How does drive by wire work? Why is drive by wire throttle laggy and slow? Well… 

On this episode of Motorvate’s DIY garage, we are going to show you how drive by wire works, by make our own drive by wire system using an Arduino Uno clone, an old volume control (variable resistor) and a electronic throttle body from an Infiniti G37 (same as just about every Nissan or Infiniti) 

The traditional way to open and close the throttle was with a steel cable.

Today, just about every car uses electric motors, electronics and wires to control the

throttle.  This is known as a “drive by wire” system or electronic throttle control (ETC)

As a bonus, this episode also proves that a drive by wire system can have VERY quick throttle response.
