I don't know about a tech 2, but diacom stores that data (on disk)
almost exactly how it comes off of the ALDL connector, so knowing that
and the exact datastream definition for the vehicle in question you
should be able to figure out most of the datastream.  I suspect that
the tech 2 may add a few tag bytes (time/date or something similar) on
each frame, but that is probably all.    No one seems to go to alot of
trouble to complicate things too much, it is generally just not worth
it.
