COBB Accessport V3 for 2013, 2014 and 2015 Focus STs and 2014-2015 Fiesta STs.
COBB's Accessport V3 is the best tuning option available for your 2013-2015 Focus ST or 2014-2015 Fiesta ST. This flexible ECU upgrade solution unlocks power hidden within the vehicle by replacing conservative factory settings with more aggressive calibrations. The Accessport V3 can provide off-the-shelf calibrations for most bolt-on modifications and it should be the last engine management solution you will ever need. Along with all the new viewable upgrades from the V2, the V3 also has more speed, more memory, more map storage, more live gauges and more troubleshooting help.
Choose from multiple gauge setups which include your choice of one gauge to six gauges. Scroll through tons of different display parameters to view the specific information important to you. Information can be displayed in metric or imperial units. A shift light can be set to the desired RPM and is plenty bright that a separate shift light isn't needed. Monitor all the parameters you want to view and customize each layout for the street, strip or track.
Measure 0-60 MPH time, 1/4 mile time or horsepower with a built-in dynamometer. An included trouble code reader allows you to diagnose problems on the fly without the need to stop at a garage. The most important aspect of the Accessport V3 is the ability to install different maps and quickly adjust tuning elements such as idle, timing, launch control and flat-foot shifting. Create your own custom maps for your Accessport V3 using Accesstuner Race. A complete OEM tuning table provides access to optimize your mapping for any set of modifications. Data logging is included so you can view engine vitals which can alert you to any changes that need to be made to your tune. If self-tuning isn't your thing, visit a local tuner in the COBB Professional Tuning Network to have a custom tune created and loaded onto your Accessport V3. You don't even need to physically visit a tuner if you don't want to. Use easy data logging and map loading on your Accessport V3 to have an e-tuning expert remotely custom tune your vehicle.
A few more exciting features COBB's Accessport V3 has to offer is an Burnout mode
Installation is extremely simple, fast and straight forward with easy-to-understand directions to guide you through setup. Initial setup matches the Accessport V3 to your vehicle modifications.

COBB tested a 2013 Focus ST with the following calibrations. Generally, the 87 and 91 octane calibrations run slightly lower boost, have a richer fuel curve and a less aggressive ignition advance map to help compensate for lower octane fuel blends and/or less than ideal atmospheric conditions. Maps designed for 93 octane are the most aggressive.

If I get a catback and downpipe to go along with my intake already installed, would I have to tune my focus st?
does this void factor warranties on a 2015 focus st?
Hello,... is the access port configurable in Celsius and in km/h ? and can you ship one to Belgium ? My car is a 2015 Focus ST .
I would like to purchase the cobb accessport V3, I have 2014 st from Canada. Is there anything specific I should know about which maps to download and is this port compatible with Mac computers? I have k/n airfilter and axle back MRT muffler delete?
I just got my tuner for my 2014 focus st and I did everything correct but it's not working. None of the gauges are working/ registering on the tuner and when I drive it i only have 5 pounds of boost max
Hi there, will this fit on a 2015 Ford Focus ST ? Thanks
hi I bought a cobb tuner / programmer from you guys awhile back for my 2014 fiesta st but now traded in my car and got a 2015 ford focus st can I still use my same tuner / programmer on this new car ? I wanted to ask before I tried ? thanks, derrick
Does the AP need to remain plugged in during vehicle operation after a Tune is loaded or can it be removed and plugged in again as desired?

The beauty of the COBB Accessport is the ease of use and the database that comes along with it. When you get your Accessport it gives you a link to their website where you can go on and download any map that you want. There are hundreds of maps to choose from covering pretty much any modification you want to do to your Focus ST. You plug in your computer and download the maps directly to your Accessport and plug in your OBD2 sensor to your Focus ST and install the tune. As usual, COBB gives you everything necessary including the tuner itself, multiple face plates, a cable for your computer, the OBD2 cable, a nice carrying case, as well as a mounting bracket for your dash.
Before we begin the installation of the Accessport you want to make sure if you're using another tuner you want to flash the vehicle back to stock first and that will unlock the other tuner and allow us to install the Accessport.
You're going to start the installation by taking the supplied OBD2 cable that comes with the Accessport, pull this cover down here and plug it in. Now take the other end of the plug, fish it up your dash, and plug it into your Accessport. It'll turn on automatically.
The first thing you notice about the Accessport, it's a nice high definition full color display. It's real easy to read, four buttons here at the bottom will run you through all the operations. The install is the main one but we'll click down to the check in one here. Here's your trouble shooting section. Click into that. You can read your codes, you can reset the computer, you can also kill the keep alive memory, which is nice if you're trying to delete a code you just can't get rid of. We're not worried about that now so we'll cancel this and go back to tuning stream.
Install tune is what we're looking to do so we're going to click on that. The next screen is going to come up and ask you what vehicle you're using. You want to make sure whatever you're programming with your Accessport is what comes up on the screen. In our case US 2014 Focus ST. We hit continue.
Basically here what you want to do is pick the file that best suits the performance mods you have done to your car. In our case we run 93 octane, we go to the stage I tune here. They do recommend putting a battery charger on it. It draws a decent amount of current when you're tuning with a tuner like this. If you have a battery charger use it. You definitely don't have to, but while you're tuning make sure your lights are off, radio is off, don't have anything else running at the same time.
At this point our Accessport is connecting to our computer to verify everything is correct before it starts the tune. Now it's saving the factory data from the computer. We're going to speed up all these processes. Each one is going to take usually a couple of minutes to go through, especially for your first tune. We don't want to make this a 25 minute video so we'll speed up this process here.
Now the Accessport is preparing the computer for the new tune. It's going to download. Now it's actually flashing our computer with the new file. This will be the longest part of the procedure, definitely going to take a few minutes for this to go through. The first time you program the car you want to give yourself, figure it's going to take 20 to 25 minutes to put the tune in.
When the flash is over the car is going to turn back on. Turn the ignition off and then we'll turn it on again. Okay to continue and there we go, our installation is successful. The check mark means everything is good to go. Tap the ignition button one more time to turn it off and our installation is finished with the tuner.
Now we start on our Ford Focus to make sure the tune went, everything runs like it's supposed to. Go back to your Accessport now and you'll notice you have different options. Before we just had tune and the check engine. Now you've got gauges, performance, there's an extra tune section there, as well as user tools. Take a closer look at gauges. Pretty much anything that runs off of the OBD2 port you can actually monitor now inside of your Accessport.
We set it up earlier for actual air fuel ratio, as well as boost. Those are the two most people are going to look at. We'll show you how to configure some others. You go onto the screen and hit the arrow at the top. Here you can change the layout and you can choose how many different things you want to monitor. We had it for six, we'll make it three to make it a lot easier to see. Now you can see we have our actual air/fuel ration our boost, and now we'll set up the bottom one here. Click down to it and hit the select button. You want to change the monitor and then go into all this stuff here and choose exactly what you want to see. We're going to make it actually do the charge air temp. Click on that. Now you can see we have our air/fuel ratio at the top, our boost in the middle, and the air temperature at the bottom. Again you've got tons of options here as far as you want to log and it's real time so you can use it on the car you're driving or you can actually log these for a Dyno tuning session if you wanted to, a very cool feature of the Accessport.
One more cool feature in here, we'll go back again to the arrow at the top for set up. Click into that and there's a shift light built in so we're going to set that up next. We're actually going to leave it at 4500 that way we can hit it without having to run the car red line, but normally you want to set your shift light up pretty much where you want to shift the car. To have a little more fun we'll set it at 5000. If you watch these lights here, once we hit 5,000 they will actually light up telling us to shift the car. Again, pretty cool feature.
Going back down to the main menu you see the stopwatch below the gauge. It actually has performance timers built into it. You have a 0 to 60 timer, as well as a quarter mile. If you want to try these out make sure you do it not on a public road. Find a big parking lot, abandoned air strip, somewhere else. It's a pretty cool feature that's built into the tuner.
Going back to the main menu again there's all your troubleshooting. This allows you to tune the vehicle and make adjustments and load different maps. Down the road you add an intercooler to make a different modification, get the new map for it, load it up to this, plug it into your tuner and download it to your Focus.
The last section down here is user tools where it says you can save and back up data. There is additional software available. If you did want to tune your car yourself you can buy the software through COBB through CJ Pony Parts and you can tune it yourself, again with a qualified user on a Dyno. You can see it's going to be tough to really tell the difference from one tuner to the other. You've got to get on the Dyno where you'll really be able to tell. I can say that so far it feels pretty good. The throttle response is really, really good. I almost swear the turbo sounds a little bit louder where it shouldn't, but there's a possibility the way the tune's being done we're making a little more boost as well.
We'll run up the gears a little bit and test out some of the gauges that come with the Accessport. That's cool, you can see the air/fuel when we get in the boost like it's supposed to, watch the boost jump like it's supposed to as well. The gauges are very cool. If you're trying to really keep an eye on what they're doing you want to log instead of actually watching them because they are kind of small. Putting the tuner where we have it makes it so you can look at it quickly while you're driving.
Judging off what we've seen on the Dyno when we're under full boost the air/fuel looks about right. So far so good. The Accessport is a great little tool to have for your Focus ST. Not only do you have access to hundreds of different performance maps, the gauge allows you to monitor any engine parameters that you want to, as well as data log them. You can also remove and troubleshoot any kind of engine codes and there's a few fun performance timers as well. If you're serious about performance for your Focus ST make sure you check out the Accessport from COBB.
