Dorch Engineering BMW B58 Gen 1 Flex Fuel Kit ECA Plug and Play

The Dorch Engineering B58 Gen 1 Flex Fuel ECA Kit is the ultimate plug-and-play ethanol content analyser for Gen1 B58-powered BMWs, fully compatible with the latest MHD and Bootmod3 (BM3) tuning platforms. Thanks to recent software advancements, Gen1 B58 tuning now supports true CAN-based Flex Fuel tuning, eliminating the need for outdated Bluetooth ethanol sensors.

This CAN-based ethanol sensor doesn’t just monitor ethanol content — it directly communicates with the DME, enabling full Flex Fuel operation. With a Flex Fuel tune, your DME will automatically adjust your fuel, ignition, and boost settings based on real-time ethanol content, smoothly transitioning from a high-powered E85 map to a pump gas map, or anything in between. This seamless integration means no more manual calculations, map switching, or guesswork at the pump — your B58 is always running the optimal tune for the fuel blend in your tank.

The Dorch B58 Gen 1 Flex Fuel ECA Kit is 100% plug-and-play, requiring zero cutting or wire tapping, and is completely reversible. The wiring harness integrates directly with the OEM wiring, and the ethanol sensor and fuel lines tuck neatly away, allowing for full reinstallation of OEM sound insulation and engine covers — keeping your engine bay looking factory fresh.

To maximize accuracy, the ethanol sensor is mounted as close to the injectors as possible, ensuring that fuel mixture changes are detected and communicated to the DME instantly for precise real-time adjustments.

With a DIY-friendly, detailed installation manual, the kit can be installed in approximately 30 minutes when combined with a HPFP upgrade or about 1 hour on its own, depending on experience.

For BMW 340i, 440i, 540i, 740i, and other Gen1 B58 models, the Dorch Engineering B58 Gen 1 Flex Fuel ECA Kit offers the ultimate combination of precision ethanol monitoring, automatic Flex Fuel tuning, and easy installation, giving you the flexibility to run any fuel blend with total confidence and maximum performance.
