Can losing PCM sync with datamaster indicate a bad PCM? This is for the 95 Z28 in my sig.
I actually was getting DTC 13 (driver's side O2 malfunction) and I went to swap the O2s (driver's side to passenger side and vice versa) to see if the DTC code would change (bad O2) or stay the same (wiring issue). I also did check the wiring from the O2 wiring to the PCM and got infinite resistance even with the engine warm (wtf?)
Now I'm not getting a trouble code at all and I do have a "new" PCM and it also keeps losing sync with datamaster every 9 or so seconds.

If you use the Corvette settings it works but sync problems are common.
Set F-Body car and try again.
A few sync errors are normal, many are not
