency off-throttle
• Changes to a full 100% throttle opening in all modes, versus 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
• We recommend dropping a tooth in the front sprocket or up 2 in the back sprocket for best performance
