Zeitronix Ethanol Content Analyzer (Red)
Real time display of fuel ethanol content from 0% to 100%
Displays fuel temperature in Fahrenheit and Celsius ranging from -40 to 125 °F (-40 to 52 °C)
Error indication in event of signal absence from Flex Fuel Sensor
Two analog outputs: Ethanol % and Fuel Temperature for use with datalogging or engine management systems
Surface mountable sleek aluminum enclosure with bright LED display visible even in direct sunlight
A flex fuel sensor is required. The ECA is compatible with standard OEM sensors used in most vehicles with the flex fuel insignia or which run on E85
Dimensions: 2.8 x 1.8 x 0.75 inches (71 x 46 x 19 mm)
Note: A flex fuel sensor is not included with purchase of the ECA. Sensors are standard components of many flex fuel vehicles and may be purchased separately at GM dealerships (GM part number 12568450 or 12570260) or directly from our order page.
What's your ethanol percentage?
The ethanol content of E85 fuel can vary from 60% to 92% ethanol. A fill up with E85 can drastically change the mix of fuel in your vehicle. For performance drivers determining actual ethanol content of E85 is essential to maximizing an engine tune and horsepower.
ECA Analog Outputs
Ethanol content and temperature analog outputs are available as part of the ECA. The flex fuel sensor does not provide these outputs. We have created the ECA to provide these outputs making use of E-85 easier with after market engine control modules and data logging systems.
Analog Outputs Signal Range
Ethanol Percentage 0-5 Volts 0% to 100%
Fuel Temperature 0-5 Volts -40 to 125 °C (-40 to 257 °F)
Ethanol % = 20 * Voltage Fahrenheit Temp. = -40 + 59.4 * Voltage Celsius Temp. = -40 + 33 * Voltage
