Fuel-It! Bluetooth/CANflex Flex Fuel Kit - BMW G-Chassis Gen2 B58 (M240i/M340i/M440i/540i)

OVERVIEW

The Fuel-It! Bluetooth/CANflex Flex Fuel Kit lets your B58-powered BMW M240i, M340i, M440i, or 540i 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 reads your fuel's ethanol percentage and streams it 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.
