The Accessport will attempt to automatically determine the target vehicle for installation. Verify that the identified vehicle is correct and press OK to confirm.  You will then proceed to selecting the “map” or tune you wish to install.

What Is A Map?

The Accessport reprograms the factory tuning parameters inside the engine control unit (ECU) using map files, which contain specially written instructions for the Accessport to follow during the reprogramming process. A map file can contain information for any number of different modifications or enhancements to a vehicle, ranging from a race map to an economy map for vehicles in different configurations. Through the use of the Accessport and different map files the ECU can be reprogrammed to accommodate virtually any vehicle configuration.

Map Selection

After the Accessport identifies the vehicle, it will present a list of maps. Maps that are not intended for the identified vehicle are displayed in gray. The Accessport will reprogram the ECU with the calibration data from the map selected for installation. This will become the base data for the ECU. To ensure the best performance, select the map that most closely matches the modification level of the vehicle.

If you are unsure about which map applies to your modification level, please see the Mustang EcoBoost Map notes for the for the modification requirements for each map.

Select a map and press OK to proceed with the installation. If you wish to see a longer description for the highlighted map, press and hold the OK button on the desired map.

The Accessport will automatically proceed with installation to the vehicle.  At this point the Accessport reprograms the vehicle’s ECU with new program data and calibration parameters from the installation map file.

Follow all on-screen prompts on the Accessport to complete the installation process. The Accessport is now fully installed and ready for use on your Mustang and it is programmed with new calibration data. The Accessport does not need to be plugged into the vehicle for the calibration to be in effect. You can disconnect the Accessport at this time or leave it plugged in to use any of the many features outlined below.

Modification Requirements and Power Gains

Accessport Features for Mustang EcoBoost

COBB Flat Foot Shift (MT Only): Improve shift times and keep boost built during shifts. Flat Foot Shifting can hold engine RPM at a set RPM between 3000-8000 RPM during shifting. This feature is enabled in COBB OTS maps.

COBB Transbrake and Bump Box (AT Only): A Transbrake is a drag racing feature for an automatic car that holds the car in one spot while getting ready to launch and doesn’t use the brakes.  The bump box allows you to creep up or bump up into the staging lights.

COBB Launch Control: Adjust Launch Control on the fly with 6 pre-configured RPM slots to dial in launch based on track conditions and vehicle configuration. Enabled in OTS Maps and configurable within Accesstuner Pro.

COBB Change Map Slot: Map switching allows for instant changes to several tables inside the vehicles calibration without having to re-flash the ECU! Each “Map Slot” is grouped into a folder found inside the Map Switching Features group. When a map slot is selected by the driver, the ECU will use the corresponding values as defined in each folder. Further Documentation can be found here.

COBB Burnout Mode: Enabled in OTS (Off the Shelf Maps) This feature allows you to hold the car at a predetermined RPM and perform a burnout. Burnout mode prevents you from over revving the engine while performing a burnout!

COBB Adjustable Traction Control: Adjust target traction slip on the fly (Slots 1-8) and maximize tire grip to best suit given track conditions (wet/damp/dry/street/slip/burnout/etc). Note: Feature must be enabled in ECU calibration for use.

I Tuned my Mustang, Now What?

The Accessport for the EcoBoost Mustang is a powerful tool. Aside from being able to flash the ECU with different tunes, and a diagnostic tool able to read and clear codes, it can also display and record hundreds of different parameters. From Ambient Air Temperature to Vehicle Speed Sensors and everything in between, the Accessport will be able to provide you with the data you need.

Data Monitoring

The Gauges menu contains all monitoring and datalogging settings. The first time a V3 Accessport enters the Gauges menu, you’ll be asked how many monitors you would like to display.

Each time you return to the Gauges menu, the selected layout/number of gauges will be used until it is changed in the Gauges Setup menu. This provides the ability to monitor different things in different situations. You can select 1 or 2 gauges to be prominently displayed for the track and have different settings with more gauges for street/economy monitoring.

Every Mustang Accessport will come with the same default monitor log list. This is a good starting point to get an overview of what the car is doing. If you wanted to determine something more specific, you can change the monitors that are being datalogged.  This can be done by

Entering the Gauges menu

Then, enter the datalogging/gauges setup menu by selecting the arrow at the top of the gauges screen, then enter the Configure Datalogging menu.

Once in the Configure Datalogging menu select the monitors you would like to log.

Then, press the Back (left) button to save the changes. You’re ready to take a log!

Datalogging

It’s important that certain conditions are present when trying to determine if the car is healthy and performing as it should. Typically, you won’t get much relevant diagnostic data through idling or light throttle conditions. We recommend a 3rd gear Wide Open Throttle pull from about 2500 RPM to near redline. Any potential issues will usually be evident during this event.

To begin the log enter the Gauges menu

Then, press the OK (center) button to start datalogging. Once started, a scrolling dot will appear on the screen along with the logging rate displayed at the bottom.

Press the OK button or Cancel button to stop datalogging. You can then connect the Accessport to Accessport Manager on your computer and download the catalog files in the Manage tab. Up to ten (10) datalogs can be stored on the Accessport at any time. The lowest number is the oldest log and the highest number is the newest.

You can then open the datalog in any spreadsheet or log viewer application. For most applications, double-clicking on the datalog will open the file properly.
