Product Introduction
Congratulations on the purchase of the Accessport hand held programmer. The Accessport is the industry leading OEM ECU flashing,
managing and monitoring assistant. Unlock power hidden within the ECU by replacing conservative factory settings with more aggressive
calibrations. The result is impressive gains in torque and horsepower while maintaining a high degree of safety. The Accessport can:
Reprogram the factory engine control unit (ECU) with improved tuning parameters through the on-board diagnostic (OBD-II) port
Monitor and log vehicle sensor data using on-screen digital gauges
Read and clear engine diagnostic trouble codes (DTCs)
Measure 0-60mph, ¼ mile times, and dyno plot
Estimate instantaneous fuel economy
Adjust idle and timing

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.

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 includes Stage1 (all octanes), Stage2
(all octanes), Anti-theft, Economy, and Valet. If you would like to view all maps available you can visit the section of ourMaps
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 Manager.
Getting Started
1. You will need the Accessport and OBD-II cable to perform the installation. Insert the key into the vehicle's ignition and leave it in the OFF
position.
2. For Subaru models utilizing an AP3-SUB-001 or AP3-SUB-002 (Not required for AP3-SUB-003) Accessport, locate the Locate the green
Test Mode connectors.

Impreza and Forester models will have this located under the driver's side dash to the left of the steering column (see left diagram). The
Legacy and Outback models will have this located on the passenger side (see right diagram). With the connectors located, enable Test Mode
by plugging the two connectors into each other. To ensure Test Mode was successfully enabled, turn the key to the ON position, but do not
start the engine. You may hear the radiator fans cycling on/off as well as the fuel pump cycling and the 'Check Engine' light should blink. THIS
IS A NORMAL FUNCTION OF TEST MODE. Once test mode is verified, turn the key back to the OFF position to continue.
NOTE: The Test Mode connectors must be connected whenever reflashing the ECU (Installing, Change Map Reflash, and
Uninstalling).
NOTE: In the event that the vehicle does not enter Test Mode after plugging in the green connectors, refer to the Troubleshooting
Section.
3. On 2002 – 2005 WRX models (AP3-SUB-001 Accessport), identify the correct Initialization Connector for your vehicle (2002 WRX = BLUE,
2003 - 2005 WRX = WHITE). Attach the Initialization Connector to the corresponding connector under the driver's side dash. This connector
will be located near the green Test Mode connectors and will be translucent white in color. Do not proceed until this step is complete.

4. Locate the vehicle's OBD-II port. Location of the OBD-II port may
vary depending on the vehicle model.
