1、Fits for KIA Sorento 2015‑2020, offering faster and more aggressively acceleration. For example, as a standard, 10% of the pedal input will provide a 10% accelerator signal to the ECU. The throttle controller may send a 30% message to the ECU when you only have 10% throttle input. 2、It will give the 30 percent signal to the ECU straight away instead of smoothly accelerating over time. From the driver's point of view, with this "power mode" enabled, your car feels faster and more responsive than before adding the controller. 3、With 3 driving modes. Normal mode: your car is returned to its original factory settings. Econ mode: throttle response is slower, suitable for driving on congested roads, and save fuel. Race mode: the fiercest acceleration mode, the fastest acceleration response among the sport mode,, suitable for racing. 4、Brings +15% fuel saving and +68% power response, practical to use. Compact size, ultra‑thin thickness, enables it to be mounted anywhere without affecting the interior design. 5、Easy and fast installation, just plug and play, no need of external power supply (absolutely no cord cutting, no OBDII socket), special plugs for each specific car model, safer and more reliable.
