2015 Ducati Superbike 1299 Panigale S Owners Manual - Page 69

The DQS with up/down feature allows the rider to upshift and downshift without using the clutch lever. It includes a two-way microswitch - built in the lever mechanism - that outputs a signal to the engine control unit whenever the gearshift is operated. The system works in a separate way for upshifting and downshifting, and combines the action on ignition advance and injection, available in the upshift system, with controlled throttle opening for operation during downshifting. Extent and duration of these actuations aim at ensuring excellent engagement smoothness under any riding condition; system works in synergy with slipper clutch and EBC during downshifting. When downshifting, according to the EBC level set by the rider, the DQS strategy changes the extent and duration of throttle opening so as to modulate engine brake exactly when a lower gear is engaged. With EBC set to OFF and 1, rider obtains maximum engine brake; medium engine brake in level 2 and the least engine brake in level 3. For further details on level selection, refer to paragraph page 75 concerning the EBC system. The user can decide whether to activate only the upshift feature or both up and down features of the DQS, using the relevant menu on the instrument panel. 67
