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.
