BT Tune | Aprilia RSV4 (21-24) Stage 1+ Performance Calibration With Handheld Tuner

Through careful testing of the Stock ECU and Aprilia Race ECU calibrations, we were able to find 27 power maps and limiters holding back the otherwise stout 217HP powerplant.

As tested on our YouTube video (see below) to exact a 10+whp gain over stock. It has been through many different tuning providers and agreed to bring the bike to us to develop an extraordinary file. With full in person datalogging in our closed dyno cell, we were able to find what the engine really liked and disliked. 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.

Our Stage 1 RSV4 1100 Factory ECU flash converts the bike to full “Alpha-N” fueling and utilizes the factory oxygen sensors for precise fuel corrections on and off throttle. Improvements in throttle response, rideability, cruising and of course, power, were all immediately apparent. Limiters raised for racing and road course use where you need to extend gears. 205MPH is found on the factory GPS meter with ease. 

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 194 degrees to avoid this power loss and stalling from overheat 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
• Adjustments to torque limiting to allow the bike to make 100% of its available engine torque at high load
• RPM limiter raised from 13,600RPM to 14,200RPM
• Changes to rev limiter per-gear tables for widest and safest possible powerband as the factory 1100 cuts short in lower and upper gears
• Aggressive adjustments to engine braking 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, versus a limited table
  
• Changes to ABS, DTC, and wheelie intervention for more available power and control for a performance oriented rider.
  
• Enabled turn signals in headlight LED's
• We recommend dropping a tooth in the front sprocket or up 2 in the back sprocket for best performance
