Drive-by-wire, Adjust by ATCC. Fine tuning how you put the pedal to the metal.

ARK Design's Accelerator Throttle Curve Controller (ATCC) is an add-on electronics unit that modifies your vehicle's drive-by-wire throttle signal output and allows you to modify acceleration response to your liking. The unit can be adjusted to increase or decrease accelerator sensitivity in up to 10 increments between closed throttle and wide-open throttle.

Control is the ATCC's middle name

Five selectable control modes insure the best application for your driving situation.



ECO Drive Mode : Promotes fuel economy by reducing the throttle opening and sounding an alarm under non-economic driving styles



SPORTS Mode : Increases throttle signal for faster transient throttle response.


MEMORY MODE 1/2 : Two user-defined memory settings allow for the ultimate in acceleration control precision.
