Overview

The Zeitronix ECA-2 Ethanol Content Analyzer Kit is a universal kit designed to monitor the ethanol content of fuel before it enters your engine. This analyzer is crucial for tuning and racing E85-fueled vehicles, as the actual ethanol content can vary significantly from advertised levels. The kit provides two 0-5V analog outputs for ethanol percentage and fuel temperature, compatible with ECUs and data logging systems.

Show original supplier description

The Zeitronix ECA-2 Ethanol Content Analyzer Kit offers performance drivers precise control over their E85 fuel blends. It monitors ethanol content in real-time, ensuring optimal engine tuning and maximizing horsepower, especially when fuel stations may advertise E85 but deliver lower percentages like E70. Key features include two 0-5V analog outputs, one for ethanol percentage (0-100%) and another for fuel temperature (-40°C to 125°C). These outputs are essential for integration with ECUs and data logging systems, allowing for sophisticated flex-fuel tuning. The analyzer itself is compact, measuring 3" x 2" x 1", and features a gauge that is only 3/4" thick with a flat back for versatile mounting options, including within a standard 2-1/16" gauge pod. Power and data are supplied through a single connection, simplifying installation. Installation requires careful consideration. A professional installation by a shop familiar with your vehicle's fuel system is recommended to ensure safety and proper function. It is crucial to always check for fuel leaks after installation. The kit can be optionally purchased with a Zeitronix Flow Through Flex Fuel Sensor and an 8 ft harness. The ECA-2 is compatible with some OEM sensors found in GM vehicles that display the flex fuel insignia or are designed to run on E85. However, it's important to note that GM offers various sensors with different specifications. The kit itself is manufactured in the USA.
