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 now includes a 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 also includes a 5V output for legacy integration to JB4 or flash maps that don't yet accomidate CANbus ethanol input. 

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.

Wiring Guide for universal harness
Red (originally Red/Green): 12v switched power via fuse tap or posi-tap
Black: Ground
Brown (originally Orange): CAN- (For front mount usually the factory yellow CANbus wire)
Green (originally Red/Blue): CAN+ (For front mount usually the factory red CANbus wire)
Blue: 5V legacy output for input into JB4 

Harness types:

1. Universal harness, this is a universal harness for use with JB4, BM3, MHD, ECUtek, etc. Installs in front or rear of car using included removable posi-taps.
   
2. PnP harness, this harness is a plug and play option with the following requirements.
1. It is only compatible with the BMW GEN2 B58 and S58 platforms with automatic transmissions.
2. You must be running a JB4, MHD, ECUtek, or similar tune
3. Flex fuel kit must be mounted in the engine bay near the ECU, rear mounted flex fuel kits must use the universal harness
4. Note BM3 is not compatible with the PnP harness and requires our universal harness!

LED:
Current ethanol mixture will be shown with 01 indicating an error reading the sensor. The ending decimal will light up if the unit has CANbus access.

Note: We can customize the transmit address, format, and transmit speed. Contact us if you have a special request.
