Zeitronix Ethanol Content Sensor Kit

The Zeitronix Ethanol Content Sensor Kit is the trusted standard for measuring ethanol content and conveying that data to the ECU for Flex Fuel Tuning.   Ethanol Content Sensors are Digital Sensors which works well for standalone ECUs.  

If you are running an OEM ECU with a tuning software such as ECUtek than the Zeitronix module coverts the digital ethanol content and fuel temperature content into two 0v - 5v analog signals that can be imported and recognized by the OEM ECU.

Note: In some cases modifying the existing engine bay harness will be required and may influence the emissions / evap systems.   


  • Two 0v-5v analog signal outputs: (Ethanol Content and Fuel Temperature)
  • Error indication in event of signal absence from Flex Fuel Sensor
  • 3/4” thick gauge is completely flat with cable hidden in a cavity and can be surface mounted almost anywhere inside the car or in a 2 1/16” pod.
  • Power and serial data is supplied directly through a simple single connection
  • ECA-2 dimensions: 3" x 2" x 1" and can be stored in glovebox, under the dash, console, or other discrete location.
