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 Troublshooting 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 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
our website. You can find 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 of our maps.
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 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.
