How To Generate EFI Authorization Codes

EFI Authorization Codes

Why do I need to do this?  

In order to purchase an EFI Live Vin License, EFI Live requires the serial number of your device and authorization codes. In order to use an Autocal Device to apply custom tuning, it must be linked to the new tuning company you are receiving tune files from. 

Please note: If you are using an Autocal that has been previously linked or used by a different tune provider, you will need to request unlink codes and unlink the device from that tuning company before adding the new tuning onto your device. 

Generating an EFI Authorization Code

Step 1: Open Up EFI Live & left click on "Check Firmware (button)" in "EFILive Scan and Tune".
