From my understanding, stage 0 is a copy of your OEM tune, or whatever map you were running prior to the cobb flash.
With that said, yes if you get the car reflashed at the dealer then install stage 1+, it should give you a backup of the OEM tune on the cobb. Unsure how it would be named as you would already have a stage 0 on the accesport, but I’d imagine it would be Stage 0 (1) or something similar.
If someone else is more well versed on this, please feel free to correct me.

Also confused bc I switched many time
But when I check the backup file in the computer
Date never change. Still day one when I installed ac
Here’s something I found directly from Cobb on another forum that should clear it up for you:
“To confirm, the Accessport does back up the stock ROM data. The Accessport comes programmed with the stock ROM data. Once you have plugged your Accessport in your computer, the file saves in a locked /secret file on your computer. We do this to prevent any tinkering to the data. All Accessports come with the stock ROM data, so if anything does happen to your current Accessport you will be covered if you need the stock ROM data.

When you uninstall the Accessport it will automatically remove the COBB OTS tune and write the stock ROM file back on the ECU.

Stage 0 is the stock ROM data but that allows you to marry the Accessport to your [car] so that you can use all the cool COBB Tuning features.”

How I understand that is when you unmarry your device, your first backup will be reflashed into the car.
