This universal E85 analyzer plugs directly into your Flex Fuel sensor (sensor kit sold separately) and outputs your ethanol reading on CANbus address 0xEC allowing your flash only DME and/or JB4 to read the ethanol signal. In addition it includes a harness plug for an optional low fuel pressure sensor (available from Fuel-It!) adding this critical tuning information to platforms like the B58 that don't include a factory low fuel pressure sensor.
Can be used with both rear mount and front mount sensor kits. Universal CANbus connections are attached using removable posi-taps based on mounting location. See wiring guide below.
