*Note: An ethanol analyzer must be used in conjunction with the ethanol sensor to read your ethanol content.
There are three options to read your ethanol content when using our ethanol analyzers:

  • Bluetooth only
  • Bluetooth and JB4 integrated (0-5 Volt) 
  • Bluetooth and 50-150hz Raw Signal
    • Bluetooth (Iphone or Android app must be purchased to use this feature)

*Ethanol sensor readings are based on the gasoline content of your fuel.  Fuel that has been contaminated can generate a false ethanol reading.
