The second generation GT1R Flex Fuel Kit has been improved by being both completely plug and play for all R35 GTR models of the year, as well as moving the sensor to the pressure side of the system.
The sensor on the pressure side of the system gives more consistent readings when fuel backflow is minimal (when you're maxing out the fuel pumps).
We've also updated the wiring and now offer a plug and play wiring harness. As with all of our wiring harnesses, we use Race Spec, the best in the business. Our wiring harness comes assembled with Mil Spec Tefzel wire, Raychem DR-25 heat shrink tubing, and new connectors for a durable and clean PNP installation.
The Flex Fuel Converter Box converts the ethanol sensor's digital signal into a 0-5V signal that the stock ECU requires. With this converter the output is 0.5V for 0% ethanol and 4.5V for 100% ethanol.
No display is used with this kit as both Cobb and EcuTek allow the user to display the ethanol content in their own way.
The complete kit includes all plumbing with high quality Redhorse Performance ethanol compatible tubing and crimped tubing ends, the ethanol level sensor and bracket, and the PNP wiring harness.
We offer kits for the stock fuel line or for aftermarket fuel lines. The stock fuel line kit includes a line adapter to convert the line inlet to AN thread. If you are using aftermarket rails, you must specify what size rail is (6AN ORB or 8AN ORB).
