Universal BMS CANflex CANbus E85 Analyzer (ECA) BETA

This universal E85 analyzer plugs directly into your Flex Fuel sensor (sensor kit sold separately) and outputs your ethanol reading on CANbus 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.

CANflex is now also available with an LED readout! Route the new display box inside the cabin or glove box for a quick glance of your ethanol mixture or leave it in the engine bay under a plastic cover as a backup plan. Note the LED display is not water-proof and care should be taken to ensure it doesn't get soaked! CANflex LED has a dial inside that allows you to change between CANbus address modes for MHD, BM3, and JB4. Offered with the universal harness only.

Low fuel pressure monitoring is critical for any vehicle running higher power levels and especially those with port injection. Our optional 10 bar low fuel pressure sensor kit includes a sensor and 1/8" NPT angle tee for easy fitment. 

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.
