Award Winning Zeitronix Ethanol Content Analyzer
ECA-2

First in Flex Fuel since 2008

Recipient of SEMA 2013/14 New Product Media Award

PURCHASE

• Two 0-5 V analog outputs: Ethanol % and Fuel Temperature for use with ECUs, data logging and engine management systems.
• Error indication in event of signal absence from Flex Fuel Sensor
• Optional real time E% Ethanol Content Gauge, Fuel Temperature Gauge and NEW Dual E% and Fuel Temperature Gauge.
  The gauge is only 3/4" (19mm) thick. The back of the gauge is completely flat with cable hidden in a cavity and can be surface mounted almost anywhere inside the car cabin using a piece of Velcro or double sided tape. The gauge base allows the gauge to be mounted in a standard 2” 1/16 (52mm) gauge pod. For additional mounting options the package includes 2 set screws and 2 nuts (4-40 screw size). Check out the gallery for gauge installation pictures.
  The gauge plugs into the ECA-2 GAUGE port.
  Both E% and Fuel Temperature Gauges can be plugged to the ECA-2 at the same time.
  Fuel Temperature Gauge shows Celsius and Fahrenheit. 
  Power and serial data is supplied directly through the single connection - there are no additional +12V or ground wires. The gauge cable length is 5 ft (1.5m).
  ECA-2 is required for gauges operation.
• Connecting harness to Zeitronix Flow Through FLEX Fuel Sensor is included. Harness length is 8 ft (2.4m)
• A flex fuel sensor is required.  The ECA-2 is compatible with some OEM sensors used in GM vehicles with the flex fuel insignia or which run on E85. However GM offers a large number of different sensors with different specs.
  ECA-2 Kit which includes Zeitronix tested Flex Fuel Sensor and can be purchased here.
• ECA-2 dimensions: 3" x 2" x 1" (76mm x 50mm x 25mm)
• Made in the USA!

Why know your ethanol percentage?
E85 has the equivalent octane rating of 105 octane gasoline.  Higher octane fuel is more resistant to knock allowing for more aggressive ignition timing, higher compression and increased engine power over gasoline itself.  The Zeitronix Ethanol Content Analyzer helps you get the most out of your engine and fuel.

What are the sizes of the flex fuel sensor inflow and outflow lines?
Zeitronix Flow Through Flex Fuel Sensor both tubes are 0.37" and 0.5" at the flange.

The usual mounting location for the sensor is the return fuel line.  Make sure the sensor is filled completely with fuel.
A professional installation by a shop familiar with your vehicle and it's fuel system is required. Always check for fuel leaks!


ECA-2 Analog Outputs
Ethanol content and temperature analog outputs are available as part of the ECA-2.  The flex fuel sensor does not provide these outputs.  We have created the ECA-2 to provide these outputs making use of E-85 easier with after market engine control modules and data logging systems.
