Accessport Installation
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.
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 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: Map transferring is not compatible with CARB approved Accessports.
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 Ford Tab in the Maps section
of our website.
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

Page | 7
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
lights, and any other electronic device that uses the car battery for power.
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. 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. For keyless cars, make sure the vehicle is in
the OFF state.
2. Locate the vehicle's OBD-II port. Location of the OBD-II port may vary depending on the vehicle
model. The Focus ST has a covered OBD-II port shown below in “Image1”. The Fiesta ST is
located just under the plastic trim behind the hood latch release (see Image2).

permanently lost and unrecoverable. In the case of a previous install, a stock ECU program
supplied on the Accessport will be used when you uninstall.
Install Accessport Programming
The Accessport will automatically proceed with installation to the vehicle. At this point the Accessport
reprograms the vehicle's ECU with new program data and calibration parameters from the installation
map file.

Page | 11
WARNING!
Do not disturb the Accessport and the OBD-II connector while installation is taking place.
Failure to do so may result in incomplete ECU reprogramming which will render the vehicle
inoperable. If an error occurs during the reflash, the Accessport will enter Recovery Mode
and attempt to recover the reflash.
Installation Complete
Follow all on-screen prompts on the Accessport to complete the installation process. The Accessport is
now fully installed and ready for use and the vehicle's ECU is programmed with new calibration data.
The Accessport does not need to be plugged into the vehicle for the calibration to be in effect. You can
disconnect the Accessport at this time or leave it plugged in to use any of the many features outlined
below.
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.

Accessport Features & Functionality
Gauges
The Accessport can read sensor data from the factory ECU and display it as an on-screen gauge. This
feature allows the Accessport to function as an auxiliary gauge displaying boost, RPM, temperature, or
any number of other parameters available in the factory ECU.
The Accessport can also record sensor data from the factory ECU while you drive. With the ability to
store multiple sessions, the Accessport can function as a complete engine datalogger and diagnostic
tool. To begin datalogging, press the [OK] button while in the Gauges function. While the Accessport is
recording a datalog, a single light blue light will scroll in the shift light. To view the results of your
datalog sessions, simply connect the Accessport to your PC and retrieve the results using the AP
Manager software. Data Log recordings are stored in a .csv (Comma Separated Values) format and are
easily viewed using any spreadsheet application.
When you first select the Gauges function you will be defaulted to the Change Gauge Layout list so you
can select which layout you prefer.
