GRID Autosport Support?

Just a quick question regarding the extent of telemetry support GRID Autosport has.  I play it with my friend at his house, and realized I can use my phone as a sort of DDU and nix the HUD completely.

I'm getting lap data (fastest lap, last lap, current lap, etc.) and the like, but I'm not getting any driver data or gaps to different cars.  It's quite possible that this is as much data as is collectible, but I just wanted to be sure.

Anyone who's in the know about support for Autosport on PC, cheers in advance for any insight you may have.
