This is a true standalone system that eliminates the use of the factory ECU. The use of this adapter makes the kit “plug and play” so no cutting or splicing wires is necessary. The base configuration files available for the Infinity EMS are starting points only and will need to be modified for every specific application.  \nThe available Infinity EMS part numbers for this adapter kit are: 30-7106 INFINITY 506  \n30-7108 INFINITY 508  \nPlease read this document in its entirety before attempting to start or run an engine .  \nGETTING STARTED  \nYour Infinity EMS will be packaged with four important documents: Usage Legality Disclaimer, Software Download Notice, Security Code Notice, and an Infinity Quick Start Guide.  \nFirst , read and acknowledge the Usage Legality Disclaimer. Second, refer to the Infinity Quick Start Guide (QSG) . Third, follow the Software Download Notice and download the Infinity Tuner software from the AEM Electronics web site (section 2. 1 in QSG) . Fourth, visit www. aeminfinity. com to register your EMS (section 3.2 in QSG) .  \nOnce the registration process is complete, you'll be able to download the latest firmware for your Infinity. The final setup process is to open the Infinity Tuner software and connect to your Infinity to update the firmware (section 3.3 in QSG) . This can be done once the Infinity is installed into your vehicle-see Installation section.  \nOnce the Infinity is installed into your vehicle and it has been loaded with the latest firmware, setup and tuning may commence.
