When you connect the Durametric the Engine summary page has the DME software version.

What year/model is your car?

No rear O2 sensors? I wonder if that is still a stock setup?

If not, I have seen rear O2 sensor simulator circuits that emulate the signals a rear sensor would produce so that the codes go away.

Or you could install your own by welding a fitting somewhere downstream of the CAT's in the exhaust pipe.

I think the 986's only had the 2 DME versions 5.2 and 7.2 if I recall correctly. Not sure exactly when the transition took place (~2000?) but you will be able to tell from your Durametric readings what you have.
