Now that Gen1 B58 tuning software supports true CAN-based Flex Fuel tuning, we are offering our 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. With a CAN-based ethanol sensor, the user can not only monitor ethanol content, but this sensor will also directly communicate with the DME for true 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 gas map and everything in between. This all happens on the fly, based on the live CAN-communication with our ethanol sensor. Gone are the days of doing math at the gas pump only to decide which map to flash and how many gallons of ethanol to mix!
