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.
EFFuel is connected directly to your car's ECU. The socket is standard on all cars. The OBD2 socket was made standard in 1996 in the US, so all cars made after 1996 are compatible!
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! It tweaks the car's parameters so that your car will have the same torque or more, with less fuel consumption.
The EFFuel device will enhance the performance of the car by remapping the ECU, adjusting the boost pressure, injection timings and fuel injection. This all adds up to a more efficient system that will save fuel keeping all the other "fun" things of your vehicle still active!
It doesn't affect your Engine
Our product works within the tolerance of the engine and does not apply any permanent settings to your ECU. Your factory settings are applied as soon as you disconnect EFFuel.
