I have a Durametric with software version 6.5.5.12 and ran it most recently on January 26th on my GT4. It fetched over-revs just fine. I keep an eye on this because when the car was new to me I did do one suspect shift which resulted in 67 range 4's and 13 range 3's and 18 range 2's. Those were all over 156 operating hours ago though so maybe that 170 milliseconds or so of range 4 excursion won't bite me So far so lucky I suppose. Oh and I'm not babying the car either -- there are over 850 range 1's that last of which was in September, last time out on the track.

Hi boxer-11,
Thanks for the update that you are able to read the over-revs. I have the same version of Durametric software installed. Hopefully this turns out to be a quick fix from Durmetric.
From another thread the question came up that even though the Durametric can read over revs, does it assign them to the proper GT4 ranges.
Has anyone compared the report with a Porsche PIWIS report?
Here is the response I received from Durametric when I requested an update on my issue:
"When the tool sends the request to the car, the car responds with a "00" response; the tool displays this information to you. We are researching the requests further. Once we understand the trouble we can take appropriate steps. At this time we do not know when a resolution, if any, becomes available."
I have asked for whether this issue has been seen before and when does Durametric think they will know if they can fix this issue.
This is disappointing as one of the main reasons I purchased the Durametric was to check for over-revs on my car. Durametric even confirmed before I purchased the unit that it would read the over-revs on my model car.
I also called the vendor I purchased the Durametric from and they stated they have heard that other people with 2015 and newer Porsche have reported that the Durametric does not always communicate with their cars correctly. Given how this is 2019, I have to assume this issue has been known for a while.
Hi All,
Durametric has not provided any updates to this over-rev reading issue since the last update I provided in Feb 08. Disappointingly, I have returned the Durametric unit for a refund as it does not work as described.

Mike C,
Thanks for the update. My car is at the dealer now getting aligned, and I asked for an over-rev report (wanted to baseline it going into the season), and they are charging me $90!

It reports 6 ranges as discussed earlier. I still don't understand why my Indy gave me a report with only 2 ranges but in any case I had a perfectly clean report. I did not try resetting any service reminders but they all showed as available. I just don't have any to clear so I can't test it.
If anyone is having trouble with their Durametric or hesitant to use up a VIN, I would recommend the latest software 5.5.5.11 without hesitation at this point. It looks like the latest official release is still 5.5.5.9 on the support page. I can PM anyone the link to the "beta" software download if they want it. Or you can contact support directly...

Over-run Report:
After my 2 track days I thought for sure I would at least have a Range 1 over-rev but it is completely clean. I revved to about 8k a few times (as indicated on the RPM gauge) holding gears before entering corners but I never hit the fuel cutoff at any time. I figured that would show as a Range 1 based on rev ranges for other vehicles but I guess the GT4 has higher limits. I am not complaining. Maybe I am just slow
lit you activate the rev limiter you will definitely have at least Range 1 over revs in the DME report, and maybe higher ranges depending on how high the RPM goes above the rev limiter trigger point.

Not necessarily. Since I have heard the same said on this list on several occasions I asked for the dealer to pull the report last time I was there. I know of a few occasions where my rev limiter kicked in (not on downshift) and my report is still zeros in all ranges.
Though, each time was quite short and I don't make a practice of using the limiter.

I second that comment. I believe the display that was shown also indicates that the Durmetric is not reading the over-revs. I believe the 'Product number' being all zeros is the red flag.

Hmm. If that report was done by a Porsche dealer after you bumped the rev limiter and you got zero in Range 1, that is a learning experience for me. Thanks.

I will look for the report, but yes after clearly hitting the rev limiter on a handful of occasions all ranges are zeros. Though, I do usually not try to extract the nth out of my car while on track.

So far so lucky I suppose. Oh and I'm not babying the car either -- there are over 850 range 1's that last of which was in September, last time out on the track.
