Automobile throttle controller can save more than 15% of fuel and improve power response by more than 68%. The compact size and ultra-thin thickness enable it to be installed anywhere, and the installation is simple without affecting the interior design Feature: 【SCOPE OF APPLICATION】 Automobile throttle controller has a wide range of applications, suitable for Forester 2006-on, providing faster and more active acceleration. For example, as a standard, 10% of the pedal input will provide the ECU with a 10% accelerator signal, but when you only have 10% of the throttle input, the throttle controller may send a 30% message to the ECU. 【EXCELLENT PERFORMANCE】 The automobile throttle controller will immediately provide 30% of the signal to the ECU instead of smoothly accelerating over time. From the driver's point of view, when this "power saving mode" is enabled, your car feels faster and responds faster than before adding the controller.
