Yeah, there were some guys over on the local DSM board who were using this or something similar. They said it was not all that accurate, but still fun to use on the side.

There's another app out there, Dynolicious that just uses the accelerometer to estimate hp, 0-60 and other stuff. This is different. The free version offers up a G meter based on the accelerometer and a track tool thing that uses the GPS to show accel/decel on chart based on location. Its pretty weird to see but its supposed to be useful to driving around a track, showing you how you take the corners or something.

The OBDII reader part isn't out yet though.
