CAN Gateway for Subaru

COMING SOON, an all new Flex Fuel solution for Subaru.


  • Supports plug and play integration with a vehicle’s CAN bus, providing a seamless solution for reading and reacting to sensor data from multiple sources that can then be utilized by the ECU for tuning.
  • Allows for adding aftermarket sensor data, including flex fuel, without interfering with existing OE sensor inputs.
  • Billet aluminum, CNC machined case tested to OE level environmental standards.
  • Utilizes proprietary, modular harnesses with motorsport grade, weather-sealed connections to vehicle and sensors. 
  • Compatible with a wide range of sensors and inputs, to support an expanding list of years, makes, and models.
  • Mounts to a vehicle specific bracket using high grade stainless steel hardware.
  • Capable of supporting up to 6 digital or analog inputs

What the heck is CAN?  Watch our CQC below for a quick explanation!

For those who may not recall, this is not our first CAN Gateway.  Our Nissan GT-R CAN Gateway application was launched back in 2019.  The COBB CAN Gateway allows for seamless integration of Flex Fuel tuning without needing to hijack important OEM sensor inputs.

  1. to support an expanding list of years, makes, and models. does that mean that’s its going to work with the new 22-later vb wrx? please say yes

  2. Will this help remidy the issue of EPA regulations and loosing alot of flex fuel and tuning support with access ports on the subarus?

    I Purchased the stage one plus package for my 2009 Forester xt with the intentions of getting a flex fuel kit eventualy, it was the whole reason I purchased the Accessport over other brands.

  3. I currently have a pregreen speed flex fuel sensor and tune. My sensors brain died, my car has been stuck in limp mode for months due to this issue. Will this new one be plug and play and my current tune work?

    • You will need to have the car re-tuned with updated software in order to utilize the new flex fuel solution once it is made available.


    • A COBB1 code with our original and NexGen flex fuel kits can indicate a number of different issues including the occasional module failure. This system is completely new with no shared components other than the ethanol content sensors themselves.


  4. I know this was targeted for a mid January release you had said previously, how’s it looking? Can we expect this anytime soon??

    • We’re nearing the completion on the development side and in the midst of emissions testing. It doesn’t look like January is in the cards, we are trending more towards a mid-February release at this point.


  5. Idk if this is relevant to this, but will this allow for GESI downpipes to be tuned without CEL going off. I have a 2021 STI and read around that downpipes throw CEL on and can’t be turned off by tuners.

    • We will not be introducing the ability to toggle off DTCs related to catalyst efficiency. The 2019+ STIs utilize a different manner to determine catalyst efficiency and are more likely to fail the car’s onboard test, causing a DTC. In our experience, there are very few, if any, downpipes available on the market that will not cause a DTC on those cars.


  6. I need to update my non-compliant one when this is released. Will Cobb sell the harness separate from the sensor again?

    • We do not plan to offer that type of kit for this application. The ONLY reusable component is the ethanol sensor itself.
