Ok, so i have seen a few reading in 6 & I have always just thought it was a glitch, but I have never seen it with consistant over revs in 1,2,3,4 &5 before, so how can this be possible, & what implications does this have for manuel cars showing high rev ranges?

I'm not interested in people telling me to leave the car alone, it's not mine, I just want to know how this can be possible?

Hi,

Okay the only way that this can be done is when on downhill you shift up at max rpm in manual mode, you can go pass the rev limit, and certainly on a 997.1 turbo, you can bounce the limiter as it does not change up automatically from 2nd to 3rd.

Either way, I think it is total Bol%$$$ so it wouldn't worry me if the car had it.

Could a spin on a track also cause it?

Has that engine always been in that car? Can the TCU be flashed to prevent it shifting at the redline?

TCU can be programmed to do anything - for example we can increase RPM and remove final RPM for top speed.

When I asked how a Tip could log over revs above range 1 and I was told this could happen if one was going down a hill, I would guess a steep hill.

I'd have to see the entire over rev range counts and time of events though to perhaps be able to do a meaningful sanity check of the numbers.

Sincerely,
