Throttle - Porsche 2015 911 GT3 Cup Technical Manual

1.5.2

Throttle

The electronic throttle controls the air supply to the engine by means of an integrated
electric motor. The use of a mechanical operator such as throttle cable is therefore
not required.
1.5.2.1
• Electronic throttle
• Redundant design by using 2 potentiometers
Throttle Setting
There is no mechanical connection between the throttle and accelerator pedal. The
electrical signal from the accelerator pedal is converted by an electric servo-motor in
the throttle into an opening angle.
A calibration of the throttle is not required. After switching on the ignition, the throttle
opens and closes automatically to determine its limits.
NOTE
Version: 16.12.2014
After switching on the ignition the starter button is
deactivated for 3 seconds as the throttle blade is going
through its calibration cycle.
