Mounting Options

A universal 'sticky' mount is included with the Accessport. For the best results, we recommend installing the mount vertically, and preparing the mounting surface with the included alcohol wipe. 

• NOTE: It's important to note that not all surfaces provide a strong adhesive bond. 

• NOTE: The Accessport cradle is compatible with "Dual T" style mounts.

Pre-Installation

The Accessport comes with the most up-to-date software and map files available at the time of shipment. However, it is possible that updated software and/or map files have been made available since the time of shipment. Therefore, the recommended procedure is to connect the Accessport to the AP Manager software and download the latest firmware for the target vehicle. Please visit www.cobbtuning.com/apmanager to download AP Manager and to find a link for the AP Manager manual. 

If you have issues transferring maps or updating the Accessport while using USB 3.0 ports, please try using a USB 2.0 hub adapter. 

• NOTE: The Accessport is preloaded with a default set of maps for all cars that it supports. This includes Stage1 (all octanes), Stage2 (all octanes), Anti-theft, Economy, and Valet. If you would like to view all maps available you can visit the Maps section of our website.

Accessport Buttons: 

Vehicle Identification

The Accessport will attempt to automatically determine the target vehicle for installation. Verify that the identified vehicle is correct and press [OK] to confirm.

If an error occurs:
Please refer to the Troubleshooting.

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 visit the Maps section of our website. You can find map notes for each of our maps by clicking on your vehicle and choosing your intake type. The map notes will list the modification requirements for each of our maps. 

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. After reading the description, you can press [CANCEL] to go back to the map list or press [OK] to select that map and proceed with the installation. 

What Is A Map?

The Accessport reprograms the tuning parameters inside the factory 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 for a heavily modified vehicle to an economy map for a stock vehicle. Through the use of the Accessport and different map files, the ECU can be reprogrammed to accommodate virtually any vehicle configuration.

Save Stock ECU Program Data

The Accessport has the ability to save the stock ECU program data.  However, it takes approximately 30 minutes to complete.  Pressing [CANCEL] will skip the process of saving the stock data; pressing [OK] will proceed with saving the stock data.  A battery charger will be needed to complete the save.  The stock data is used during the uninstall process to return your ECU to stock.  If the stock data is not saved, stock data supplied with the Accessport will be used when the Accessport is uninstalled.  There is no disadvantage to skipping this step and using the stock data supplied with the Accessport.

Install Accessport Programming

With the stock ECU data saved, 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. This process will take several minutes to complete.

Installation Complete

Follow all on-screen prompts on the Accessport to complete the installation process. The Accessport is now fully installed and ready for use and the vehicle's ECU 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.

Please note that the Accessport is designed to work with only one vehicle at a time. Once the Accessport is installed, it cannot be used with another vehicle until it is uninstalled from the original vehicle.

Accessport Features & Functionality

Gauges

The Accessport can read sensor data from the factory ECU and display it as an on-screen gauge. This feature allows the Accessport to function as an auxiliary gauge displaying boost, RPM, temperature, or any number of other parameters available in the factory ECU. 

The Accessport can also record sensor data from the factory ECU while you drive.  With the ability to store multiple sessions, the Accessport can function as a complete engine datalogger and diagnostic tool.  To begin datalogging, press the [OK] button while in the Gauges function.  While the Accessport is recording a datalog, a single blue light will appear and oscillate through the shift light. To stop datalogging, press the [OK] button again. To view the results of your datalog sessions, simply connect the Accessport to your PC and retrieve the results using the AP Manager software.  Data Log recordings are stored in a .csv (Comma Separated Values) format and are easily viewed using any spreadsheet application. 

When you first select the Gauges function you will be defaulted to the Change Gauge Layout list so you can select which layout you prefer. 

Press the [Up] or [Down] button to select the header. Then press the [Down] button to highlight the monitor you would like to interact with and press [OK]. You will then be presented with the following options.

Change Monitor – Select the monitor that will be shown in the selected gauge

Reset Current Min/Max – Reset the minimum and maximum values of the selected gauge 

Reset All Min/Max – Reset the minimum and maximum values of all gauges

Setup
