So I guess you aren't 100% confident that there can be no ovverrev in a stock tiptronic/pdk car.

Just kidding.

 

Many discussions regarding this topic at Rennlist too. One of the posters doesn't think that inertia comes into play and is convinced that the rev limiter will prevent an over rev, stopping the engine's rpms at the limit, no higher. Maybe we're more enlightened in this forum.

 

Thank you Skandalis
THIS is my point. But others in the thread won the semantics war

 

In manual mode with sport mode on, car will not atomically shift up. It will bounce of the rev- limiter. In full auto mode, with sport mode on or off the car will shift at redline. Seems like it would be hard to over rev the car.

 

However you can twist semantics into saying you do because EVERYONE that has a remote clue about cars knows that the car shuts the gas off AFTER you hit the limiter there is still power being developed so you will go over the limiter for .000001 of a second but you went over it so they are right

 

Agree this is a likely scenario for an over rev to show on a Tip, even though i hear the tip has a slightly lower red limit of 6600 than the manual. Not sure if the range 1 counter is different to accommodate for that difference?

Skand as you point out, in a first gear wot shift up to the limiter in manual mode, even after the precise point ignition is cut the engine will still have a degree of inertia to throw it further past the redline and into the over-rev range. So a tip can never fully immune to an over rev spike.

A tuner may possibly be able to answer exactly what deactivates when the limiter is hit eg: spark, fuel, throttle body valve etc. It would be interesting to know whether the butterfly shuts immediately. Regardless, it would be hard to imagine the engine spinning on much more than 4 to 500 rpms at most, least of all 1000rpms pushing it into the range 3's. And agree a range 1 or 2 is hardly likely to cause any damage anyway.

 

Right but there are 6 levels of overrev. The levels the tip "allows" which most tuners tune too and past. So while its an overrev... its not a harmful one persay

 

You are right about the stock tip they won't overrev to range 3 or further. Range two won't cause any damages. Just make sure u have all the reg services done. Oil level is within specs.
