DME data

[bbywu]

Does anyone know if the ECU records not only the number of Type I or II over-revs, but also WHEN they occurred? Is the data recorded as total number of occurrences, or is data also recorded with mileage or hours run during the occurrence?

I'm looking into purchasing another 997, but when I asked the dealaer to run the DME, a few Type I and II over revs were recorded...and the car has less than 5000 miles. I'm worried that the car was abused during break-in.

Any insight would be appreciated.

It's a 2007. Looking at your first link, does the data store the number of hours for the last incident only? The interface doesn't look like PIWiS.

Yes, look at the image Tool Pants posted on the second link.

Range 1 is 7,300-7,500 and Range 2 is 7,500 to 7,700 and Range 3 is 7,701 to 7,900.

So the car was over the recommended 4,000 RPM’s if this occurred during the “break-in” period. A usual rule of thumb is about 35 miles per operating hour, so you can do the math. The DME will show you total ignitions and hours run at the LAST occurrence. If there are only a few, it may have only been one event. The most important thing is will the dealer support the factory warranty in writing knowing this. It’s probably fine, good luck. :)

Thanks Scotto. I went ahead and passed on the cabrio. I'll just stick with my TT.

Hello, new member here. I would love to be able to pull my own DME data, what equipment would I need and how would I do it? Would that also show be DTC fault history and possibly show the recent ECU flashing by GIAC??? I bought my current Porsche as a CPO.

Thanks, Summoboy.

Hi,

Go to the site below to order the scan tool.

I'm thinking of getting the Durametric tool, one question though:

can you use this to open up the options available in the Chrono package? There are some settings I'd love to change, but I didn't see mention beyond OBC. wondering if that's the part of the OBC they're talking about...

:-)

The Durametric tool can not program the DME or any options. It can only reset fault codes and show actual values.

On the newer cars (Cayenne, 987, 997) some options are "chargeable" so they require an IPAS code with a PIWIS tester. I know on the Cayenne the compass option must be paid for before Porsche will issue the IPAS code to unlock it. I don't think OBC requires a code on the new cars but I suspect the Chrono option does. In any event you will need a PIWIS tester to change any programming.
