@DannyP posted:.Old way: throttle cable directly connected to throttle body.
New way: Gas pedal has a potentiometer(variable resistor) and a heavy spring.
Throttle body has a stepper motor attached directly to drive the throttle plate.
Electronic controls and wires in-between the two, ..
The benefit is possibly quicker throttle response…
This always sounded to me like there were too many engineers on the payroll.
