Dorch Engineering Plug and Play Flex Fuel Kit (ECA) - BMW F20 M140i | F22 M240i | F30 340i | F32 440i (B58 Gen1)

The Dorch Engineering plug and play Flex Fuel ECA kit brings true CAN-based flex fuel to the Gen1 B58. The genuine Continental ethanol sensor not only monitors ethanol content but communicates directly with the DME, so a flex fuel tune can blend seamlessly between a high-powered E85 map and a pump fuel map – no more working out mixes at the pump or reflashing maps.

With zero cutting and zero wire-taps, the kit is fully reversible. The harness integrates with the OEM loom and the hoses and sensor tuck neatly away, allowing all OEM sound insulation and engine covers to be refitted.

Please note:

• A flex fuel compatible tune is required (supported by MHD and Bootmod3 on the Gen1 B58).
• Please select the high pressure fuel pump currently fitted to your car (Dorch, Dorch OG or OE TU pump) and your model range.
• Installation adds roughly 30 minutes to an HPFP install, or around 1 hour on its own, depending on skill level.
• Only suitable for Gen1 B58 vehicles up to the 2019 model year – not compatible with 2020-on B58 vehicles.
