Dorch Engineering BMW B58 Gen1 Flex Fuel ECA. Now that Gen1 B58 tuning software supports true CAN-based Flex Fuel tuning, Dorch Engineering are offering their own plug-and-play ECA solution! With MHD and BM3’s new features, there is no longer much of a need for Bluetooth ethanol sensors. A CAN-based ethanol sensor can, not only monitor ethanol content but directly communicate with the DME for full Flex Fuel operation! With a Flex Fuel tune, the DME will automatically adjust the tune from a high-powered E85 map, all the way to a pump fuel map, and everything in between. This all happens on the fly, based on the live CAN-communication with the ethanol sensor. Gone are the days of doing maths at the fuel station only to decide which map to flash and how much ethanol to mix!
ZERO cutting and ZERO wire-taps! This kit is fully reversible and truly plug-and-play. The wiring integrates into the OEM harness and hoses and sensor tuck seamlessly to allow for the reinstallation of all OEM sound insulation foam and engine covers. With the ethanol sensor mounting location as close to the injectors as possible, there is virtually zero lag time on the exact ethanol mixture truly entering the combustion chamber.
Don’t be fooled by Dorch's extensive and overly detailed DIY-friendly instruction manual! You can expect this kit to add about 30 minutes to a traditional HPFP install or to take about 1 hour on its own, depending on skill level.
