Congratulations on the purchase of the Accessport handheld 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:

• Reprogram the factory engine control unit (ECU) with improved tuning parameters through the on-board diagnostic (OBD-II) port

• Monitor and log vehicle sensor data using on-screen digital gauges

• Read and clear engine diagnostic trouble codes (DTCs)

• Measure 0-60mph, and ¼ mile times

• Adjust idle and timing
  
  
  

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.

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. 

Screenshots can be captured by holding down the [CANCEL] button for two seconds. Any stored screen captures can be retrieved by using Accessport Manager.

To change the Accessport's startup screen see the tutorial here.

1. You will need the Accessport and OBD-II cable to perform the installation. Insert the key into the vehicle's ignition and leave it in the OFF position. 

Open

2. For Subaru models utilizing an AP3-SUB-001 or AP3-SUB-002 (Not required for AP3-SUB-003) Accessport, locate the green Test Mode connectors.

Open

Impreza and Forester models will have this located under the driver's side dash to the left of the steering column (see left diagram). The Legacy and Outback models will have this located on the passenger side (see right diagram). With the connectors located, enable Test Mode by plugging the two connectors into each other. To ensure Test Mode was successfully enabled, turn the key to the ON position, but do not start the engine. You may hear the radiator fans cycling on/off as well as the fuel pump cycling and the 'Check Engine' light should blink. THIS IS A NORMAL FUNCTION OF TEST MODE. Once test mode is verified, turn the key back to the OFF position to continue. 

• NOTE: The Test Mode connectors must be connected whenever reflashing the ECU (Installing, Change Map Reflash, and Uninstalling).

• NOTE: In the event that the vehicle does not enter Test Mode after plugging in the green connectors, refer to the Troubleshooting Section.
  
  
  

3. On 2002 – 2005 WRX models (AP3-SUB-001 Accessport), identify the correct Initialization Connector for your vehicle (2002 WRX = BLUE, 2003 - 2005 WRX = WHITE). Attach the Initialization Connector to the corresponding connector under the driver's side dash. This connector will be located near the green Test Mode connectors and will be translucent white in color. Do not proceed until this step is complete.

4. Locate the vehicle's OBD-II port. The location of the OBD-II port may vary depending on the vehicle model.

Open

5. Plug the OBD-II cable into the OBD-II port under the dash of vehicle. Then connect the small end of the OBD-II cable to the port on the bottom of the Accessport.

Open

6. Make sure the clasp on the OBD-II cable firmly engages with the port.

Open

7. Insert key into vehicle ignition and turn it to the ON position. Make sure climate control, headlights, and the radio are all turned off. If equipped with a push-button start, hit the start button twice without depressing the brake or clutch pedal.

NOTE: The engine
should not be running.

8. Select [Install] from the Accessport menu by pressing the [OK] button to proceed with the installation.

Accessport Buttons: 

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.

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.

After confirming the map to be installed, the Accessport will download the current stock ECU program data from the vehicle. The Accessport saves this data for use during the uninstall process to ensure that the vehicle is completely returned to stock. The download process will take a few minutes to complete. 

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. If applicable, disconnect the Test Mode connectors (green) you connected in Step 2 and the Initialization Connector you connected in Step 3. These connectors MUST be disconnected before operating the vehicle. 

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. 

NOTE: AP3-SUB-002 and AP3-SUB-003 cars will need to recalibrate the drive-by-wire throttle body system after a reflash or ECU reset. After a reflash, when you first turn the key to the ON position the throttle blade will open fully then return to a closed position. During these few seconds, the engine may not start. This is perfectly normal behavior. The engine will start when this process is done.

The best way to proceed after a reflash or ECU reset is to turn the key to the ON position and count to 5 – 10 seconds before trying to start the engine. If you follow this simple procedure, the engine will fire up on the first try.

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

Note: While in the Change Monitor list, you can press [UP] to find a Sort Monitors option. This option will sort all monitors in reverse alphabetical order. 

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

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.

Change Gauge Layout – Select a gauge layout from a single large gauge to many small gauges

Imperial – This unit scheme uses imperial units: F, mph, PSI, AFR

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. 

Press [UP] to find the Setup option for the Shift Light, where you will find the following options: 

Disable Shift Light – Disables the shift light function and removes the shift light from the gauges screen. 

• NOTE: When you initiate a datalog, the shift light will reappear to notify you that you are logging. 

Reset Shift Light – Resets the shift light back to the default value.

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 compiled 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.

Press [UP] to find the Setup option for Configure Datalog where you will find the following options: 

Clear Monitors – Clear all monitors from the datalog list

Load a Datalog Preset - Load a predefined set of datalog monitors

• See Data Log Presets for complete details

Reset to Defaults – Restore the datalog list to the default list 

Save a Datalog Preset - Save the current list of datalog monitors to quickly load later

• See Data Log Presets for complete details

Sort Monitors – Sort the monitor list alphabetically, then reverse-alphabetically 

The Accessport can calculate several performance measurements. 

To record the 0-60 MPH performance, select this menu option and follow instructions. A time slip showing the performance results will be displayed at the end of the performance test.

To record the ¼ Mile performance, select this menu option and follow instructions. A time slip showing the performance results will be displayed at the end of the performance test.

Press [UP] to find the Setup option for Performance where you will find the option to Change Units.

Imperial – This unit scheme uses imperial units: F, mph, PSI, AFR

Use the Accessport as a diagnostic tool.

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 function to reset all trouble codes. 

NOTE: Just like pulling the negative battery terminal to reset the ECU, this will clear out any stored compensations and optimizations made by the ECU (such as long term fuel trims). If you are running a different realtime map than your reflash map, it will also reset your realtime map. 

NOTE: AP3-SUB-002 and AP3-SUB-003 cars will need to recalibrate the drive-by-wire throttle body system after a reflash or ECU reset. After a reflash, when you first turn the key to the ON position the throttle blade will open fully then return to a closed position. During these few seconds, the engine may not start. This is perfectly normal behavior. The engine will start when this process is done.
