Target Engine Speed
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2007 MINI Cooper, 2006 MINI Cooper, 2005 MINI Cooper, 2004 MINI Cooper, and 2003 MINI Cooper. However, it is still accessible from the selected car via links, so may be relevant.
The target engine speed is critical in deciding the position of the ratio control motor. The EMS 2000 will keep changing the ratio of the motor to achieve the target engine speed. The target engine speed is mapped inside the EMS 2000 against Road speed and Driver demand (throttle angle).
The map is not linear. To achieve good driving characteristics the engine target speed map is programmed to overcome:
- The initial engine speed required to build pressure within the hydraulic clutch.
- The hydraulic profile of the transmission itself.
- The engines power and torque profile.
When the transmission is operating in the D mode (drive), the driver does not experience full engine power until the road speed reaches 50 mph.
