Honda Civic Type R FK8 Accessport Support

Now Introducing…

The Honda Civic Type R is arguably one of the most recognizable and modified vehicles in the automotive enthusiast market and starting today, you’ll be able to pair it with the world’s easiest and best selling tuning solution, the COBB Accessport! With Honda fully embracing the light that is turbocharged engines in the US market, it only makes sense that the Accessport returns to the Honda to take full advantage of the new K20C1 powerplant and we’ve done just that with the AP3-HON-001. The best news is that all of the power increases are completely DIY and can be done anywhere, anytime, without any additional fees or unlock purchases required. One solution and done!

It’s the last engine management solution you’ll ever need.  Installation takes just 6 minutes from the comfort of your own garage or driveway.  Simply connect the included OBDII cable to your Civic Type R’s OBDII port and follow intuitive the on-screen instructions. And for those of you with MY20/21 vehicles, worry not as you’re able to do the “jailbreak” using our COBB Unlock Box that is included in every Accessport kit! Honda Civic FK8 Type R Accessport

Off The Shelf Maps & Power Gains

Included in the Accessport, also available for download on our website, are our COBB Off The Shelf (OTS) Maps.  These files are generated by our COBB Calibration Team for otherwise stock cars.  Components like replacement air filters for the stock airbox and exhaust components that retain factory catalytic converters are safe to use with these OTS Maps. The Stage0 file does not increase power as it retains all factory calibration data but provides the ability to utilize all of the other Accessport functions, such as data monitoring and logging.

Our Stage 1 files are aimed at really taking advantage of what Honda has left on the table.  With increased boost pressure and more aggressive timing/fueling curves, and much more, we are able to produce a significant increase in both low end torque as well as top end power.

  • Stage0 v100
  • Stage1 91 OCT or 95 RON v100
  • Stage1 93 OCT or 98 RON v100

In the clear, no matter where you live

The COBB Accessport for the 2017-2021 Honda Civic Type R (AP3-HON-001) allows you to flash and tune without worry as our device and all calibrations come with coverage via an executive order from CARB (D-660-174). This means you don’t need to duck and dodge the fuzz or even need to uninstall before going in for any smog checks. We’ve got you completely covered at full power, no secondary neutered calibration.

    • We do plan to offer support for additional vehicles in the future. What specific Civic trim are you interested in tuning?


  1. When running stock airbox and exhaust and just using pump 91 gas. Do we have to dyno the car for stage 1 OTS calibration to use? or just plug and good to drive immediately?

    • No need to put the car on the dyno unless you simply want before and after charts. Just plug the Accessport into the car, flash the Stage1 91 map, and you are good to go!


  2. I notice there are a lot of features missing on the fk8 type r ap like auto shut off, anti theft mode, ffs are these features going to be added in later on throigh a update?

    • Hey there! We are currently working on our first iteration of COBB Custom Features (CCF) for the FK8 which will include Launch Control and Flat Foot Shifting. Keep an eye out for that in the next month or so. Our software team is ramping up to implement a fix for the Auto On/Off feature that is currently broken for ALL new Accessports, I don’t have an ETA for that at the moment. Both of those will be implemented with a simple, free firmware update to the Accessport when available. Right now we do not have plans to offer an Anti-Theft Map but that can always change with enough demand!


  3. I currently own the fk8 tuner and I’m utilizing the off the shelf map. Can I legally get the car tuned at a shop now too?

    Mine didn’t come with a carb sticker, do I need one?

    • Hey there! You can absolutely have the car custom tuned by one of our Protuners with the Accessport you already own, no need for additional hardware or anything. The legal side would be a question for the Protuner creating the tune as they would need to go through the same emissions compliance testing our COBB OTS Maps underwent. Please contact our Customer Service team at 1-866-922-3059 or [email protected] for a CARB sticker.
