Automobiles in the 21st century have replaced the more conventional throttle cable technology for an ECM (Electronic Control Module) that translates pedal travel into electronic signals in order to provide power to the wheels.

The ECT system (Electronic Throttle Control) – also known as drive-by-wire – has the unfortunate downside of delayed throttle response and subdued acceleration, creating problems in certain circumstances such as up-hill starts, quick gearchanges, overtaking, etc.

The Sprint Booster aims to overcome this throttle response delay for ECT-equipped vehicles, providing crisp on-tap acceleration at the driver's disposal.


The Sprint Booster might very well be the "smartest" gadget on your car. It is a device that improves acceleration by continuously measuring and converting the digital signal provided by the ECT's potentiometer, and providing the ECM with a new and altered signal.

Installing Sprintbooster

The design of the Sprint Booster allows for its easy installation in all models, without the need to cut any wires or intervene in the automobile's electronics (it does not affect other systems such as electronic injection, ABS, etc.).

Its installation is extremely easy, requires no specific skills or tools – apart from a screwdriver – and takes only one minute. With the screwdriver in hand, you simply undo the safety connector clip and plug-in the device in the throttle's connector. The other end is plugged-in at the clamp that leads to the ECM. The device is "idiot proof" as one end is a male connector and the other female.

It can either be installed by you – using the easy step-by-step instructions below – or at any authorized dealer.

Installation Instructions:

Find the ECT connector under the steering wheel.
By undoing the safety clip with the screwdriver, unplug the connector and pull it in front of the pedal.
Plug-in the Sprint Booster and the cable back into its initial position.
Connect the ECM cable to the Sprint Booster.
Makes sure all connections are firmly in place.
Enjoy the drive!
Note : These are general instructions applying to most of the vehicles. In some vehicles installation may vary.

Target Car

The Sprint Booster is aimed at all drivers with ECT-equipped cars, who are after a safer and more exciting automotive experience.
