BT Tune | Aprilia RS 660 / Tuono 660 Stage (21-24) 1+ ECU Flash With Tuner

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 100HP powerplant. While the Tuono version is rated for 94HP, the final tuned number will be the same as the RS 660. That means bigger gains for the Tuono as it's more restricted than the RS 660.

With full in-person datalogging in our closed dyno cell, riding the bike on the street, and GPS speed testing, 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. 

Our Stage 1 Aprilia RS 660 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. 60-130MPH testing found a full second improvement from stock to flashed.

ADVANTAGES WITH STAGE 1

• On average, gains of 4HP peak and 10HP under the curve, over stock and MORE for Tuono. Even though this isn't a ton of peak power, we shaved over a full second off the 60-130.
• 2000 RPM more peak power over stock to carry to redline (see dyno tab)
• Early Fan-On. At 200 degrees, your Aprilia starts to pull power from the engine. We change this to lower temperature to avoid this power loss and stalling 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 11,500RPM to 12,200RPM
• 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
• Gains midrange to redline on all fuel qualities with no loss in power anywhere on the RPM band
• Enabled turn signals in headlight LED
