That's exactly what the rev limiter does. It protects the engine when you're in say 3rd gear and accelerating. It stops you from damaging the engine if you go too high with the tachometer and you don't realize it.
BUT, if you shift into the wrong gear, say 2nd instead of 4th, you can overrev the engine and damage it.
Range 1 and Range 2 ignitions can show up on the DME scan when you hit the limiter and the tachometer bounces back down to the normal range. This is what you want to see. I won't buy a car with Range 3 or above ignitions based on my experience.
If you money shift the car, Range 3 and above can show ignitions (Range 4 and above is all you need to worry about). This is the whole premise of the overrev report in the first place: to see if the car was driven properly.
Some cars will vary, especially if they've had their ECU flashed, which can move the limit around, as Dr. Bill pointed out.
The DME scan is only one piece of the entire puzzle but it can tell you how the car was driven and give you a clearer look into the car's history.
If you do see Range 3 and above ignitions, it's generally accepted knowledge that once you hit the 50 hour mark after the overrevs took place, the engine should be fine as it hasn't failed up to that point. 100 hours past the ignitions is playing it super safe if you're worried.
A good example is if a Turbo was on a dealer lot and was taken for a test drive shortly after being delivered and was money shifted. This will show up as ignitions in higher ranges but the hours of operation will be somewhere around 25 or so (just an example). If this same car has had several owners, the overall hours of operation will show 1200 (another random number for our example). You have nothing to worry about because the engine has seen 1175 hours of use since the overrevs took place. This means if the engine was going to fail, it would have failed in the first 50 hours following the overrevs. You're now well past that 50 or 100 hour mark so you have nothing to worry about as far as catastrophic engine failure due to redlining.
This is how the overrev report should be used to understand what conditions and type of driving a specific car has seen. You can use this info to make your own judgement on whether or not the car is going to need a new engine.
Without a DME scan, you're taking a gamble on whether or not you're getting a car that's been abused.

Great explanation. In summary, hope this is accurate: Shifts to electronic rev limiter won't trigger anything above range 2, therefore no big deal as it's not mechanical. Ranges 3 and above are mechanical in nature, forcing the engine above the limit. For range 3's and above, 50 hours after should be enough to feel comfortable.

John,
Looks really great! Good luck with sale. Whoever gets it will be very happy. I just bought a 997.2 GT3RS from John. Very pleased with the car.

Good question. Do not know how to answer this. I would ask John Wright at Porsche North Houston or Doug at Switchcars. Doug now owns my car. They both are very knowledgeable about Porsche GT cars. I have heard Doug refer to this as a 997.1.5

2009 Turbos are considered 997.1 with an updated PCM.

You can also tell it is not the newer version, beyond the applicable taillights etc... as it would be listed for an additional 200k. The 997.2 was only available as the GT2RS, and in limited number release. Epic cars in both versions.
