COBB Accessport V3 - Ford Mustang 2.3 EcoBoost
The COBB Accessport really is a firm favourite here and not just because it means the end user can install their own calibrations at home, but because the handset transforms the vehicle by adding the option of up to six gauges on screen at any time out of a list of literally hundreds. It also gives you data-logging and diagnostic facilities for reading codes and resetting KAM etc. The Accessport comes with COBB's OTS tunes built in and ready to go. Just choose the one that suits your supporting mods and away you go.
But for us, the real power of Accessport comes when you also purchase an MSD Protune to go with it....
We utilise the power of Accessport fully to bring you our own tried and tested calibrations that not only retain factory driveability but also bring in some additional awesome features, including the optional MSD Multimaps, which brings the ability to swap between MSD power stages in seconds (EG: Swop between 95RON safe, Enhanced Standard, 345PS, live with the engine still running) using just the vehicles cruise control buttons (See videos tab below) and we also build into every MSD protune a minimum of two custom E-tunes, this means that once you have installed the calibration and got used to the extra power, we will then custom tune your car for you remotely to get the most from your supporting mods and fuel, remotely via emails, at no extra charge!
The COBB Accessport and MSD custom tuning are a match made in heaven!

Further details
- Power Level / Hardware Requirements
MSD 340+ (510NM / 340+PS)
This calibration works perfectly on a totally standard car and lifts the power restrictions from within the ECU, further enhancing the power output to 510NM and 340PS.
The factory rev limit and all the temperature protection features of the management system are retained, whilst the relevant fuel, spark and load tables are further optimised to achieve this new power output.
Rest assured that if your coolant, oil, exhaust or charge temperatures get too high, the ECU will actively lower your available throttle opening and boost pressures as well as add fuel to cool things down until such time as the temperatures are back within safety parameters. Full LSPI / Knock control is retained at factory safety levels. Some tuners remove all this capability in order to achieve their power - Take care out there.
- Driving Enhancements
All of our Accessport MSD calibrations come with the following awesome feature's enabled:
Return to standard tune yourself. (FOC)
The Accessport enables you to return the original ECU calibration back to the vehicle at the click of a button. Selecting "Uninstall Accessport" will remove any tune applied by it and return the vehicle to its original tune and place your custom tune back on the Accessport, leaving it in an as new condition ready to be sold on. This can be done yourself at home with no tuner input required.Flat foot shifting: (FOC)
Enabled on all our calibrations, this features allows the accelerator pedal to stay fully depressed while shifting gears. The use of the clutch pedal will still be necessary, but keeping the accelerator pedal fully depressed between shifts allows for the turbo to stay spooled between gears, so you can concentrate on the fastest gear-shift and let MSD take care of the engine speed.No hassle launch control: (FOC)
No more entering menus in a hurry! With our calibrations the process of getting into launch mode is simply having the clutch pedal and accelerator pedal depressed fully. The engine speed will quickly raise to the determined RPM set in the calibration file. (Adjustable on request)5-way launch control set-points: (FOC)
This feature enables users to switch between 5 different launch control set points on the fly. You can use the factory cruise control system to switch between different set points. Our calibrations usually have 5 set points enabled from 4500rpm in slot 1 to 5500rpm in slot 5. (Slot choice varies due to other features)Eco Shift light disable. (Optional & FOC)
Some people really dislike the Ecoboost economy shift lights and would like them disabled.
Just say the word and they are turned out forever! But the Performance shift lights remain and are improved upon! Disabling this will automatically enable the MSD peak performance shift light. (See below)Start / Stop system disable. (Optional & FOC)
Some people turn the start stop system off as the first thing they do when they get in the car.
Just say the word and we will disable it permanently for you, but leave you the option to re-enable it in your Accessport.Diagnostic and data-logging capability: (FOC)
Don't forget, the Accessport gives you the ability to diagnose management faults properly. Entering the diagnostics section of the handset will allow you to retrieve the full range of Ford fault codes. (Not just generic P-Codes like a cheap eBay reader) The icing on the cake is its high speed data-logger, allowing you to display and log over 200 engine parameters. This is the feature that unlocks the custom E-Tuning capability! Please see the Accessport tab for more detailsMSD Custom tuning, remotely! (FOC)
Using the awesome data logging capabilities of the Accessport, we invite you to send us data-logs via E-mail so that we can custom tune your purchased calibration to better suit your own, individual vehicle. After log analysis, we will send you a further optimised tune that is based of feedback from your own vehicle. This feature comes standard with all our tunes for those owners who wish to get involved in some customisation and two revisions come free of charge with every MSD Tune. But don't worry, you can enjoy the product forever without getting involved in custom tuning should you wish to.Please click here to visit our Focus RS tuning webpage for more details. (Click me).
