The drive profile setting is definitely not the same thing as the setting accessed from an OBD tool. While I don't know what differentiates the two technically, I believe the latter ramps up the entire effectiveness of the e-diff, regardless of what setting you choose via the drive profile screen. And I know setting the e-diff to "Increased Traction" via OBD has noticeably improved cornering under throttle. A well recommended change without any downsides.
