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
Reprogram the factory transmission control module (TCM) 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
Transmission clutch gear learning*
Transmission touch point adjustment & clutch capacities*
TPMS Learning
*Available for AP3-NIS-006 and AP3-NIS-008 only.

Accessport Installation
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 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.

Screen Capture
Screenshots can be captured by holding down the [CANCEL] button for two seconds. Any stored
screen captures can be retrieved by using Accessport Manager.
Getting Started
1. Insert the key into the vehicle's ignition and leave it in the OFF position.
2. Locate the OBD-II port under the left side of the driver's side dash.
3. Connect device to the OBD-II port. Plug the OBD-II cable into the OBD-II port under the dash of
vehicle. Then connect the small end of the OBD-II cable to the port on the bottom of the
Accessport.
4. Make sure the clasp on the OBD-II cable firmly engages with the port.

5. Press the START/STOP button twice with your foot OFF the brake pedal to turn on the ignition,
but do not start the vehicle.
NOTE: The engine
should not be running.
6. Select [Install] from the Accessport menu by pressing the [OK] button to proceed with
installation.
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 or generate their own Accesstuner Race map. The Accessport will not be pre-loaded with Speed
Density maps.
