How to Find Serial and Auth Code for an EFI Live AutoCal V3 Device?

To view License Status or generate Serial and Auth Code information for VIN License purchases:

  1. Connect your AutoCal device to your PC.
  2. Start the EFILive V8 Scan and Tune application.
  3. Click the F7: Licenses button in the left-hand pane.
  4. On the F2: Hardware tab, the serial number is displayed in the Serial Number field. Copy the Serial Number for VIN License purchase.



  5. Click the F3: VIN tab to display VIN License information.


  6. For VIN License purchases, click the [Generate Auth Code] button. The Authentication Code will be shown in the Auth Code field. Where the available VIN license slot count is zero, customers will be unable to order VIN Licenses until the VIN License slot limit is increased by Tuner Depot.

VIN License Validation Help

If the serial and auth code do not pass validation, an error code will be displayed. Error code details and VIN License validation help can be found here. Customers should ensure that the information entered is EXACTLY as displayed in EFILive software.

  1. Check the software version used to generate the auth code.
  2. Check for spaces at the start/end of the code.
  3. Hyphens are essential.
  4. Serial must be either 10 or 12 characters.
  5. Auth Code must be exactly 20 characters.
  6. Verify quantity limit has not been exceeded.
