Ultimate9 (formerly iDrive) has dominated the 4X4 market since its inception.
Rather than a traditional accelerator cable, Many modern vehicles now use 'fly by wire' throttle technology.
The Ultimate9 Throttle Controller plugs into this technology through the accelerator pedal with plug and play
(no cutting of wires required)and measures the pedal position and pressure applied which is communicated through
the Throttle Controller unit before being sent to the vehicle computer.
These settings can be adjusted to be more or less responsive throttle control or even can be set to factory standard
so no need to unplug the unit to return back to normal.
