Default OBDI PCM Issues?

Ok guys, I hooked up my new cable and still have "Data Err" issues in datamaster. I have made a recording as I am now getting DTC's flashing all over the place very quickly and I am starting to think that my PCM has issues. The car runs great, however this whole thing started about 3 weeks ago with the PCM showing false knock and now I see this. Take a look at my attached .UNI file recorded in Datamaster as this was recorded only at idle for about 5 mins and I am showing the following DTC's flash on and off very quickly:

24, 65, 34, 82, 22, 44, 27, 41, 80, 48, 44 and 83

Half of these are Transmission related and I have an M6?

I think my PCM is going bad or has issues, any one else have any advise?

(PS: I know my BLM's are split as that is largely do to the fact I havn't driven it to help level out the LTcounts and also my cam size on a 108lsa).

Ok, update.

Swapped out the PCM with a spare I keep on hand and still not luck - SAME ISSUES. I'm leaning toward the grounding strap (driverside head to body) as it looks pretty corroded and I'm going to replace it today and see if it helps.
