WARNING!
Installation and use of the AccessPORT may void all or a portion of
the vehicle manufacturer's standard warranty. There is no guarantee
expressed or implied by COBB Tuning or any of its affiliates for the
use of the AccessPORT. The user accepts all risks and
responsibilities when using the AccessPORT.
WARNING!
Use of the AccessPORT while operating a moving vehicle is strictly
prohibited by law. COBB Tuning and its affiliates accept no
responsibility for damages or injury caused by misuse of the
AccessPORT.
WARNING!
The AccessPORT may not be able to function if the vehicle's wiring
has been modified. If problems occur while using the AccessPORT,
please verify that all wiring to and from the ECU is correct and
functional.

What Is A Map?
The AccessPORT repro rams the tunin parameters inside the factory en ine control unit
(ECU) usin map files, which contain specially written instructions for the AccessPORT to
follow durin the repro rammin process. A map file can contain information for any number
of different modifications or enhancements to a vehicle, ran in from a race map for a
heavily modified vehicle to an economy map for a stock vehicle. Throu h the use of the
AccessPORT and different map files the ECU can be repro rammed to accommodate
virtually any vehicle confi uration.
Revision 1.094 Mar 8, 2012

AccessPORT Installation Pa e 8
AccessPORT Installation
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 AccessPORT Updater and AP Mana er software and
download the latest software and map files for the tar et vehicle. Please install the Software
CD for more information.
IMPORTANT!
Before installing the AccessPORT on the vehicle, it is important to verify that the
vehicle is adequately prepared for the installation process. Since the
AccessPORT uses the vehicle's battery for power and the ECU reprogramming
process requires adequate battery power as well, it is critical to verify that the
vehicle's battery has a good charge. This can be done through the use of a
battery charger/conditioner or by driving the vehicle for a period of time prior to
installation to allow the alternator to recharge the battery. Furthermore, please
ensure that all in-car electronic devices are turned off to reduce power draw on
the battery. This includes car stereos, video screens, GPS units, radar detectors,
interior and exterior vehicle lights, and any other electronic device that uses the
car battery for power.

AccessPORT Installation Pa e 9
Getting Started
1. Insert the key into the vehicle's i nition and leave it in the OFF position.
2. Locate the vehicle's OBD-II port under the left side of the driver's side dash.
3. Connect device to the OBD-II port.
a) (AccessPORT Version 2 only):
•Connect the small end of the provided USB
cable to the mini-USB port on the back of the
OBD connector.
•Plu the lar e 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 after a few moments
present the installation menu.
•(EVO III and EVO IX only) Plu the
white sub-connector of the OBD
don le into the white connector
immediately to the left of the OBD-II
port under the dash. The white
connector must to be connected for
all operations.

b) (AccessPORT Version 2b only):
•Plu the OBD-II cable into the OBD-II port
under the dash.
•Connect the other end of the OBD-II cable
to the 10-pin port on the bottom of the
AccessPORT. At this point the
AccessPORT will power up and after a few
moments present the installation menu.
4. Plu the lar e 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
installation menu after approximately 20-30 seconds.
5. Select [Install] from the AccessPORT menu by pressin the [OK] button to proceed
with installation. The i nition key must be in the ON position. Below is a dia ram of
the AccessPORT's keypad function.
Revision 1.094 Mar 8, 2012

Vehicle Identification
The AccessPORT will attempt to automatically determine the tar et 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 refer to [TROUBLESHOOTING SECTION].
Map Selection
Once the AccessPORT determines the installation vehicle type, it will present a list of maps
from which to choose for installation. The AccessPORT repro rams the ECU with the
calibration data from the map file selected for installation. This is the calibration data that the
ECU will use by default if it is reset due to power loss. For this reason, it is important to
select the map file that most closely matches the modification level of the tar et vehicle at
the time of install.
If you are unsure about which map applies to your modification level, please see the map
notes and their requirements for the modifications that will best fit your vehicle.
Select a map and press [OK] to view detailed information about that map. After confirmin
that the selected map is correct, press [OK] a ain 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 pro ram data. However, it takes
approximately 15 minutes to complete. Pressin CANCEL will skip the process of savin the
stock data; pressin OK will proceed with savin the stock data. The stock data is used
durin 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 disadvanta e to skippin this step and usin the stock data supplied with the
AccessPORT.
WARNING!
If a previous installation of an AccessPORT is detected, you will be given the
option to overwrite it with a new installation. Be aware that the previous
installation will be permanently lost and unrecoverable. This detection may occur
prior to saving the stock ECU program data, in which case the ECU program data
will not be saved. In the case of a previous install, a stock ECU program supplied
on the AccessPORT will be used when you uninstall.
Revision 1.094 Mar 8, 2012

AccessPORT Installation Pa e 12
Install AccessPORT Programming
After the AccessPORT downloads and saves the stock ECU pro ram data, it will proceed
with installation to the vehicle. It is at this point that the AccessPORT repro rams the
vehicle's ECU with the new pro ram data and calibration parameters from the selected map
file. This process will take 3-4 minutes to complete.
WARNING!
Do not disturb the AccessPORT, and the USB cable and the OBD connector
(Version ) or the OBD-II cable (Version b) while installation is taking place.
Failure to do so may result in incomplete ECU reprogramming which will render
the vehicle inoperable.
Installation Complete
The AccessPORT is now fully installed and ready for use. Turn the key to the OFF position
and unplu the OBD connector from the vehicle.
The vehicle's ECU is now pro rammed with new calibration data. The AccessPORT does
not need to be plu ed into the vehicle for the calibration to be in effect, however, there are
other features of the device that may be used at any time.
Please note that the AccessPORT is desi ned 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.
WARNING!
The AccessPORT is not designed to be used by a driver while the
vehicle is in motion. All AccessPORT functions should be performed
by a passenger while the vehicle is in motion. Under no
circumstances should the driver exceed posted speed limits or
disobey traffic laws while using the AccessPORT. COBB Tuning and
its affiliates assume no responsibility for damages caused by
improper use of the AccessPORT.
