item:PSR/Raceworks/Zeitronix Flex Fuel Kit for Subaru WRX 01-14/STI 01-21 (PSR Fuel Setup)

Pro Speed Racing now offer flex fuel packages including the Zeitronix ECA2 kit with quality Raceworks hose fittings. Also included is the PSR Plug and Play ECA Harness which deletes the rear O2 sensor and uses its ECU input for easy setup. (Tuning required). This kit suits the with aftermarket fuel pressure regulators.

The Zeitronix ECA2 (Ethanol Content Analyser) kit includes a Flow Through Flex Fuel Sensor, the Ethanol Content Analyser module and an ECA Harness. E85 has the equivalent octane rating of 105 or higher octane fuel.  Higher octane fuel is more resistant to knock allowing for more aggressive ignition timing, higher compression and increased engine power over gasoline itself. 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.

The Zeitronix Ethanol Content Analyser helps you get the most out of your engine and fuel by measuring the actual ethanol content so the ECU can run the vehicle safely no matter the ethanol content*. (*Tuning required)

ECA2 Features:

• 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). Check out the gallery for gauge installation pictures.
• 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 dimensions: 3" x 2" x 1" (76mm x 50mm x 25mm)
• Made in the USA!
