The Flex Box allows you to operate your vehicle on any combination of ethanol and gasoline such as E85 (85% ethanol, 15% gasoline), E-20, E-10 or pure gasoline.

The secret is in the system’s intelligent fuel injection components. When operating on E85, or a mix of E85 and gasoline, your engine needs a greater amount of fuel injected into the engine to keep the fuel/air mixture in the optimum zone. Once installed, Flex Box continuously monitors your vehicle’s engine emissions and adjusts supplemental fuel injection which allows your vehicle to operate at optimal performance. So you don’t have to worry about the type of fuel you use as long as it’s some combination of gas and ethanol. When you fill up at the pump, you can choose your fuel based on price, availability, or a simple interest in caring for the environment or reducing dependence on foreign oil.
