Fly-by-wire anything (car, motorcycle, plane) is a system where the throttle is not connected to a carb or throttle body by actuating cable. Usually some type of potentiometer at the throttle that is connected, by wire, to an electronic actuator on the other end. Vey handy in manufacturing if you don't have to thread a cable or set of cables.
Benefits of Drive by Wire (DBW) Throttle. No throttle cable issues: While a throttle cable represents a remarkably simple solution, it does have its drawbacks. Over time the steel cable can stretch, and it may require adjustments to allow proper idle and full-throttle operation.
TACOMATruckin98. drive by wire = throttle plate is not mechanically controlled ( throttle plate opening/closing controlled by a cable). it has a sensor on the gas pedal to determine gas pedal position, then the signal is relayed to the ecm/ecu. after that the ecm/ecu sends a signal to open/close the throttle plate via a small motor on the
In this article, we focus on "throttle by wire" technology. It is one of the safer designs to implement as compared to an electronically-controlled steering or braking system. Often known as electronic throttle control (ETC), this system replaces the mechanical connection between the throttle pedal and the throttle valve of the engine.
The solenoid that most drive by wire throttle bodies have can respond extremely quickly, to the point where there really is no difference between it and a cable. ECU tunes tend to help with this, they can help tune out the delay or lag that an electronic throttle sometimes creates. I have considered a stage one tune for my jetta almost entirely
