Converting over to flex fuel requires that your fuel management system be calibrated to run on E85. Flex Fuel U.S. www.flexfuelus.com developed the first EPA certified flex fuel conversion kit for Dodge 5.7L, 6.1L Hemi motors. The kit is similar in nature to a nitrous injection system. The kit comes with a 60lb Bosch racing injector that gets installed into a separator plate supplied with the kit, and than is bolted directly behind the throttle body. An alcohol sensor is plumbed into the fuel stream. A high-speed processor receives signals from the alcohol sensor as well as from the engine, and determines an exact amount of fuel the Bosch injector adds to keep the engine run at an optimal 14.7:1 air/fuel ratio creating maximum power and excellent fuel economy.
