To completely uninstall the version 2 or version 3 Accessport, you must select the Uninstall menu option on the Accessport (and confirm that the process completes). This will restore the ECU to the image that was backed-up during the install process. If you instead change to the "installed stock mode" map, this is not the same as the uninstall process.

When you reflash a map (when you change maps or install/uninstall the Accessport), the ECU will be reset. This happens regardless of the solution you use to tune the ECU. This is basically the same as if you disconnected the car's battery or reset the ECU via an OBDII scanner. The dealership has the ability to tell essentially when the ECU was last reset. So, depending on how much of a leap they are willing to make, they may infer that you had some kind of tune on there, even though this is not direct evidence. If that is combined with other evidence of hard parts mods (downpipe or intake) or evidence that mods were removed (ex. marks on downpipe bolts/nuts), that may increase the chances of a denial of a claim.
