Golf 5 Sprint Booster
Most cars in the 21st century have replaced the more conventional throttle cable for an ETC, Electronic Control Module, that translates how hard the pedal is pushed into electronic signals in order to provide power to the wheels. The ETC which is also known as Drive-By-Wire, has the unfortunate downside of delayed response and subdued acceleration, which can create problems in certain situations such as up-hill starts, quick gearchanges and overtaking.
The Sprint Booster aims to overcome this throttle response delay for ETC equipped vehicles, by providing crisp, on-tap acceleration for whenever the driver demands it. It is a device that improves acceleration by continuously measuring and converting the digital signal provided by the ETC potentiometer, and providing the ECM with a new, faster and more response signal.
