| 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 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 requires the use of a battery charger/conditioner. 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.
2. Locate the vehicle's OBD-II port. Location of the OBD-II port may vary depending on the vehicle model.
3. Plug the OBD-II cable into the OBD-II port in the dash of vehicle.
4. Connect the small end of the OBD-II cable to the port on the bottom of the Accessport.
5. Make sure the clasp on the OBD-II cable firmly engages with the port.
6. Turn the key or ignition switch to the ‘On’ position without depressing the brake or clutch pedal.

NOTE: The engine should not be running.
7. Select [Install] from the Accessport menu by pressing the [OK] button to proceed with installation.
Accessport Buttons:
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 92307614.
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 default 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 see the map notes and their requirements for the modifications that will best fit your vehicle.
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.
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.
Save Stock ECU Program Data
After confirming the map to be installed, the Accessport will download the current stock ECU program 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! |
|---|
| If a previous installation of an Accessport is detected, you will be given the option to overwrite it 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 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. This process will take several minutes to complete.
| WARNING! |
|---|
| Do not disturb the Accessport, the OBD-II connector, or open/close any doors 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 has been 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.
