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.

Page 7

IMPORTANT!

Before installing the Accessport on the vehicle, it is important to verify that the vehicle is

electronic device that uses the car battery for power.

Accessport Installation

Pre-Installation

The Accessport comes with the most up-to-date software 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 software and map files for the target vehicle.

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

program supplied on the Accessport will be used when you uninstall.

Vehicle Identification

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 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 reprograms the ECU with the calibration data from the map file selected for installation. It is important to select the map file that most closely matches the modif ication level of the target vehicle.

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 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

Once the vehicle is in ECU reprogramming mode, the Accessport will first download the current stock ECU program data from the vehicle. The Accessport saves this data for use when uninstalling to ensure that the vehicle is returned to the exact state it was in before the Accessport was installed. The download process will take 8-9 minutes to complete.

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

Install Accessport Programming

After the Accessport downloads and saves the stock ECU program data, it will proceed with installation to the vehicle. It is at this point that the Accessport reprograms the vehicle's ECU with the new program

WARNING!

Do not disturb the Accessport and the OBD-II cable while installation is taking place. Failure to do so may result in incomplete ECU reprogramming which will render the vehicle inoperable.

WARNING!

Installing an Accessport may void powertrain and associated warranties. COBB Tuning makes

data and calibration parameters from the selected map file. This process will take 10 minutes to complete.

Installation Complete

The Accessport is now fully installed and ready for use. Turn the key to the OFF position and unplug the OBD-II cable from the vehicle.

The vehicle's ECU is now programmed with new calibration data. The Accessport does not need to be plugged 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 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.

Dealer Service/Visit

Prior to any visit to your dealer for service, COBB Tuning recommends uninstallation of the Accessport from your vehicle. This will help minimize warranty complications with your modified vehicle.

Note: Occasionally, dealers will update the ROM revision on your vehicle's ECU. If this happens, there is a chance that the new ROM revision is unrecognized by the Accessport, evidenced by the fact that the Accessport will no longer successfully identify the vehicle during installation. If this happens, please follow ROM-dump instructions here. Please note that it may take up to 5 work days for the new ROM revision to be supported.

no claim of liability for loss of warranty stemming from the use of the COBB Tuning Accessport or associated parts. Installation of the COBB Tuning Accessport releases COBB Tuning from all
