Got the ECU re-flashed with Flash Tune. Pretty simple digging out the ECU. Had to crank a bit more than usual to start the bike initially and was greeted with a loud backfire upon starting. Took her for a quick spin and right away I can tell the on/off/on throttle response is better. After deceleration into a bend, I can "feel" the engine immediately picking up the throttle as I begin to feed it in. Previously there was not much feel until the ECU turned the injectors back on after you already had the throttle starting to open, producing a jerk. Still a big difference between sport and touring mode, but T mode feels more normal now, if that makes any sense. Throttle response is better and smoother in both modes. The heavy engine braking is reduced maybe by half? So far so good.
