What is this RPi stage 3 package you speak of, I thought the highest you had was stage 2?
That seems quite slow for shifting...I thought SMG was spec'ed to shift at 80ms (0.08s)? DCT is 20ms, IIRC.

Randy not saying it takes long for the SMG to read the shift but the actual shift itself takes around .5 secs as this is what I saw from one of my vbox runs below.

Hrmm...but I thought BMW had advertised that the fastest shift speed in S6 with SMG is 0.08s. Unless I'm understanding it incorrectly and what they meant by that is the time it takes for the SMG to read the shift?

No problem. Was just hoping someone was knowledgable enough to explain why there is a ~10x difference in shift speed.

i take it these are third and fourth gear shifts they should be much quicker thats an odd occurance? im sure you had your setting correct and your car was warm ect...m i wonder if somehow the sc is messing with the timing of the smg somehow possibly smg tune related? maybe its a way to smoothen out your shifts since you have so much more power? i can only speculate but thats really weird. has the smg shifts felt slower since you got the sc?

SMG slows the gear change as you approach the rev limit (standard) for safety and it discourage you from pushing that hard so if you now raise the rpm limit theres a bigger window of the slow changes. Try it: change at around 8000rpm= really fast 8250=slow(er)

I believe the SMG will need retuning to change this, may be the ESS SMG tune?

That is some slow shifting. I just got my vbox yesterday. I will try to get some runs in from 60-130 with my raised limiter so you can see the difference. Problem is it is @#%@%#@ cold here right now. It isn't as easy to get runs in as some of you think. I have to deal with traffic and the fear of getting getting a ticket.
