Automatic Rev matching on manual tranny
appreciate feedback from anyone that has the downshift rev match feature. Do you have to blip the throttle to initiate the rev match during a downshift, or does the rev match happen automatically when the clutch is engaged during a downshift?
Are you happy with feature and do you use it regularly or leave it disabled?

Happy with the function. I use it about 50-75% of the time. The rest of the time the car is in Sport. It's a neat little function, especially so in combination with the other Sport Plus settings.

I drove a new C4S Manual w/ SC last week and it absolutely sold me on the 911 C4S. I haven't been much of a fan of the 991 from the launch, but it was growing on me. But this feature makes all the difference (to me):
1) For city driving, it makes those downshifts at intersections much easier to perform and a MUCH smoother ride for the passengers as there is NO jerkiness due to a poor downshift.
2) As great as it is to be able to heel/toe, that is a skill probably best suited for the track and not the street.
3) The throttle-blip is managed by the computer, so the EXACT throttle input is delivered for the needed engine speed. I don't care how good you are at Heel/Toe, you can't be as precise as this feature is.
4) Unlike PDK in Sport+, Sport+ with the Manual does not make the shifting very abrupt as you are still shifting the gears and delivering throttle input. S+ does make the throttle more sensitive, put the suspension in a firmer setting (which can be turned off) and opening the Sound Symposer...but it does not make the drive rougher...just more sensitivity to driver input.
If/When I move to a 991 C4S, it WILL be a Manual with Sport Chrono and I WILL drive it in Sport+ all but when my wife is in the car...which is rare.

Early 2013 build maybe? I thought the 2013's S with sports chrono had this feature.

Rev-matching came standard in my 2013 911S with SC; it works quite well.

Drive it in Sport Plus mode, downshift gears and if the car blips the throttle for you to meet he revs of the lower gear, then you have it.

I was under the assumption that it was all 991 MT's. It looks as I might be mistaken.
But one might wonder:
Why put a track feature on a S with SC, when people who track already do this? It seems as though who would benefit are those who do not already do this - i.e., those who don't track regularly (non-S or S without SC).

I wonder. Perhaps, there will NOT be a way to disable it, because rev matching may improve the life of the transmission.
I wonder what happens if you do it anyway - it seems as though if you blip, the ECU would override the input, using it's own program anyway. Allowing you to go through the motions, without causing any damage (for possible over rev or under rev during clutch reengagement).
