- Controller Authorization Code
Customers tuning 2017+ GM vehicles may purchase a Controller Authorization Code to negotiate controller security prior to reading or flashing their controller.
A controller auth-code is a 24 character code split into 6 x 4-character sections.
Controller auth-code orders do not fulfil automatically. Orders are processed during regular New Zealand business hours. Controller Authorization can now be managed automatically using V8.3.5 software. If you choose to update your software and firmware you no longer need to purchase a controller auth code.US$50.00
