Interested in your general opinion. I do not think that I can in good conscious move forward with this car.
Can you take a screenshot of the printout?
This report makes no sense.....you got more ignitions in Range 6 than in 2,3,4 and 5.
Number is ignitions decrease as you move up the ranges. You got it all over the place. Range 6 should be the smallest number.
Yes, makes no sense. The number of ignitions has to decrease as the range increases. For example if there are ignitions being registered in range 5 they are simultaneously being registered in range 1 (and also 2, 3, and 4).

Not necessarily so. The classic overrev is when you let the clutch out on a low gear when moving fast.... the engine matches up with the wheels and shoots way high passing the lower ranges really fast.... it could stay there at a high range for a while, then you slam the clutch.... the highest will have the most... not so improbable.

While the engine is up in range __, it's simultaneously adding to the ranges below it, and then adds more as it falls back through the lower ranges. So, an accurate report would always taper, largest number in range 1, smallest in 6.

Bruce, are you sure about that? My understanding is that when the DME is logging ignitions in the higher ranges it is also logging ignitions in the lower ranges. So even though the engine may be in range 5 it’s still logging ignitions in the lower ranges, therefore it would be impossible for any range to have more ignitions than in range 1. And range 2 would have the 2nd most number of ignitions. And so on.

I could be wrong... that is not what I knew to be true.... but.... could be!
I think Bruce is probably correct. This isn't the first time someone has posted an upside down rev report. It may be when you rev out a gear and hit the limiter you get highest range 1's then 2 etc. Dropping it into the wrong gear at high speed obviously gets the highest ranges. I've never seen it proven one way or another how they're logged.
Putting it in 1st at 60 mph or whatever could spike the range 6 and then log the lower ranges on the way down.
The problem is,, this is all just speculation, as is everyone else's. Prying information about this stuff out of Porsche doesn't happen. I couldn't even find what the redline is for a Powerkit (GTS) engine even though the brochure claims higher engine speed. I believe I saw it somewhere perhaps and old Excellence article that said its 7500 rpm's. Good luck verifying it, my SA couldn't.
The only solution to this is for one of you to test it and go to a money shift, for science....and mankind. Not Bruce, he provides too many valuable services as well as entertainment.
