One of the most common questions we receive at iWire is "Is my engine Drive by Wire or Cable Throttle," so we've decided to post the definitive list! This list is also useful if you are looking into an engine swap so you can confirm which setup your new engine has.
What is it?
Drive by Cable (DBC) - If your car is cable throttle that means there is a mechanical cable that runs direct from the pedal to the throttle body to open (to accelerate) and close it (to slow down).
Drive by Wire (DBW) - If your car is electronic throttle that means there are electrical wires that connect the pedal to the throttle body via the engine computer (ECU) so when you push the accelerator pedal the ECU interprets the signal and tells the throttle body to open or close.

iWire has also created a solution to one of the most common issues when swapping a car from cable throttle to DBW - the pedal! Check out our Drive By Wire Pedal Adapter Bracket.
Swap Options:
Cable Throttle to Cable Throttle: Going from cable throttle to another cable throttle engine is generally very simple.
Cable Throttle to DBW: Swapping your engine from cable throttle to drive by wire is a straight forward process with our merge services and a pedal adapter bracket. It can be slightly complicated when doing DIY.
DBW to Cable Throttle: Going from drive by wire to a cable throttle setup can be done but does create a few issues with the pedal and cruise control.
DBW to DBW: Drive by wire to drive by wire swaps allow you to keep your current pedal set and cruise control working.
