Show original supplier description
The FlexFuel N55 Bluetooth Flex Fuel Kit is designed for F-Series BMW models equipped with the N55 engine, enabling real-time monitoring of E85 or ethanol fuel mixes. This complete plug-and-play kit replaces the stock fuel lines from the fuel tank to the engine bay with an upgraded -6AN E85-compatible fuel line. It integrates an ethanol sensor and a Bluetooth analyzer, allowing you to accurately track your ethanol content. This system provides dual output options: Bluetooth connectivity for use with the dedicated Fuel-it! app on iPhone or Android devices, and a 5v analog output compatible with JB4 or flash tuning interfaces. The kit's fuel line upgrade varies depending on your existing setup, with options for stock HPFP to fuel tank configurations, or integration with various port injection systems (Fuel-It!, Phoenix Racing Manifold, or non-Fuel-It! kits). Custom billet aluminum fittings are used to ensure seamless integration with stock components, requiring no modifications. Installation involves connecting the included fuel lines and sensor, with specific wiring instructions provided for BMW F-series PWG and EWG JB4 platforms. The product is noted to be available for off-road use only.
