Motronic ME 7
ElectronicThrottle Control
The ME 7 engine management system utilizes
electronic throttle control that enables the ECM to
control the intake charge volume and velocity for
optimization of engine torque.
The ECM positions the throttle valve according to
torque demands, allowing the ECM to control throttle
angle. This is a key factor in torque management.
The throttle valve control module allows the throttle
valve angle to be optimized for maximum intake
velocity.
The throttle valve control module has been modified
from the M5.9 system to allow the ECM to drive
the throttle valve under all running conditions. This
system no longer uses a mechanical link between the
accelerator pedal and the throttle valve housing (Drive
by Wire).
Extensive safety measures have been implemented
in the hardware and the software. Dual sensors are
used for continual self checking of signal plausibility. A
safety module is integrated in the ECM to monitor the
functional processor for proper operation.
