Customers tuning 2017+ GM vehicles may purchase a Controller Authorization Code to negotiate controller security prior to reading or flashing their controller. Specifically the end user must provide the response (the key) to the controller’s challenge (the seed). The seed and key are managed by the dedicated Authorization module contained in the EFILive V8 Tune Tool.

A controller auth-code is a 24 character code split into 6 x 4-character sections split up by hyphens. e.g. ZKWS-6Y95-Q8ND-T23K-4XSX-PQK8.
