B58 GEN1 FLEX FUEL ECA KIT

Dorch Plug-and-Play CAN-Based Ethanol Content Analyzer (ECA) Kit for BMW B58 Gen1

Experience seamless Flex Fuel tuning with our innovative CAN-based Ethanol Content Analyzer (ECA) designed specifically for Gen1 B58 BMW engines. Leveraging the latest support in MHD and Bootmod3 tuning software, this kit eliminates the need for traditional Bluetooth ethanol sensors by directly communicating ethanol content to the DME via CAN bus for real-time, automatic fuel map adjustments.

Key Benefits:

• True Flex Fuel Operation: The DME dynamically switches between E85 and pump gas fuel maps based on real-time ethanol content — no manual map switching required.

• Plug & Play: No cutting, wire-taps, or permanent modifications. The harness plugs into the OEM wiring with OEM-style connections.

• Fast & Accurate: Sensor mounted close to the injectors ensures minimal lag for precise ethanol percentage monitoring right at the combustion chamber.

• Fully Reversible: Original factory sound insulation and engine covers can be reinstalled with no permanent changes to your vehicle.

• DIY-Friendly Installation: Takes about 30 minutes if paired with an HPFP install, or about 1 hour solo.
