Question on Rev Matching

Question on Rev Matching
I have found myself placing the car in sport mode more because I like the sound of the PSE.
Overall, I like the rev matching feature. If I'm going slow, it's nice to be able to slip it in gear with a nice little blip. However, I find myself blipping the throttle when I'm driving faster or more aggressively and it seems that it just masks the auto blip. Doesn't unsettle the car at all.
Stupid question, but is there any downside of blipping over the auto blip?

Given the testing the transmissions go through it is hard to believe that Porsche do not have a default set of instructions when this takes place. The gas pedal overriding rev match makes sense; however as an offender, it would be nice to know what the sequence is when the MT PDK gets 2 different sets of instructions?

Apparently in the R you can disable the auto-blip. I'm sure the manual will be retained in the 992 and it will probably have this disable feature.
PCNA reads these threads, hence the GT4, GT3 Manual, R etc etc etc.
My understanding is the only way to disable the auto-blip is to turn PSM off, which probably isn't a great idea for the street.

Old habits take a while to die..
I too was manually blipping throttle from previous manual cars over many years. I am usually in sport or sport + and the ECU does a better job than me and it never forgets. I have just gotten to the point where I let the ECU do the rev-matching with no duplicate effort on my part. It took a bit less than three months of DD to get there.

I love matching revs myself. Thats 80% of the fun/reason for having MT. Wouldnt buy a car that does it for me. I've been doing it for over 40 years!

I do not know why they changed it but....
In my 991.1 the auto blip on downshifts was only in SPORT + mode. In SPORT mode, this was turned off.
Now in my 991.2 the auto blip feature is on in SPORT or SPORT + mode.
I have gotten used to it and like the feature. However, when I drive an older car for a few days (964, BMW 2002), I find myself manually blipping the 991.2 on downshifts and overriding the auto blip. Takes my brain and muscle memory a few miles to adjust.

In the 981s, the auto blip in sport + mode can be disable by disabling PSM. It's a little known trick. I'm not sure if it is the same in a 991.2. You should try it.

I worry that auto rev-matching is just the Porsche engineers pushing those of us who rejected the PDK into their direction. Us old timers might also remember the Sportomatic. The driver simply shifted the lever into the desired gear, and the car took care of clutching, etc. No real skill required!

I claim 54 years.......1958 TR3, acquired in 1963 at age 18. That car required double clutch downshifting. I liked the rev matching in my Cayman because it was so accurate, but like Subshooter said, it was disabled in Sport mode. My new 991.2 MT didn't have sport chrono. I was disappointed at first, then I modded the gas pedal and all is well again blipping myself.

Ok, we are all showing our age here...
I too enjoy a 3-pedal car and have owned very many over my 52 years of having a drivers license. Some of my most fun came from revving the pedal to shift without engaging the clutch. Every car before this one never had rev matching so the throttle blip became second nature. Since the 991.2 with SC delivers rev matching when engaged in sport/sport+, I find it fruitless to throttle blip over top of it. I believe the main reason for rev matching is to reduce stress on the drivetrain. Sure, it may be fun to manually blip the pedal but I also believe that the ECU does a better job of finding the optimum rpm rev for the gear/speed conditions. My foot certainly is not calibrated in that respect.
Bottom line, it's all about personal preferences and we are all fortunate to drive these amazing machines.
