The Dorch Engineering BMW S58 Flex Fuel ECA Kit is a plug-and-play ethanol content analyzer designed for BMW G80 M3, G81 M3 Touring, G82 G83 M4, G87 M2, as well as F97 X3M and F98 X4M models — delivering seamless Flex Fuel capability to all S58-powered BMWs. With the latest S58 tuning software now supporting CAN-based Flex Fuel tuning, this kit allows the DME to automatically adjust your tune based on real-time ethanol content, eliminating the need for manual map switching or calculating ethanol blends at the pump. Whether you’re running pump gas, E85, or any blend in between, your BMW S58 Flex Fuel ECA Kit ensures the DME seamlessly optimizes power and performance.

This BMW S58 Flex Fuel ECA Kit is fully plug-and-play with no wire taps or cutting required, making installation completely reversible. The wiring harness connects directly to the OEM harness, and the ethanol sensor and hoses tuck neatly away, allowing for full reinstallation of all factory sound insulation foam and engine covers for a clean, OEM-style appearance.

The ethanol sensor is mounted as close to the injectors as possible, ensuring instant ethanol content readings, so the DME receives real-time data with virtually no delay, allowing for precise and immediate fuel adjustments.

Despite the detailed and user-friendly installation guide, most enthusiasts can expect a total install time of approximately 1 hour, depending on experience. The Dorch Engineering BMW S58 Flex Fuel ECA Kit is the perfect solution for BMW G80 M3, G81 M3, G82 G83 M4, G87 M2, F97 X3M, and F98 X4M owners who want to unlock the full power potential of Flex Fuel tuning, while maintaining OEM-level fit, finish, and reliability.
