A little off the subject but still related ...
The Ford/Navistar Turbo Diesel uses electronically actuated unit (individual
cylinder) injectors. Because diesels don't use a throttle, this makes these
vehicles true "drive-by-wire".
There is only one computer in the system. The accelerator pedal assembly has a
potentiometer for "pedal position" and closed throttle and WOT switches. Speed
(cruise) control is handled by the same processor. For vehicle that require a
auxiliary/hand throttle (ie. wreckers w/PTO and vehicles that require high idle
for high electric power output) there is a separate controller (microprocessor
based) that tells the EEC to go to high idle.
