BMW F Chassis B58 B48 B46 B38 Flex Fuel Ethanol Content Sensor for E85 Fuel Monitoring

Know your exact ethanol content in real-time with our new LED display or by using the BMS CANflex, Fuel-It! or JB4 mobile app on your smartphone or tablet.

If you’re running E85 or ethanol mixes in your B58, B48, B46, or B38 equipped BMW, you need this kit!

As many of you know the BMW motors can be very picky about how much ethanol you run to achieve peak performance but not run lean. Consequently, we have put together a kit enabling you to easily install an ethanol sensor with no permanent modifications needed. You will simply remove your low pressure fuel line in the engine bay and plug in our kit. It’s a complete plug-in solution that utilizes our Bluetooth app to monitor your ethanol content. When you are ready to return to stock, simply remove the kit and re-install the stock fuel line.

All kits include the following:

• Genuine Continental ethanol sensor
• One stainless steel braided fuel line with black nylon sheathing to protect your other engine bay components
• Proprietary custom billet fitting for plug and play OEM integration
• One custom wiring harness
• One tube of SuperLube for hose adapter install

Kit with BMS CANbus ECA includes:

• Our new CANflex LED Ethanol Content Analyzer (ECA) to display current ethanol content
• Legacy 5V output for JB4 integration
• Universal CANbus harness for use with future flash tuning integration
