Simple ECU flashing with gauge package! The new in-cabin mountable Accessport V3 has a large, full color, higher resolution screen which allows you to monitor up to six parameters in real time. Fully customizable from the look (multiple bezel colors), layout (set up race, street, or dyno gauge clusters), and mounting options (choose from 1,000s of standard vehicle mounts). And what's looks without brains? More processing power, memory, and storage to flash faster while saving all of your maps and logs. This is your new Accessport.

Warning! Installation of this Accessport over anything other than OEM or COBB software may result in ECU/TCU failure. Please contact COBB Support if you have any questions.


The Accessport is the world's best selling, most flexible, and easiest to use ECU upgrade solution for your Ford. Unlock power hidden within the vehicle by replacing conservative factory settings with more aggressive calibrations. Follow our staged upgrade path with pre-loaded Off The Shelf (OTS) maps or use custom mapping for any modification level. It's the last engine management solution you'll ever need.

Stage1 91* Gains:
Peak HP: +11.33% / Max HP +28.14%. Peak TQ: +18.02% / Max TQ +27.92%

Stage1 93 Gains:
Peak HP: +11.93% / Max HP +29.62% Peak TQ: +19.92% / Max TQ +29.39%

Stage2 91* Gains:
Peak HP: +21.81% / Max HP +36.69%. Peak TQ: +18.95% / Max TQ +39.84%

Stage2 93 Gains:
Peak HP: +24.23% / Max HP +44.10% Peak TQ: +20.02% / Max TQ +44.26%

*91 Oct = 95 RON | 93 Oct = 98 RON. Peak gains are measured as the difference between the highest points of the two plots. *Largest gains are measured as the largest gain at any single point between the two plots. Results may vary.

Generally speaking, 91 octane calibrations have a richer fuel curve, and a less aggressive ignition advance map to help compensate for lower octane fuel blends such as those found in Arizona, California, and Nevada; and/or less than ideal atmospheric conditions. The maps designed for 93 octane are the most aggressive. *91 and 93 octane results are compared against a 93 octane fuel baseline. Your 91 octane results may be higher than listed above; as a baseline of 91 octane fuel may read lower than our 93 octane baseline. 87 octane results compared against an 87 octane fuel baseline. Your 87 octane results may be higher than listed above if a blend of higher octane fuel is present.

Ford Focus RS Accessport V3 is rated 4.9 out of 5 by 16.
Rated 5 out of 5 by from 2017 Focus RS has awaken!! I had an Access port for my 2014 Focus ST and it was the best upgrade for the money I bought, it was a totally different car. Fast forward 3 years and I finally get an RS. The car of my dreams. I knew the first thing I had to do, Filter and Accessport. Let's just say the car felt like someone poked it with a stick and it was finally awake. Car was quick before but the Stage 1 off the shelf tune put the car where it needed to be. Amazing product! Can't go wrong with this upgrade, hands down best bang for your buck! Nothing comes close.

Rated 5 out of 5 by from Excellent product Like RS Huey, I have previous experience with the V3 Accessport so I knew installation would be simple. Installed the stage 1 93 octane tune. Car is stock aside from a CP-e intake. First thing I noticed was a great improvement in throttle response in Normal mode where the go pedal previously felt like a sponge. It becomes even more sensitive in Sport. Torque gets a noticeable increase and the car pulls much more strongly between ~4-6k. Looking forward to an RS turbo-back, intercooler, and supporting tunes from Cobb. Easy to use, great quality, and awesome performance!

Rated 5 out of 5 by from Gotta dig the Accessport Just installed the Accessport on a 2016 Focus RS. Had the Accessport for 2015 STi so I knew it is a great product! Just like the STi, the RS Accessport is easy to install and I instantly noticed the improved torque and responsiveness in Normal and Sport mode. Great product!

Rated 5 out of 5 by from Great Product, no doubts about it. It's the first time that I own a product like this while in the past I've tuned my cars with direct ECU Tuning/Programming. I fall completely in love with the Accessport within seconds. The data-logging capacities (for a nerd like me) are impressive. The wasy installation/configuration for someone not as handy with technologies or mecanics, it's just exceptional. Pros: - Mostly Everything, but the ability to store different ECU maps is the best of the features. - Datalogging. Lot's of parameters, really fast samples (got 15hz+ with a huge list of monitors) - Easy Install/Uninstall. - Freedom to choose form any e-Tuners out there. Cons: (I'm being nitpicking!) - Maybe screen resolution could be improved - TouchScreen also would be supreme to have Conclusion: BUY it, worth every penny.

Rated 5 out of 5 by from awesome performance for the price needed a tuner to adjust for mods.. accessport is the tool for the job.. Cobb's OTS map re-enabled my "eco shift lights" that tell me when i need to shift for best fuel economy.. somewhat annoying since Ford dealer turned it off for me.. really wish the the handheld options could modify vehicle features like that light, the auto start/stop, pops and burbles, etc.. without having to have access tuner software that now costs money to obtain.

Rated 5 out of 5 by from Great upgrade for the already amazing RS Just re-entered the 4 car turbo world after years. My last car was a 2010 WRX STI which I poured 6K into upgrading the turbo, exhaust, injectors and ECU. The stock RS was already on par with my modified STI. Adding the COBB Accessport, has made the RS an even more FUN car. Absolute raw power may be higher in more expensive vehicles, but the FUN factor this car+Cobb deliver is more than worth it.

Rated 5 out of 5 by from Excellent as always What is there to say that hasn't already to be said. Another excellent product form COBB.

Rated 5 out of 5 by from Great Upgrade! The Cobb AP is worth every penny--I sent my Fiesta ST AP in for relicensing and Matthew, Charles, and Ryan walked me through the process and kept me updated. Quick turnaround time and shipping. My RS feels like it came alive with the Stage 1 OTS tune--highly recommend it!
