Loading Base Session
There is a provided base session that must be loaded into the Infinity EMS before attempting to start or run the
engine. Before the base session can be loaded, the EMS firmware must be updated (section 3.3 in QSG). Once
the process of updating the firmware and loading the base cal has been completed, the setup wizards will need to
be reviewed and the ignition timing will need to be synced.
1. Connect USB comms cable between ECU and PC.
2. Turn ignition switch on.
3. Open InfinityTuner; connection status should be green and indicate ECU type.
4. Open an Infinity layout: Layout>Open Layout. Layout located in My Documents>AEM>Infinity Tuner>Layouts.
5. Upload base session: File>Import Calibration Data. Base session located in My Documents>AEM>Infinity
Tuner>Sessions.
6. After session has loaded, turn ignition switch off, wait for main relay to click off and then turn ignition switch
back on.
7. After comms have been reestablished, review Setup Wizard: Plug-ins>Wizard>Setup Wizard.
