{"product_id":"bmw-ffk-e01-bluetooth-flex-fuel-kit","title":"BMW FFK-E01 Bluetooth Flex Fuel Kit","description":"The FlexFuel BMW-FFK-E01 is a complete plug-and-play kit engineered for BMW 135i and 335i E-Chassis vehicles equipped with N54 and N55 engines. This system enables drivers to run E85 or ethanol blends by replacing the stock fuel lines with an upgraded, E85-compatible -6AN line. It integrates a Bluetooth-enabled ethanol sensor and analyzer, providing real-time ethanol content readings directly to your smartphone or tablet via the Fuel-It! or JB4 mobile app.\n\nThe kit offers both Bluetooth app connectivity and a 5v analog output suitable for JB4 or flash tuning. The system comes with options for various fuel line configurations, including direct replacement from the HPFP to the fuel tank, or integration with port injection systems from Fuel-It! or Phoenix Racing.\n\nSpecific instructions are provided for JB4 integration: on N54 E-series platforms, connect the white wire to position #15 on the JB4 25-pin harness and select the WMI Ethanol Setup option 1; for N55 E-series platforms, connect to position #16 and select the same setup option. All kits are explicitly noted as being for off-road use only.","brand":"FlexFuel","offers":[{"title":"Default Title","offer_id":52688379773240,"sku":"BMW-FFK-E01","price":620.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663174128.webp?v=1784889354","url":"https:\/\/store.motormia.co\/products\/bmw-ffk-e01-bluetooth-flex-fuel-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
