1、Fits for Hyundai ix35 2010‑2015, providing 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 a driver’s perspective, with this "power mode" enabled, your car feels faster and more responsive than before adding the controller. 3、Features 3 driving modes. Normal mode: the 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, ideal for racing. 4、It can save more than 15% of fuel and improve the power response by more than 68%. Compact size, ultra‑thin thickness, enables it to be mounted anywhere without affecting the interior design. 5、Plug and play, simple to install, no need of external power supply (absolutely no cord cutting, no OBDII socket), special plug for each specific car model, which is more dependable to use.
