I have a 7MT and I have driven it in sport plus mode since I picked it up (love firm, solid feel). I was getting pretty bad gas mileage so I decided to try it in sport instead to see if the mileage would improve. When I did that, I found that the rev matching did not occur. Now, I've never had rev-matching before and usually I rev match myself but since I've gotten the 991, I have gotten accustomed to it doing it automatically. I actually did not try driving without sport or sport plus since that would bring the stop-start mechanism to come into play. I was wondering if the rev-matching always occurs with the PDK regardless of whether or not the sport or sport+ buttons are pushed?

rev matching only on with sports + (from what i understand)

7MT - rev matching only in sports+
PDK - all the time. In normal mode you don't really hear/feel much though, because of the fast shift time and close gear ratios - it's like the engine RPMs simply jump higher.

Rev-matching with manual is only in sport-plus which you only have if you get the sport chrono.

I have a 2013 7MT with sport chrono but apparently got it before they starting including the rev-matching feature as I don't have it.

Initially I didn't like the fact that I didn't have it but after thinking about it I believe I would find it difficult to have it operational part of the time i.e. when in sport-plus mode, but not sport or normal.

Once you get use to rev-matching yourself I think it would be hard to suddenly not do it when switching to sport-plus. It is sort of an involuntary reflex after a while. I am sure the opposite would also be true if you normally have it and then switch it off by leaving sport-plus mode.

I guess you just have to pick the way you want it and leave it that way.

I wonder what the purists have to say, that heckle us PDK drivers for not being worthy of driving a Porsche sportscar, about the purity and involvement of autoblipping on the manual in Sport+ ?

Can rev matching be programed into a 991s 7mt with chrono...?

Both result in ED

That's totally unfair! I believe what we all said was that you're not worthy of driving any sportscar and that it's not a sportscar if it has paddles.

But seriously, I've seen comments about 'why doesn't this have an on/off button or option', which seems like it would make sense. That's clearly a computer managed feature, and a menu that lets you set which modes should activate it should be pretty easy to implement? I could picture wanting that turned on maybe in Normal mode (easier driving in traffic) but off in Sport/Sport+, for example. Why Sport+ would mandate auto-blip... Seems almost backwards?

Sadly I can't imagine that will be retroactively added into the PCM - it's like thinking that instantaneous MPG will suddenly show up with an update. Or GT3 steering mapping?

Yep, Porsche marketing wants to make sure you buy the Sports Chrono Plus option.

mrstep

Certainly, though it would be nice if you could buy some of the electronics tricks à la carte like you can some of the physical options. For that matter, options that would work on the current model that come out for subsequent years. (Understanding that's a different potential scenario than just enabling electronics features from an existing year...)

It would be much nicer to take advantage of the fact that the PCM is a computer, would let Porsche monetize some features across more cars/years, and at least help to offset the fact that any electronics on a car are going to be dated before too long.

Oh well.

I use it to remind me how much practice I need in doing it myself. It is perfect every time.

I enjoy the rev matching and am surprised how the dynamic engine mounts (that also come with Sport Chrono) change the character of the car with the 7-speed manual transmission. The car becomes much, much smoother in Sport Plus mode. Here is some additional information: https://rennlist.com/forums/991/7668...-recap.html#14
