GM Controller Auth Codes

Authors list

Controller Auth Code purchases via the EFILive website are no longer required. The January 2021 release now manages this process from end to end for FlashScan/AutoCal V3 and FlashScan/AutoCal V2 devices.

In addition to the cost saving of $50 for the controller auth-code fee, there are significant time savings for tuners and end users. Auth codes no longer need to be transferred between tuners and end users, and a secured controller that has not yet been unlocked will now read completely in a single step process.

This is a free enhancement for all customers who update their software and firmware to the January 2021 software release or later.

Where a customer purchases an auth-code through the EFILive website prior to updating their software/firmware a refund will not be available.
