1-2 in virtually any MT is difficult. Its just timing. Redline shifts everywhere else are butter!

You're not alone. I've done it on a few occasions. Talk about cringe worthy!

3rd...I have grinded my gears a couple times power shifting from 1-2. I learned to smooth that out and hammer the rest of the gears.

I am also running the numeric racing shifter with Function First weighted ****. My shifter feel has become worlds better than stock.

for me the big difference is between normal and sport... i find that the throttle response in normal is much more forgiving when shifting up at high revs in first

I have found the 1-2 shift somewhat rough in both my 991.1 base and my 991.2 S. I thought it might be a faulty synchro in the 991.1, but have now accepted it as normal 991 behavior since I find no difference in the 991.2.

It is not, however, common to all high performance MT cars. The 1-2 redline speed shifts in my 1994 6-liter 6-speed Pontiac GTO, for example, were pieces of cake, even with 400 hp and 400 ftlbs of torque,

As an aging early 60's vintage hot rodder with fifty-eight years of speed-shifting experience, I am just a bit disappointed with this aspect of Porsche transmission design.

Mine definitey got better after about 5k miles (and the clutch seemed less grabby, too).

And I agree about muscle memory. The shift action did not seem inutive at first. Not bad, just different.

Mine is now butter smooth at 1800mi. It was somewhat notchy for the first 500 miles.

Unless you're a pro-stock drag racer, you're over thinking the subject. How often will you do a full throttle, redline 1-2 shift? That's what dual clutch launch control is for.
Admittedly, my 911.2 GTS MT has smoothed out noticeably now that I have ~2.6k miles on the clock. I've been driving manual transmissions for many, many years and have found that each car has it's unique feeling and you need to adapt your technique to accommodate it. Once you've "bonded" it's pure joy.

Yes, mine started out stiff as well, and that's expected. With 10K on the odometer, it is smooth as silk. My main problem early on was hitting the rev limiter a few times. I wish there was a heads-up display available. I have a C2 and can't imagine keeping a MT "S" off of the limiter.

The MT is 100% better/smoother going from 1-2 in the 991.2 than in my previous 997.2. This after only 800 miles on the odometer. I expect it will get even better as it breaks in.

Dual clutch launch control has nothing to do with shifting. It is designed to produce the quickest possible start from rest. And if you ever pull up next to a Corvette with an empty road ahead, you might well do a full-throttle, redline shift from 1-2--and 2-3, 3-4, etc.

To me, it seems like the engine drops a lot of rpm between the 1-2 shift, especially if you are just lollygagging in traffic. I blame a light flywheel. Seems my shifts are smoother if I rev higher and shift faster.

If driving like a pedestrian, I skip gears when in normal slow traffic.
1-3-5-7 to loaf along at 50 mph.

Today I noticed during higher load upshifting from 1 to 2, the revs continue to climb for a very brief moment even after you let go of the accelerator and depress the clutch (its like the engine holds on to some momentum). You need to have a sloow clutch release, and ROLL back into the throttle to keep the revs stationary while you engage 2nd...otherwise it grabs 2nd too early and the engine briefly cuts power, resulting in a jerk...
Slow clutch release with gentle roll into the throttle immediately after the revs start coming down seems to be the way to nail the 1-2 shift.... for me. When you nail it, its like a slingshot. Truly rewarding!!
PS. This shift cannot be done as quickly as the other gears. 2-7 shift as smooth as the pdk, at least with rev match on. I can do it myself but its like molasses in comparison.

DanQ

We seem to be saying different things, but your key point of holding the revs up to match 2 gear is correct. I don't think you HAVE to shift slow, if you are holding 2nd gear rpm. You can shift slow or fast if the rpms match.

Rennolazine

Good point. Maybe im rolling into the throttle too slowly. Or maybe the clutch (and my foot) just needs to break in more
