DD15 Operator Guide – Accelerating the Vehicle

Accelerating the Vehicle

The Accelerator Pedal (AP) was designed to communicate “percentage” accelerator pedal travel to the engine’s Motor Control Module (MCM). The engine will respond accordingly to the driver’s demand.‪

A throttle or governor characteristic you may need time to get used to is the DDEC Limiting Speed Governor. This allows the driver to command total engine response between idle and rated speed, such as accelerating at half throttle – an advantage when driving under slippery conditions.‪

If you require wide-open throttle engine response, either accelerating or just plain pulling hard, the throttle AP will have to be held to the floor. To obtain 100% fueling at any speed, the AP will have to be maintained at the fully pressed position.‪
