Accessport Installation:
What Is A Map?
The Accessport reprograms the factory tuning parameters inside the 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 heavily modified vehicles, 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.
Mounting Options
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.
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 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 may include but is not limited to Stage1, Stage2, Stage3 (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.
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 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. |

Accessport Buttons:
Standard Tuning vs SD (Speed Density) Tuning
Standard Tuning uses MAF (Mass Air Flow) sensor for air flow calculations. COBB Tuning provides Off-The-Shelf (OTS) maps created using this calculation method.
SD (Speed Density) Tuning uses MAP (Manifold Absolute Pressure) sensor for air flow calculations. Users who prefer the vehicle to be tuned by this method must either have the vehicle professionally tuned. The Accessport will not be pre-loaded with Speed Density maps.
Vehicle Identification
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 Section.
Map Selection
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 the website and reference the map notes. You can find the 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 map, average power gains, boost targets, along with other useful information.
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.
What Is A Map?
The Accessport has the capability to reprogram the factory tuning parameters inside the engine control unit (ECU) and transmission control module (TCM) using map files. Map files 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 heavily modified vehicles, 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.
Save Stock ECU/TCM Program Data
After confirming the map to be installed, the Accessport will download the current stock ECU/TCM 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.
WARNING! |
