ECU scan impressions needed.

ECU scan impressions needed.
I'm looking at an X50 996 Turbo and the ECU scan reads as follows:
Number of ignitions range 1 11514/1199.3h
Number of ignitions range 2 56/1196.7h
Operating hours counter 1200.6
The car has 34,112 miles on it so, according to the scan, it has an average speed of 28.41 mph throughout its life.
What do you guys think as far as the engine being compromised or not due to the above range 1 and 2 ignitions and wether or not the mileage seems realistic based on the miles/operating hours?
Thanks in advance.

Range 1 is going to happen because how fast these cars accelerate in first so its bound to hit the limiter if you are a newbie at driving this car. The range 2 however is a different story. That's when the car has been forced to be over revved maybe by someone missing a gear and going to first instead of third on a downshift.

This is incorrect...do a search it has been debated many times and lots of evidence the type 2s can be created several ways. Lots of cars have type 2s with NO issue.

I have done a search and talked to a few service advisors to confirm this. I never claimed a car with type 2's will have "issues". IMO if there are a lot of type 2's it was probably raced or driven extremely hard.

The techs simply advise that the car must be driven, and driven long enough to give the DME plenty of time to make sure all systems are AOK and for the engine to act up, if it is going to, from either the effects of the overrevs or for some other reasons.
How long should the car be driven?
The techs mentioned they'd like to see at least one hour of engine run time since the last above range 1 overrev event.
Make that: ... at least one hour of engine run time since the last overrev event. That's any range.
Unlikely you'll get an hour's test ride/drive with the car but if you work it right the engine may run nearly an hour.
Visit the car cold and be sure the CEL and in fact all warning lights come on when the key is turned to the on position, then go off when the engine starts.
Let the engine idle until nearly warm, or warm enough to check the oil level.
Then have the seller take you out -- with you as a passenger -- on a 15 mile test ride.
The route should allow the driver to demo the car in a variety of situations.
Back at the starting point now as a test driver take the car out and follow the same route, drive the car the same way.
If after the above the CEL is off, if the engine is not making any troubling noises, and the rest of the car checks out, chances are very good the car is ok.
But give that engine some run time!
Sincerely,
Macster.

I wouldn't be concerned about the ignitions at all as long as it runs fine per Macster. These motors, due to their high-compression, will begin showing problems (making noises) almost immediately if there is any damage caused by an over rev. Get a good PPI report and buy the car and enjoy.

56 type 2 ignitions is nothing. That's basically 9 2/3 revolutions, if I understand it correctly, so a fraction of a fraction of a second. (too tired to do the math)
Based on the hours where it occurred it looks like someone took it for an aggressive test drive.

X2 on the type 2 ignitions. Another factor to consider is if the car has a "flash" because with most flashes it raises the redline a tad, hence increasing the number of type 1 and possibly type 2 overrevs.
That DME scan looks fine IMO.
#13
As already posted this is likely an event that lasted less than a second.
#14
For me the most important thing is how many hours since the last overrev. Internal damage can take time to manifest. I like to see a few thousand miles, this car has had 100 miles or less since the type 2.. the type one was minutes ago.

Guys thanks for all the replies. Paint meter readings shows 8 mils all around. The car has 2 new front mismatched tires, the front bumper is resprayed in situ, without removing it from the car - as there were subtle signs of overspray on a headlamp rubber trim (very small overspray but I saw it) - and doesn't align properly and the wheel well liner of the driver side had one of the slots for the air to pass through broken. The front bumper doesn't look properly put in place either.
Those seem to be signs that the car had some sort of frontal collision that was repaired on the cheap. The CarFax is clean but things can be fixed out of pocket, specially if on the cheap. Were it not for the 8 mil reading on the paint, there wouldn't be any signs, however subtle, that anything besides the front bumper has been painted at all. It looks factory and only that paint meter reading raises suspicions. A local body shop - with no affiliation to the seller- said that a portion of factory cars come out with paint defects and are subsequently repainted at the factory all around; he said that it can be the cause of the high reading if there is no evidence anywhere that the car has ever had an accident, done by close inspection.
I've decided to move onto another car because there are a doubts that have a major impact if they cannot be investigated with 100% certainty, specially at a $54k price! At that price it has to be on the showroom in a condition that one would have absolutely no doubts about it.
