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.
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 software and map files for the target vehicle. Please see AP Manager Software Manual for more information.
AccessPORT Installation
1. Insert the key into the vehicle’s ignition and leave it in the OFF position.
2. 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.
