2018 Silverado issue

Just got my Trinity EX today updated it using the software from the site only to encounter the attached picture. Anyone have any ideas how to fix this or have encountered this yourself?

Yep, normal.. 2017/2018/2019 vehicles require a special unlock sequence... so what will happen is, when you go to install a tune the first time, the tool will give you a message that "one or more controllers can not be tuned - Contacting powertech for vehicle unlock... you will be notified within 1-2 days" - or something similar to that effect.. so then in 1-2 days (usually within an hour though) you should receive an email (if you registered your tool on diablo's site) that your update is ready.. so then you'd run the Ignition Updater on the tool again, and it will update the tool with the unlock code for your ECM, and then you'd be able to tune the vehicle.

Thank you so much that worked perfectly.
