Fuel-It! Bluetooth/CANflex Flex Fuel Kit - BMW F-Chassis B58 (240i/340i/440i)
$479.95
OVERVIEW
The Fuel-It! Bluetooth/CANflex Flex Fuel Kit lets your B58-powered F-chassis BMW (M240i, 340i, 440i) safely run E85 and any ethanol blend by monitoring real-time ethanol content and feeding it to your tune. Built around a genuine Continental ethanol content sensor with a stainless braided PTFE fuel line and plug-and-play wiring, it streams your fuel's ethanol percentage to the free Fuel-It!/BMS smartphone app over Bluetooth — unlocking the bigger power and cooler charge temps of flex fuel. Installs in about 30 minutes.
