OK, so got DiagBox happy, plugged it into the car, chose 406R, and then what? It just launches PP2000. So it looks like DiagBox is just a bollocksy front-end. There does seem to be something to do with "measurement" in DiagBox, but it's not giving any clues as to what that is, and apparently you need to get different cables
Anyway, here's the next problem: PP2000 can't see the interface.

Now, DiagBox can see the interface because you have to plug it in and install the driver in order to get to the car select screen.
So, how do you run PP2000 on it's own? Where does it live under /AWRoot ?
