Zeitronix Ethanol Content Analyzer 2 with Flex Fuel Sensor

• Two 0-5 V analog outputs: Ethanol % and Fuel Temperature for use with ECUs, data logging and engine management systems.
• Connecting harness to Zeitronix Flow Through FLEX Fuel Sensor is included. Harness length is 8 ft (2.4m)
• Optional real time E% Ethanol Content Gauge.
  The E%  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 E% 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)..
  The E% Gauge plugs into the ECA-2 GAUGE port. Power and serial data is supplied directly through the single connection - there are no additional +12V or ground wires. The E% Gauge cable length is 5 ft (1.5m).
  ECA-2 is required for E% Gauge operation.
• A flex fuel sensor is required.  The ECA-2 is compatible with standard OEM sensors used in most GM vehicles with the flex fuel insignia or which run on E85. ECA-2 Kit includes Zeitronix Flex Fuel Sensor.
• ECA-2 dimensions: 3" x 2" x 1" (76mm x 50mm x 25mm)
