How can I tell what software version is in the DME?

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.

I'm sorry I've been a bit unclear. I have the sensors in front of the main cats. I don't have pre-cats in the headers, so no cats in front of the sensors. There are no sensors after the cat, but there are bungs for sensors at the rear of them.

My DME is a 5.2.

The car has been in a wreck and rebuilt, parts have been exchanged by POs so I have no information to go by. The body, and I suspect the DME and all wiring, is from a US car. I know this for a fact because I found a small fortune in dollars and a petstore membership card when I pulled the carpet . The drivetrain and suspension is from a Norwegian car. The Norwegian car may have had an engine swap at one stage, because I suspsect the engine is from a US car.

I have the software version from Durametric, but I don't know how to tell if it is US software or ROW? I don't have the printout here, but I don't remember seeing any clear information on this.
