PSR/Raceworks/Zeitronix Flex Fuel Kit - Subaru BRZ/Toyota 86

Pro Speed Racing now offer flex fuel packages including the Zeitronix ECA2 kit with quality Raceworks 6AN teflon hose and 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).

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)

If you have a deadline to meet, please confirm that we have stock ready for dispatch to avoid disappointment!

This kit incorporates the Raceworks 200-Series E85 safe braided hose in either stainless steel braid or black braid. Raceworks 200 Series Teflon Braided Hose is constructed from a PTFE (Teflon) inner tube that is compatible with all fuels, oils, nitrous including brake and clutch fluids. The PTFE (Teflon) tube is covered by a stainless steel outer cover that is durable, and resistant to abrasion and expansion. The Raceworks 200 Series Hose is the best option for use on fuel systems as it won’t allow the permeation of fuel smell, and has the highest pressure and temperature rating in the range of Raceworks hoses.

Raceworks 200/220 Series Hose Ends are all manufactured from 6061 T6 grade billet aluminium. All Raceworks hose ends are hardcoat anodised for maximum protection, and full flow to provide uninhibited fluid movement. Female swivel hose end ensures ease of fitment once 200 Series Hose has been connected. All Raceworks products come with a 2 year warranty.
