An electronic device modifies the signal between a vehicle’s accelerator pedal and its engine control unit (ECU). This modification alters the responsiveness of the engine to accelerator pedal input. For example, a setting might increase initial acceleration for a sportier feel, while another might dampen the response for improved fuel efficiency in city driving.
Such devices offer drivers greater control over their vehicle’s throttle response, potentially enhancing driving experiences and fuel economy depending on individual driving styles and preferences. The development of these devices stems from the increasing prevalence of electronic throttle control in modern vehicles, replacing traditional mechanical linkages. This shift allowed for more precise control and optimization of engine performance, opening the door for aftermarket modifications.
