Ducati Diavel Service Manual: Specific operating strategies

Idle speed

No electric motor is used for idle speed regulation (bypass is modulated instead with the throttle valve), as idle speed control is effected by the ride-by-wire system. Idle speed is maintained by the control unit when the speed drops below a specific threshold and when the clutch lever is operated and/or the gearbox is in neutral. The "clutch lever operated" signal is generated by a button on the lever itself, which interacts directly with the engine control unit. The "gearbox in neutral" signal is generated by the gear sensor connected to the bbs, and is transmitted to the engine control unit via the can line (target idle speed with engine stabilised at operating temperature is 1,350 rpm). The co value for each cylinder, always with engine stabilised at operating temperature, must be within 0.4 And 1.4 In volume percentage.

Throttle valve aperture regimens

The rider may select between four different riding modes (sport, touring, urban) from the tank dashboard and via the handlebar controls. Each riding mode contains three configurable throttle valve opening strategies (the engine control calibration parameters, in other terms the maps for quantity of fuel injected and ignition timing advance, are the same for all). This allows the rider to adapt power delivery and maximum power as follows to suit personal preferences:
