I believe TT's database file contains the definitions for each OSID. There are a LOT of different OSID's used in the various 3800 tune files produced by GM over the years. I've been told by people in the "know" that there are hundreds or more different 3800 OSIDs in existence, and not all of them are supported to as much of an extent as others (within the TT software). This would be the reason why some - with certain OSID's, would see the cat diagnostics showing up in their TinyTuner and others would not.

If one can do a full write and change to a different OSID in their PCM (one that TT does have the cat diagnostics supported in), then that is certainly an option. But not everybody is going to be able to do that.
