ACCESSPORT INSTALLATION
IMPORTANT! 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 o during the installation process to reduce drain on the vehicle’s
battery. For improved safety during installation, a car battery charger must be
connected to the vehicle during the installation process.
Getting Started:
1. You will need the Accessport and OBD-II cable to perform the installation.
Make sure the key fob is present inside the cabin.
2. Locate the vehicle’s female OBD-II port under the driver’s side dash.

6. Next, without touching the brake pedal press the START button twice. It
is required that you turn o climate control by pushing the fan control dial
on your HVAC controls. You will also need to turn o the headlights and
shut all doors. NOTE: The engine should not be running.
4. Connect the small end of the OBD-II cable to the 10 pin port on the
bottom of the Accessport. NOTE: Your Accessport may only have 9 pins.
This is by design.
5. Make sure the clasp on the OBD-II cable rmly engages the tab on the
10 pin port.
3. Plug the OBD-II cable into the OBD-II port under the dash of vehicle.

7. Select Install to proceed with installation.
Vehicle Identication:
The Accessport will attempt to automatically determine the target vehicle
for installation.
If the Accessport successfully identies the vehicle:
Verify that the identied vehicle is correct and press OK to conrm. The
Accessport is equipped with a Boost Wrap feature that will allow the factory
Multi-Function Display(MFD) to display more than 20psi/150kPa of boost. In
order for this feature to work more accurately you need to select what units
you have your MFD boost gauge set to. Select the units you wish to use and
press OK to conrm. Note: You can go back later and change the units in the
settings menu.
If an error occurs:
Please reference the Troubleshooting section of the Accessport User Manual
for additional information. The Accessport User Manual can be found online
at www.cobbtuning.com/nissan-ap
ECU Map selection:
After the Accessport identies the vehicle, it will present a list of maps for
that vehicle. The map selected will become the base map for the vehicle.
To ensure the best performance, select the map that most closely matches
the modication level of the vehicle. Select a map and press OK to view
detailed information about that map. After conrming that the selected
map is correct, press OK again to proceed, or press CANCEL to return to the
map selection list.
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.The stock data is used during the uninstall process to return 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.
WARNING!
Do not disturb the Accessport or OBD-II cable while installation is taking
place. Failure to do so may result in incomplete ECU reprogramming
which will render the vehicle inoperable.

Save Stock TCM Program Data (If applicable):
The Accessport has the ability to save the stock TCM 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. The stock data is used during the uninstall process
to return 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 ECU Programming:
With the stock ECU data saved, the Accessport will 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 selected map
le. This process will take several minutes to complete.
Install Accessport TCM Programming (If applicable):
With the stock TCM data saved, the Accessport will proceed with
installation to the vehicles TCM. At this point the Accessport
reprograms the vehicle’s TCM with new program data and calibration
parameters from the selected map le. This process will take several
minutes to complete.

The last installation process the Accessport goes though is clearing
trouble codes. When this step is complete turn o the ignition and wait for
approximately 10 seconds. After that is done your screen should now display
“Installation Complete”.You may now unplug the Accessport from the vehicle.
The Accessport does not need to be plugged in to the vehicle again until a
map change is necessary, however, it can remain plugged in to use the
Performance testing, Live Data monitoring and Data Logging features. 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.

MAP & FIRMWARE MANAGEMENT
What Is A Map?
The Accessport reprograms the tuning parameters inside the factory
engine control unit (ECU) using map les, which contain specially written
instructions for the Accessport to follow during the reprogramming
process. A given map le contains programming information to properly
calibrate the ECU for a specic set of modications to a vehicle. In addition
to calibrating for specic modications, maps are also programmed for
dierent uses, such as improved performance, higher fuel eciency,
alternate fuel grades, anti-abuse (valet) and anti theft. Through the use of
the Accessport and dierent map les, the ECU can be reprogrammed to
accommodate the user’s immediate need.
Downloading and Installing the Accessport Manager Software:
The Accessport Manager Software can be found at www.cobbtuning.
com/apmanager. Please follow all on-screen instructions during the
installation process.
Acquiring And Loading New Accessport Maps:
The Accessport ships with a number of pre-installed maps that are up-to-
date at the time of shipping. However, it is possible that newer revisions
of maps have been made available, or that the Accessport did not come
pre-installed with a map that is appropriate for the target vehicle. To load a
new or updated map to the Accessport, simply download and the map le
to an easy to remember location (My Documents, Desktop, etc.). Then, drag
and drop the map le in to AP Manager to transfer it to your Accessport.
Continue this process for all desired maps.
How do I update the software on my Accessport?
Designed with user friendliness in mind, Accessport Manager will
automatically communicate with COBB’s servers to nd and download
the latest Accessport application and rmware packages. Simply plug
in the Accessport, using the provided USB cable, and launch Accessport
Manager. All rmware details are handled for you. Just sit back and wait
for completion.
