Product Description

COBB Accessport V3 for 2013, 2014, 2015 and 2016 Focus STs and 2014, 2015 and 2016 Fiesta STs.

COBB's Accessport V3 is the best tuning option available for your 2013-2016 Focus ST or 2014-2016 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. The on/off switch allows you to turn off the programmer so the battery doesn't die. An automatic dimmer brightens and dims the screen depending on day or night.

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.

COBB Accessport V3 Focus ST 2013-2016/Fiesta ST 2014-2016 is rated 4.9032 out of 5 by 31.
Rated 5 out of 5 by from Engineering excellence. The Accessport V3 is a fantastic product. Having been a Mazdaspeed 3 owner prior to owning my Focus ST, I'd had experience in using the Cobb Accessport V2. Upgrading to the V3 for the Focus was an excellent decision. The V3 is precisely the product that I wanted from Cobb. The screen is beautiful, the features plentiful, and the power gains so noticeable. Additionally, Cobb has a world class staff, and genuinely provides a product that you can feel confident in installing on your expensive vehicles. My Focus is a daily driver, and now, it drives even smoother than it did off of the showroom floor. Lastly, I greatly enjoy pulling away from cars that cost twice as much. It's always a treat.

Rated 5 out of 5 by from There's nothing like the Accessport I installed the Accessport on my 2014 Fiesta ST a few weeks ago and can give a little bit of feedback on what to expect. After a few track days and a dozen autox's, it doesn't give you a ton of HP, but the torque gains are noticeable. Much smoother acceleration (Stage 1, 91), and thankfully removes the boost restriction in first and second gears. The AP is really unrivaled when it comes to a truly programmable and adjustable engine management product. There really is nothing like it. Highly recommended to any car guy that Cobb supports.

Rated 5 out of 5 by from All I can say is wow! I am thoroughly pleased with this product, the programmers at Cobb did an amazing job with the OTS maps. I have a 93 octane stage 1 map on my focus ST, and now I'm perplexed as to why this car could not come like this from the factory. The tune is not overly aggressive and changes the throttle mapping to a much more usable layout. The gas pedal is much more linear in its power delivery, it really doesn't even feel like a turbocharged car anymore, this is alone worth the cost of the AP. Surprisingly my CBE suffers from less drone somehow with the tune. Also the AP comes with customizable gauges, and 0-60 and 1/4 mile timers, which have proved to be very accurate. Gas mileage penalties are negligible. The stock map just seems lazy now. I recommend upgrading the rmm or you will get insane wheel hop. Great product.

Rated 5 out of 5 by from Great daily driven add on !! Needed something quick and easy to instal to accommodate some upgrades that were done on a Fiesta ST. Easy installation and setup. Flashing is quick and efficient. Economy and valet mode are also pretty cool if your going on a long trip or actually valet your vehicle. All in all I'm completely satisfied with Cobb tuning products and functionality. Thanks Cobb In Texas !!

Rated 5 out of 5 by from Simple, easy to use. - Fiesta ST The Accessport V3 with COBB tuning is the first performance item one should purchase for their future Fiesta ST. The product unlocks the potential for the car. And the OTS maps offer a great starting point for tuning. As you move up the Stages of modification, the OTS maps work well with the performance parts that you have made to the car. On top of that. I especially love the built in code reader, and real time gauge functions. Up to 6 parameters can be monitored and displayed at a time. This is essential, and a very nice feature. Even if I don't plan on going any higher than a OTS Stage 1 tune. I like how I can see what exactly is going on with the car in real time. And you can add a shift light function built into the display! Unplug the unit, remove the OBDII cord, and now your car is a pure sleeper. Nothing to give away what you actually have under the hood! Extremely happy with my first performance part purchase for my 2014 Ford Fiesta ST.

Rated 5 out of 5 by from Well worth the money! The Accessport would not initially recognize the vehicle. Called tech support and got Accessport Manager firmware downloaded to my home computer. Updated unit from there with ease and then flashed car with no problems. Great upgrade for the money on my 2015 Fiesta ST. Much stronger low end torque and pull through the rev range.

Rated 5 out of 5 by from Awesome Upgrade I just got my Cobb Accessport today and installed to my 2015 Ford Focus ST. I installed Stage 1 91 V312 map to my car. What a difference from stock to Stage 1 you can really feel the difference in torque. Stage 1 V312 map has the most torque yet. I highly recommend the Accessport it's worth it.
Date published: 2015-10-21
Rated 5 out of 5 by from ACCESSPORT I have used SCT, Diablosport, and the COBB Accessport. By far , the COBB IS the most user friendly. The interface and software is so much simpler to use and works great. Reflashes are also much faster. It is pricey but COBB's support with maps and updates makes it worth it.

I am considering buying accessport and was wondering if they already had tunes or "maps" already on the system or if it is something that I have to purchase after buying this?

Asked by: HunterLee
They include tunes/maps for your typical modifications. Even if you are stock, the device will write an improved tune file for you.

Could the dealership find out you tuned your vehicle if you flash it back to stock configurations, should any power train warranty issues arise?  I want one of these, but I don't want to jeopardize my warranty.

I have a 2013 Focus ST with a few mods, Cobb cold air Intake, Ford Racing air intake (just the snorkel), Scorpion CAT back, along with a few cosmetic changes. I use 93 octane, if I were to purchase the V3 any Map suggestions for my ST, Stage 1-3?

Asked by: Bob5000
I would recommend their Stage 1 Map. You can always contact Cobb directly and see if it would be ok to run a more aggressive Map with your modifications.

Good Morning. Does this tuner need to be constatly connected to the vehicle after programming a map, or does disconnecting it remove the program? Will this also remove the boost restriction in 1st and 2nd gear? I own a 2015 Ford Fiesta ST.

Asked by: Ritzmannb
No, it does NOT need to be constantly connected to the vehicle. But it can be if you choose to. Once you upload the calibration, the Accessport can be disconnected. The new COBB tune will completely change your Fiesta ST for the better, adjusting almost every aspect and increasing overall driveability. I see that you are in Germany, keep in mind that without the vendor supplying any information regarding fitment for non-US Spec cars and CJ's not having a car to test parts on, we cannot confirm this part working on your non-US Spec vehicles.

COBB Accessport V3 Focus ST 2013-2016/Fiesta ST 2014-2016 Video Transcript
By Bill Tumas: Performance wise so far we've installed a COBB cold air intake and a Borla exhaust system on our Focus ST. Right now we're using SCT's 93 octane base file for tuning and have seen some pretty good gains out of it. The only drawback to the base file is it's actually designed for a Dyno tune so you want to put the car on the Dyno and then modify the tune for maximum performance. If you're changing as many parts as we're planning on changing this doesn't make much sense. Today we're looking at another way of tuning, which is the Accessport from COBB.

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.
