    Review & Installation Video

    Improves Power And Performance. Unlock the power hidden within your EcoBoost Mustang by replacing the conservative factory settings with a more aggressive calibration. From the factory, the manufacturer programs their vehicles to cater to the needs of the daily driver, not the performance enthusiast. But after loading a Cobb Accessport pre-configured "Off The Shelf" (OTS) tune, even a bone stock, unmodified Mustang will see Peak Gains of 24 RWHP / 87 RWTQ and Curve Gains of 47 RWHP / 88 RWTQ.

    Performance Calculator. Measuring your Mustang's 0-60mph ET, 60 foot, 1/4 Mile ET and Trap Speed has never been easier. The Accessport accurately estimates your vehicle's performance with the help of a built-in dynamometer. This allows you to measure performance gains before and after vehicle modifications.

    Virtual Gauges and Shift Light. Using the live data from the OBD-II Diagnostic port the Accessport can be used as a Virtual Gauge to monitor from one to six different parameters at once in real time. Users can even set custom RPM warning lights for perfect shifts every time.

    Data Logging and Monitoring. With a full color high resolution LCD display, the Accessport V3 Tuner makes it easy to read and record multiple data channels simultaneously for in-depth evaluation of engine performance. The Accessport can store up to 10 hours of data directly from your vehicle's PCM/ECM.

    Diagnostics. The Cobb Accessport V3 Tuner can also be used as a diagnostic code reader. Save yourself hundreds of dollars each year by reading and clearing your own trouble codes rather than paying a dealer to do the same. Its as easy as a few simple steps.

    Easy To Load; Easy To Restore. When you load a tune on your EcoBoost Mustang, the Accessport tuner automatically stores your vehicle's factory settings. To return the vehicle to its factory settings, just plug the Accessport back in, select the option to restore the factory settings, and you're done. The Accessport can hold up to 100 different tunes

    Application. The Cobb Accessport V3 Tuner is specially designed to fit the 2015-2018 EcoBoost Mustang's equipped with the turbocharged 2.3L Inline 4-cylinder engine.

        I have a 2018 mustang which has the “mode” toggle switch that can switch it from normal to sport, track, drag etc. Once having the tune set up I do I need to use the mode switch at all? For example if I had the tuner on eco mode but I switch to sport mode on my car would it damage anything?

        Can i apply the stage 3 settings if I have a mishimoto M Line intercooler, MBRP catback race exhaust 3'' in. downpipe, and a roush cold air intake?

        • Yes, you will be able to do that with those mods.

        Helpful (0)

        Would I have to keep the tuner plugged in at all times even after I install the tune or is it just a one time plug in?

        • Once the tune is downloaded you can unplug the tuner.

        Hi Appreciate your last answer that I can "access" the ECU, but can I change the oil pressure switch setting from switch to sensor?

            2015 EcoBoost

            I love how it doesn't fall on it's face at higher RPM's now and having a 2 step is too much fun, I only wish it could be turned on with the cc buttons instead of having to use the AP. My Miles to Empty also dropped from 320mi till E to 246mi to E w/91 octane stage 1 tune. I won't go back to stock tune unless it's having warranty work done, it's a completely different car now..

            It’s amazing to know this easy to use tool can load software that really changes your car for the better, makes you wonder why the factory, or the ford performance tune, are so conservative.

            Cobb does not stray from their level of perfection with this device. Absolutely does as advertised on my 2018 Mustang Ecoboost. If you're considering making a purchase, this one certainly does as advertised.

            Torque increased drastically

            This accessport REALLY changes the way the 2.3L performs. I'm talking the amount of torque you feel in higher gears at lowers speeds and lower rpms when you get on it really makes the difference. Instead of having to downshift, you can punch it in 3rd gear at 25 mph and just feel how it lays into the power band increase. It's not just a tune though, the additional features for when you let your irresponsible friend drive you mustang such as "valet mode" and "anti theft mode" make it fun to prank your friends when they think they're going to "lay into it" or "take it for a spin around the parking lot/around the neighborhood" when you leave the keys in it. This thing is amazing.

            Amazing HP gains

            First off my initial thoughts after installing the accessport with the ots stage 1 91 tune is the change of the shift points. This is an improvement from stock and makes a huge difference. Then there's the HP and Torque gains that are very noticeable. The cobb accessport is a great tool to have and gives you the opportunity and range to totally change your performance whether it be off the shelf or custom tuned from someone like Adam (tune )

            Best Ecoboost Tuner.

            I went straight for the stage 2 because I already had bolt ons...took a couple of miles for tune to fully kick in. When it does you know instantly. Ran a 13.4 in the 1/4 at 110 with some simple bolt ons. 10/10

            Pulls all the way through the gears, gave me an extra 2 mpg(tracked with trips), and the valet mode in Miami is more then useful! Love it, and the fact that you can customize your loading screen is awesome!

            Nice Power Increase!

            I installed this with an AEM drop in filter in the stock air box. Used the stage 1 OTS tune for 93 octane and it really woke up my daily driver Ecoboost Mustang with 10 spd auto. Most noticeable is the low end torque increase, with a mild increase to high RPM pull. Also seems to have more turbo noise. MPG has dropped by about 2 but that might be because I’m into the gas more! Loving it! FYI, if you’re installing this on a non PP ‘stang, go ahead and update the firmware on this device before you attempt it! It might save you some frustration and a phone call to Cobb.

            5 stars if you have newer than 2018

            The device is great and provides dozens of more data points than any SCT device you will buy. This really gives you a leg up for determining what your care is doing and tuning capabilities. With that said, all of the special functionality (Launch Control, Bump Box, Burnout Mode) are not present for a 2018 model at the time of this writing. Unfortunately, I did not know this until afterwards when reading deep into their documentation. Hopefully a firmware update introduces these features SOON as its part of the reason why I switched to this device from an SCT device. Performance gain all depends on the tune you use. I cannot vouch for the canned tunes that come with the device as I have a list of custom parts on my EB and I am using a custom tuner for my files. Performance gains are in line with tunes I received on the SCT device. In fact, I would say they are more reliable due to the data points this device provides my tuner.

            Paired mine with a custom tune from a well known ecboboost tuner. Well worth it. Even the canned tunes are worth it. But a custom tune with supporting mods changes the car in the best ways.

            Joined the COBB AP v3 Family!

            Prior to buying my COBB AP, I had my car tuned with DiabloSport. Low end torque with that tune seemed higher than the COBB Stage 1 I'm running now, but the way the car pulls smoothly through the entire power band more than makes up for that. Plus, with COBB I get multiple OTS tunes, each designed around specific mods and all of them are free.

            It is Great and Easy to use. It conveniently designed map slots into the cruise control so you don’t have to keep the Accessport in the car. I would definitely recommend this for anyone who has the specified mods that Cobb adheres tuning to. I didn’t have to buy a personal tune.
