What is EFFuel?
EFFuel is connected directly to your car's ECU. The socket is standard on all cars.
AI Adaptable Configuration
After installation, EFFuel needs around 150 miles of usage to understand your car's behavior and adapt to your driving style
so it can start saving efficiently without compromising throttle.
The EFFuel device will enhance the performance of the car by remapping the ECU, adjusting the boost pressure, injection timings and fuel injection.
No power compromises
The Fuel Saver uses almost no power, so you won't have to worry about your car's battery health.
No throttle loss
The Fuel saver does not compromise your throttle, it actually increases it!
