Help with Autocal uploading a tune

[smoken02]

I bought an Autocal with a Tow Delete tune. The instructions start with “Once you have unlocked the ecm”. How do I unlock the ecm? The instructions don’t say and apparently the Autocal has the ability to unlock the ecm so I don’t need a separate device. Anybody used one of these on a 13-17 Cummins?

Just flash the tune onto the truck. It will unlock the ecm during the flash if it has one of the few recent software updates. If it is from a tuner who is running old software for whatever stupid reason then you will need and edge or bully dog to unlock it.

Ok great thanks. It should be the latest software from Anarchy.
