I don't think its possible to over rev a PDK

GrantG

It is only possible to do exactly what this manual car did. Both cars can have this sort of over-rev report where someone bounced off the limiter...

Its harmless with manual and PDK ...

great. Thanks for doing the math. Really minuscule.

I think the range 2 are false positives, mine also had 5 range 2 overrevs but then it said max engine speed was 9120 rpm so not sure how it can be a range 2 and sub 9200 thats why i initially asked OP if he knew what RPM they were at

What do you think about 30 overrevs in stage 3 on a manual car?
In 22000 km I never misshifted, the car feels and drives great... But during the warranty extension procedure we (me and my dealer) have found these 30 overevs in stage 3....extension done with no problem...
But I m still thinking about this strange discovery... .

Nothing. Don't worry about it.

Is it possible that it was done during servicing drive by the dealer?

I assume you are the only driver and never recall this event so I logically am looking outside of your domain.


PS - Wishing you and Italian families good health in these serious times - Forza

Thank you so much!!!!

Ps not from the dealer.... the car had 15 km when i picked up

Thanks a lot.......

Don't worry unless Range 4 or above.
Just to add a data point, running to the rev limit in a GT3 will show limited ignitions in range 1 (under 100) and a few false positives in range 2 (less than 10) and a high engine speed in the 91xx range.

This exactly explains my DME as well. Never a missed shift, one brief bounce off the rev limiter. Report shows under 100 in R1, a single-digit few in R2, max engine speed 91xx.

mrhamamg

Same thing here with mine

IORR

great thread!

I once asked my service writer about over revs and he said real over revs almost never happen.

Question- I get the Money shift potential but I thought you can not over rev while accelerating. Does it not cut off/stall if you go above 9000.??

I remember my 997.2 Turbo Manual would briefly hesitate if you redlined so you could not over rev while accelerating

GrantG

It does cut off fuel, but it isn't a totally hard limiter (it has a more subtle cut-off that is a little smoother to the driver and hardware which allows it to slightly exceed 9k sometimes if you keep your foot in it). Hitting the limiter like this, while not to be encouraged, is designed to be harmless to the engine.

If you were to run a report on your 997.2 TT, you might have seen a few Type 1 over-revs as well (even though you don't notice it on the tach).
