DME Overrev Readings

[kurteck]

Hi All, Looking to buy an '06 C2S with about 30k miles. The car has seen about 20-25 DEs and the DME readings are as follows: Range 1 - ? Range 2 - 4669 Range 3 - 1200 Range 4 - 52 Range 5 - 0 Range 6 - 0 Should I be concerned? Also, looking for a good mechanic in NJ who can perform a solid PPI. Thanks for your help!

so many range 4's. It's been driven hard and probably by novices. I'd pass.

52 ignitions in range 4 equates to approx 17 revolutions of the engine - IN TOTAL - in that rpm range. That's about 0.13 of a second!

How does that sit with being driven hard? By novices?

I wouldn't worry about that DME readout in the slightest....

^ Agree. Looks fine.

LOL, I was thinking the same thing. I am not a novice driver, and I am sure that my DME is a lot worse! Perhaps that is what he is saying, a novice won't be bouncing high rev's, they are more cautious. I have had it a few times that down shifting and braking hard I have over revved it higher then I care to say!

All I can say is the harder my car is driver, the happier it is! Not one warranty claim on my 06 to date, either it is built to last or it will explode while sitting in traffic!

The DME is probably not that tragic, but it isn't perfect. Depends on the price and condition. The DME readout is only a factor. BUT what is a factor is an owner that has CONFESSED to 20-25 DEs. I always multiply that by a factor of 2. That car has been USED. I intend to use my car, but I buy a car that's been pampered!! DE's put a lot of wear on the car and it already has pretty high mileage for a used 997. Personally, I'd pass, but not because of the DME.

+1 - The harder you drive 'em the better they run!

Strange what you said about exploding in traffic though - that's exactly what my (now scrapped, previous) gearbox did!

Thanks for the advice guys!

I am with RyeM3 on this . You want a car that is as close to being new as possible .

I would not use the number of DE's as a factor, according to my service advisor at the local dealer the cars that sit in the garages, are the ones that have the most problems. The ones that are driven, are fine. Want to guess why Porsche puts a minimum number of miles per year as a condition to the warranty, and no the answer isn't because they want you to wear them out. They have tested there cars and found thar they are made to be driven!

Then maybe you ought to ask him about all those 2009 cars which sat on dealership lots for a year before the Porsche "moment" sale without being driven .

The ultimate garage queens were found at dealerships with the massive 09 inventory which took enormous discounts to sell . They were not found in owners garages who drove them infrequently.

I am sure sitting on there lots aren't the best for the car...good point. The good news is, drive them and they like it! There have been a lot of people that will say a RMS "fixes" itself when it is driven. Last winter I did some mods that required a new RMS, it was switched, and still leaked. The shop that installed it and I agreed to try it and it stopped leaking, and hasn't leaked since...go figure.

There is absolutely nothing wrong with that DME scan. The car appears to be driven well. If the car has a clean maintenance history and it passes a PPI, you are going to have one solid car.

The DE events would have made any "niggles" or "flaws" with the car obvious and if it has a clean maintenance history then you are looking at a fairly bullet proof 997.

I would also ask at what frequency the previous owner was changing his oil. If its at least every other DE/track event then he has been keeping up on his end.
