The engine will start when this process is done. During these few seconds, the engine may not start. After a reflash, when you first turn the key to the ON position the throttle blade will open fully then return to a closed position.
NOTE: AP3-SUB-002 and AP3-SUB-003 cars will need to recalibrate the drive-by-wire throttle body system after a reflash or ECU reset. Once the Accessport is installed, it cannot be used with another vehicle until it is uninstalled from the original vehicle. Please note that the Accessport is designed to work with only one vehicle at a time. You can disconnect the Accessport at this time or leave it plugged in to use any of the many features outlined below. The Accessport does not need to be plugged into the vehicle for the calibration to be in effect. The Accessport is now fully installed and ready for use and the vehicle's ECU is programmed with new calibration data. These connectors MUST be disconnected before operating the vehicle.
If applicable, disconnect the Test Mode connectors (green) you connected in Step 2 and the Initialization Connector you connected in Step 3. After reading the description, you can press to go back to the map list or press to select that map and proceed with the installation.įollow all on-screen prompts on the Accessport to complete the installation process. If you wish to see a longer description for the highlighted map, press and hold the button on the desired map. Select a map and press to proceed with the installation. The map notes will list the modification requirements for each of our maps. You can find map notes for each of our maps by clicking on your vehicle and choosing your intake type. If you are unsure about which map applies to your modification level, please visit the Maps section of our website. To ensure the best performance, select the map that most closely matches the modification level of the vehicle. This will become the base data for the ECU. The Accessport will reprogram the ECU with the calibration data from the map selected for installation. Maps that are not intended for the identified vehicle are displayed in gray. NOTE: In the event that the vehicle does not enter Test Mode after plugging in the green connectors, refer to the Troubleshooting Section.Īfter the Accessport identifies the vehicle, it will present a list of maps.NOTE: The Test Mode connectors must be connected whenever reflashing the ECU (Installing, Change Map Reflash, and Uninstalling).Once test mode is verified, turn the key back to the OFF position to continue. You may hear the radiator fans cycling on/off as well as the fuel pump cycling and the 'Check Engine' light should blink. To ensure Test Mode was successfully enabled, turn the key to the ON position, but do not start the engine. With the connectors located, enable Test Mode by plugging the two connectors into each other. The Legacy and Outback models will have this located on the passenger side (see right diagram). Impreza and Forester models will have this located under the driver's side dash to the left of the steering column (see left diagram). For Subaru models utilizing an AP3-SUB-001 or AP3-SUB-002 ( Not required for AP3-SUB-003 ) Accessport, locate the green Test Mode connectors. (Note: This can take anything from 20 to 100 miles) At that point, the ECU has adapted to your fuel and you are ready to datalog. For us to be able to analyse the way your vehicle is running, and tune it remotely, we need to be able to access some data from your ECU which will allow us to develop a picture of how your ECU has adapted to the new tune and the fuel you are using.įor best results, please monitor the parameter called “Oct Adj Ratio Lrn” and continue driving normally until that parameter reaches the figure “-1.00”. This is an ongoing process and the numbers generated day to day can be a little unusual to the untrained eye, with spark constantly being added and subtracted to keep the engine operating under optimal, safe parameters. Your engine management system uses its wideband lambda and knock sensor feedback systems to constantly tune itself to ensure that it is operating at the optimum fuel and ignition settings at all times.
