AP Software CD
Getting Started :
1. Insert the key into the vehicle’s ignition and leave it in the OFF position.
2. Locate the vehicle’s female OBD-II port under the right side of the driver’s side dash.
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
3. Connect the small end of the provided USB cable to the mini-USB port on the back of
the OBD dongle.
4. Plug the OBD dongle into the OBD-II port under the dash of vehicle.
5. Plug the large end of the USB cable into the standard USB port on the underside of
your AccessPORT. At this point the AccessPORT will power up and present the
to proceed with installation.
The AccessPORT will attempt to automatically determine the target vehicle for installation.
If the AccessPORT successfully identifies the vehicle:
Verify that the identified vehicle is correct and press OK to confirm.
If an error occurs:
Please reference the Troubleshooting section of the AccessPORT User’s Guide located
on the provided AccessPORT CD for additional information.
Map Selection :
After the AccessPORT identifies 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
modification level of the vehicle. Select a map and press OK to view detailed
information about that map. After confirming 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:
After confirming the installation map, the AccessPORT will download the current
stock ECU program data from the vehicle. This 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 3 - 4 minutes to complete.
Install AccessPORT 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 file. This process will take several
minutes to complete.
Your screen should now display “
Installation Complete. Turn key to off position.”
The AccessPORT is now successfully installed. Turn the key to the OFF position, unplug
the OBD connector and wait for approximately 10 seconds. The AccessPORT does not
need to be plugged into the vehicle again until a map change is necessary. 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
Do not disturb the AccessPORT, the USB cable, or the OBD connector while installation
is taking place. Failure to do so may result in incomplete ECU reprogramming which
will render the vehicle inoperable.
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.
Installing the AccessPORT AP Manager Software:
Insert the AP Manager Software CD into your computer’s CD or DVD reader. The software
will automatically install itself on to your computer. 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 check for newer or diferent maps, please direct your web browser to the AccessPORT
map download page at http://www.cobbforums.com/maps. The most up-to-date maps
are always made available on this page.
To load a new map to the AccessPORT, simply download the desired map from the
AccessPORT map download page. Save the map file to an easy-to-remember location
(My Documents, Desktop, etc.). After the map file is completely downloaded, double-
click the map file to automatically run the AP Manager software and import it to the
map library. With the map file in the AP Manager library, simply right-click on the map
and select “Send to AccessPORT.” Continue this process for all desired maps.
The AccessPORT is now completely up-to-date!
