So I just got a PPI on a 2005 997 with 72,000 miles and the DME Rev Range is as follows:

Number of Ignitions in Range 1: 3301 - 2427.9 h
Range 2: 492 - 2427.9 h
Range 3: 109 - 2427.9 h
Range 4: 6 - 2427.9 h
Range 5: 1 - 1069.7 h
Range 6: 1 - 1069.7 h

"Some DME variants do not store ignition ranges" is stated right below the range chart listed
Operating hours counter: 2542.80
____________________

So if there are 3 ignitions every revolution and 120 revolutions per second, the car has been in the rev ranges for 9.17, 1.37, 0.30, 0.02, 0.002, and 0.002 seconds, respectively. Are those numbers acceptable or is that bad?

Also, what do the numbers to the right mean with the "h" at the end?

Thanks for your help...I want to make sure I'm not buying a car that has been beat up mechanically. The PPI didn't show any metal or shavings in the oil.

I think the general thought is that 1 rev in a particular range is an error and not real. The "h" number is the number of hours in engine time since the event occurred.

Looks good to me, I wouldn’t give any thought to buying that car.

Looks fine, these results shouldn’t be the reason to not purchase the car if it ticks your boxes and checks out well. Good luck.

I believe the numbers are the hours at which the over revs occurred. So the last over rev sequence occurred about 120 hours ago, someone correct me if I am wrong.

Car was severerly mis-shifted approx 3,335 miles ago.

Use the DME report to hammer the seller on price.

LexVan

Yes. 114.9 hours ago.

def a small moneyshift but the large number of (assuming) normal operating hours since is a good sign that little to no damage done.

one thing to keep in mind: the engine being in a high range for "only" fractions of a second isnt necessarily a good thing. the damage is done by how rapid the spin up. i.e. these engines can conceivably handle sustained over-redline revs MUCH better than they can handle a split second / rapid spin up (i.e. moneyshift) into redline.

Back in the day, I bet the vast majority of 911s floating around all had money shifts, some with many money shifts. No one cared, we didn't know and it didn't seem to matter provided the car was sound and passed inspections. Now many focus on this and even if it does not impact reliability, it can cause the car to take a hit in value . . . the blessed information age and just a different, more ****, over sensitized mentality these days. So . . . that car is probably just hunkey dory merchantly based on this one single factor, but long term value and liquidity may be impacted.

My 08 C4s had a range 6 at 28 hours. It was another piece of information much like the fact it had 66k on the odometer and they it had a slight oil leak. For me I was buying a 3 owner 12 year old car. You have to get comfortable with the car or move on. It’s a personal choice.

You are getting some bad information in this thread. No this is not a horrible report and the sky is not falling. The range 5 & range 6 are errors and should be ignored. There was a missed shift, yet it was not a big miss. You will always get range 1 & range 2 ignitions just bumping hard on the rev limiter. It was over 125 hours ago. Don’t give it a second thought. A dealer would have zero issue CPOing a car like this. If it checks all your boxes go for it.
