Cobb CAN Flex Fuel Kit 2015-2021 WRX
Take advantage of E85 the right way with Flex Fuel. This kit allows the ECU to monitor ethanol content on the fly so the tune can automatically adjust for any blend of ethanol. Once fully tuned, you can run any mixture of gasoline and ethanol safely. No more worrying about how much ethanol you are getting from a particular station or when the seasons change.
This plug and play CAN Ethanol Sensor Kit is the heart of our Flex Fuel product offering. It consists of an ethanol content sensor with mounting bracket, fuel lines, and a plug-and-play wiring harness to bring it all together.
The OE quality ethanol content sensor is secured to a bespoke powder coated aluminum bracket. Fuel is then fed to and from the sensor with pre-made fuel line with OE quick disconnect.
Tying everything together is a custom, easy to install, plug-and-play wiring harness. Utilizing OE quality wiring and connectors makes adding NexGen Flex Fuel on your supported Subaru both quick and reliable.
Fuel Pressure Add On
This optional add-on allows the ECU to monitor your low side fuel pressure. This can be helpful to catch and diagnose any low-side fuel pressure issues and is recommended to add on.
Fuel Pump Add On
For running high blends of ethanol, we recommend upgrading your In Tank low pressure pump if you do not already have one. This option will add a Deatschwerks DW300c pump to supply the extra needed fuel to the high pressure pump.
