Congratulationson the purchase of the Accessport hand held programmer. The Accessport is the industry leading OEM ECU flashing, managing and monitoring assistant. Unlock power hidden within the ECU by replacing conservative factory settings with more aggressive calibrations. The result is impressive gains in torque and horsepower while maintaining a high degree of safety. The Accessport can:

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.

For installation purposes, it is important to ensure that the vehicle's battery has adequate power for both the Accessport and the ECU. Because of this, it is recommended that all in-car electronics and vehicle lights are turned off during the installation process to reduce drain on the vehicle's battery. For improved safety during installation, a car battery charger can be connected to the vehicle during the installation process.

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.

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.

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.

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.

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.

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.

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.

To enter the Setup function, press the [Up] button to select the header. Now press the [Up] key to highlight the arrow button next to Setup and press [OK] to view the sub-menu.

Press [OK] and using the [Up] and [Down] buttons, set the RPM to the desired level to have the shift light flash. Press [OK] to save the RPM you have selected. By default, the shift light RPM is set above the stock redline. This essentially disables the shift light since that RPM will not be reached. You will need to lower the shift light RPM to enable this feature.

This list allows the user to enable and disable items for logging. Only monitors with a green circle will be recorded while using the datalogging feature. A default log list including a group of monitors complied by our in-house tuners has been provided. You can make changes to the log list by highlighting a monitor and pressing the [OK] button to activate/deactivate it for logging. Pressing the [Cancel] button will save any changes you have made to the datalog list.

NOTE: The Accessport is only capable of communicating with the ECU while the ignition is turned to the "ON" position. The Accessport will display an error message if it cannot communicate with the vehicle.

Use this function to read trouble codes from the engine computer. Stored codes indicate a mechanical or electrical fault. Use the up/down buttons to highlight a code and display a short description of the trouble code (if available).

Use this feature to read emissions readiness test statuses of your vehicle. To read emissions readiness, Select Troubleshooting from the main menu. Then, scroll to I/M Readiness. You will see an extensive list of readiness monitors.

To change the mapping on your ECU, select this menu option and follow the instructions. The ignition must be turned to the "ON" position with the engine off during the Change Map operation. You will be prompted to select a pre-loaded map. The same warnings that apply to the installation process apply here as well (battery charge level, turn accessories off, etc.)

Selecting this option will remove the Accessport programming from the vehicle on which it is installed, reverting the ECU to a stock state. It is highly recommended to uninstall the Accessport prior to taking your car to the dealer for any type of service. It is also crucial that you uninstall your Accessport if you plan on selling your vehicle or Accessport separately. Otherwise the Accessport will still be paired to your vehicle and cannot be installed on another car.

Context Help: Shows more information about the screen you are currently viewing. Button Help: Displays the button map. Icon Help: Displays the various icons you will find on the Accessport. Demo Mode: This function allows you to run through a mock installation and use all of the features of the Accessport without connecting to a vehicle.

If an error occurs during a reflash the Accessport and ECU will enter recovery mode. By selecting this option the Accessport will uninstall itself, leaving your ECU in a stock state so that you can start over.

NOTE: For Recovery Mode to function correctly, you must first resolve the condition that caused the initial reflash failure. For example, if your battery voltage dropped too low during the reflash, put a battery charger on the car before attempting to use Recovery Mode.

The Accessport is designed to be operated at temperatures between 32 and 95 F (0 and 35 C) and with a relative humidity below 90%. Using the Accessport outside of these recommendations may result in damage.

The Accessport is thermally protected and will not function if the temperature reaches extremely hot levels. If the Accessport is not booting up correctly or the screen does not show everything correctly, turn the device off and move it to a cooler environment temporarily.

Never attempt to open your Accessport or any associated equipment. Doing so puts the components at risk of damage from, but not limited to, static shock. No user-serviceable parts are inside. At no time will ANY authorized representative of COBB Tuning, Inc. ask you to open or mechanically/electronically alter the Accessport.
