Know your exact ethanol content in real-time via the Fuel-It! or JB4 app on your smartphone or tablet!
If you're running E85 or ethanol mixes in your BMW, you need this kit!
As many of you know the B58 motor is 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 and play solution that utilizes our Bluetooth app to monitor your ethanol content. When you are ready to return to stock, you will simply remove the kit and re-install the stock fuel line.

*For the Gen 1 B58 JB4 platform connect the white wire to position #16 on the JB4 25 pin harness. Then enable bit 1 (JB4 15/16 Flex Fuel input) on the WMI page in the JB4 settings.
*Ethanol Sensors don't actually read the ethanol content, the readings are based on the absence of gasoline, so if your fuel is contaminated your ethanol readings may be artificially elevated.
