What is EFFuel?

With the price per gallon increasing over the past few years, people have long started for the search of devices that will help them save money. The search is over! That device is finally here: EFFuel is a Fuel Saving Device that will help you reduce your fuel consumption by up to 35%. The device can be used on all cars, as it uses the standard ECU OBD2 socket present in all cars for diagnostics and remapping. The Fuel Saving Device will need around 150 miles of driving after installation so it can start automating the savings process based on your engine's parameters and your driving behavior. If you have more drivers on a single car the device can build up to 3 profiles and identify the driver autmatically.

Why choose EFFuel

The Eco EFFUEL OBD2 device will help you reduce your Gas Consumption to up to 35% while actually improving your throttle.

How to install

The EFFuel Device is Plug and Play. This means that all you have to do is plug it into your ECU(electronic control unit) usually located between the pedals and the steering wheel.


100% Compatibility
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.

Improved Performance
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!

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.
