Ducati Diavel Service Manual: Introduction to the engine control system
The engine control system used on the diavel consists of the following elements:
- Ride-by-wire system (motorised throttle valves with electric actuator, throttle grip position sensor and throttle valve position sensor)
- One injector per cylinder installed downstream of throttle valve
- One coil per cylinder, in spark plug bore
- Two oxygen sensors (one per cylinder, installed on each exhaust manifold)
- Two absolute pressure (map) sensors installed downstream of throttle valve (one per cylinder connected to each intake duct)
- One three-way catalytic converter for exhaust gas post-treatment
The system also includes conventional sensors for water and air temperature, engine speed-timing etc.

Programming/reprogramming keys
The dds diagnosis instrument is required in order to programme/reprogramme
the keys. The key programming procedure
is launched from this instrument.

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 ma ...

Tips on how to select the sensitivity level
Warning
The 8 level settings of the dtc were calibrated using
tyres of the same make, model and size as those originally
fitted to the motorcycle.
The use of tyres of different size to the original tyres may
alter the operating characteristics of the system.
In the case of minor differenc ...
