Why flash an Aprilia ECU?
Aprilia’s parallel twins and V4s are built to be ridden hard, but they leave the factory with maps written for noise and emission limits. A reflash lets you set fuelling and ignition for your exhaust and your fuel, sharpen the response at small throttle openings and set the bike up for track days.
