Hi guys....I am looking at a 18 GT3 with the rev report below. I wanted to get peoples opinion on the report. Would this be a buy. One thing I will add is that the car has 3000 miles. Should I be concerned that it wasn’t broken in properly? The over revs happened in first 2000 miles.
No I have no idea. The car has had two owners and the over revs were all from original owner who had the car for the first 2000 miles. The 2nd owner records zero over revs in any range.
Since there are only 62 ignitions in Range 1 and only 2 ignitions in Range 2, it almost seems like the Range 2 ignitions are unreliable (false positive glitch). I haven't done the math, but I'm not sure if you can reach 9,200 rpm if you only record 62 ignitions between 9k and 9,200 rpm... Ignitions pile up awfully quickly above 9,000 rpm...
I think this is why Porsche generally says not to worry about Range 1 and 2.
Seems pretty innocuous to me (I wouldn't worry about it) - seems like the result of hitting the limiter, rather than choosing the wrong gear on a downshift.
Is this a PDK or manual car?
Those in range one are most likely just tapping the rev limiter. We all have done that with no ill results. The money shift on a manual gets the 3-6 range and future issues.

ok so i just read that there are 3 ignitions per revolution, so I understand what you are saying. How can you get 2 in range 2 if you only have 62 in range 1. Once you hit 9200+ you should be well about the 62 ignitions of range 1....correct?

That was my thought. In any case, less than one revolution in Range 2. Porsche would easily still offer Certified Warranty on a car with those numbers. If it doesn't bother them, it shouldn't bother you...
If there are 3 ignitions per rotation and 150 rotations per second (at 9k rpm), then there are over 450 ignitions per second in the over-rev condition. So, 62 ignitions means between 1 and 2 tenths of a second in over-rev.
And it’s possible that the car hit the limiter on multiple occasions and cumulatively has just over a tenth of a second in over-rev (the time of over-rev is given as the most recent, doesn’t imply there was just one).
