1、The throttle Controller will make the acceleration happen sooner and more aggressively. For example, as standard, 10 percent pedal input will give 10 per cent throttle signal to the ECU. Add a throttle controller, and depending on the profile set, it may send a message to the ECU of 30 per cent when you're only at 10 percent throttle input. Plus, it will give the 30 percent signal to the ECU straight away, as opposed to smoothing the ramp‑up out over time. From a driver’s perspective, with this ‘power mode’ active, your car feels a lot quicker and more responsive than it did before adding the controller. 2、CAMMUS WINDBOOSTER 9 Mode 4S kings throttle controller adds some new functions: Lock mode (anti‑theft function), Mode memory function(Save, preset mode), Intelligent throttle response. 3、The fuel saving is 15% higher, the power response rate is 60% faster, the performance is better, and brings you more convenience. 4、Ultra‑thin 6mm, the compact size allows it to be installed anywhere without interfering with the interior design. 5、Plug and play without external power supply (absolutely no cutting of wire & does not use OBDII socket ), Specific plug for each specific car model, safer and more reliable，less than 5 minutes install.
