Features & Product Details

The COBB Tuning Flex Fuel and Ethanol Sensor Kit will allow users to safely convert their fuel systems to properly run ethanol. Why is this important? Because gas stations that supply ethanol all run different ethanol percentages. It is not safe to run the same boost level on ethanol that has a 70% value when compared to ethanol that has a 40% value. 

This is a complete plug and play system that allows users to run ethanol without compromising the factory fuel compensations. Once installed, you can monitor the ethanol content through the Accessport. Included in this kit will be a billet aluminum converter case, OEM quality electrical and fuel line connectors, as well as hardware to make this kit ready for installation. 

Please note that this kit requires custom tuning for proper use. 

FITMENT NOTE: Manual transmission only, CVT transmission equipped models are NOT supported.

Easy install everything is labeled it’s very straightforward. DO NOT install before tune if you don’t have TGV deletes even if you are just going to run pump gas, you’ll get a CEL because the TGV sensor changes the ECU signal to read ethanol , unless you have TGV deletes already then just install without using ethanol,

QUESTIONS & ANSWERS

  • Q: Flex fuel   awd.wrx6 months ago

    If I have a flex fuel kit and tune, can I run full 91/93 if I have to, or does it always have to be a blend?
    • 0 of 0 people found the following answer helpful

      A:  you can run normal pump gas for sure. Anytime you change fuel's make sure you take it easy on the car for a bit, that way the sensor has time to register that there is different fuel in the car and can adjust the tune. Also make sure your tune was for true "flex" meaning if you got a custom tune, and they only tuned the car for Ethanol, normal pump wont work, but if you are running an off the shelf cobb flex fuel tune, you'll be fine :)

  • Q: Fuel Injectors   Alex3 years ago

    You mention that in order for this to work, you need aftermarket full injectors. It doesn’t appear you sell these for the 15 WRX. What would you recommend using?
    • 2 of 2 people found the following answer helpful

      A:  With the 2015+ WRX being Direct Injection, you wouldn't need to upgrade the injectors.

  • Q: Additional Parts required?  Ryan3 years ago

    I've seen elsewhere that you'll need to but better injectors and fuel pump? Is this true? Also, once its installed on your car and has been tuned will the tuner tell you how much E85 to add to your pump gas during your regular fill-ups?
    • 0 of 0 people found the following answer helpful

      A:  At the time there are not currently better injectors for the vehicle and direct injection should be able to handle the additional 30-35% required for ethanol. This kit with a tune should be all you need to start running E85 or E30/E40. If you notice issues with fuel pressure it can be related to the HPFP not being properly lubricated which can be fixed by switching back to regular 91/93 gas.

  • Q: Flex Fuel  fliptriphippie 3 years ago

    I'm confused as to what exactly this does. Does this allow you to add a tune to your engine through Accessport that let's you run flex fuel without any other modifications? If not please explain to me why exactly this does?..
    • 0 of 0 people found the following answer helpful

      A:  The flex-fuel kit will allow you to run E30/E40/E85 and your regular octane gas (91 or 93) together at the same time. Just because you get this kit does not mean you can run both at the same time right away. You will need a custom tune for the flex-fuel kit. All this does is read how much ethanol is in your system and then adds or reduce the necessary amount of fuel to ensure proper combustion. Running full E85 can cause lubrication issues with the HPFP, so if you have this and are running high ethanol content fuel like E85, then it may need to be cleaned and relubricated. You can do this by going back to regular gasoline and it should correct fuel pressure issues.
