Cheers to all the answers!

Let's see if it improves over time

I also find 1-2 shifts tricky.
It feels as if there is too big of a spread in the gear ratios between 1st and 2nd. Or the revs just drop too slowly.

To get a smooth 1-2 shift, I usually wait for 2 seconds and then release the clutch into 2nd.

And yes, the gearbox tries to revmatch on upshifts, too.
And it doesn't improve over time

doesn't matter what RPM. you need more practice with MT.

Yeah this is what I resorted to at the very beginning

It gets better slowly but it never feels as smooth as with the other gears

Today I turned DSC completely off and am happy to report that this makes shifting 1-2 a lot better. It seems that the revmatch is causing this strange behavior, or maybe the different fuel map with DSC off?

Every BMW Ive ever owned featured this.. It's usually been made better by the now famous CDV delete... How come no mention of it here? Does the M2 not have one, or not have one that is removable?

I'm not entirely sure to be honest. My Z4MC definitely did and taking the CDV out made a huge difference. I will do some digging on this.

And man, if you think the M2 is clunky, the Z4MC is so much worse even with the CDV delete.

Revmatch? You mean the automatic revmatch feature on downshift? How would that possibly effect the 1-2 upshift?

Seems to be absent. You have to wonder if that odious little piece was so valuable to the functioning of our cars all these years, how come now all of a sudden its deemed expendable?!

Revmatch also works when upshifting. On my car the gearbox shifts just fine with DSC off, in any other modes it is acting strange. So it should be either revmatch, the fuel map or both.

Revmatch on upshift? Ive never heard it described as that. .Besides, dont you usually accelerate into the upshift gear change? I dont quite see how an automatic rev match on up shift would work. Does it blip the throttle while your actively engaging the pedal?I guess this is getting rather confusing to me.

It stops the revs from going further down, then keeps the revs steady for a second.
Note that mine is an EU model and might behave differently from a US one.

This!! I've been driving the M2 for about a month now and was also having difficulty with 1st to 2nd.

I finally began to slow down my 1st to 2nd shift and let the RPM drops before letting the clutch out and applying gas. Super smooth!

Once you get used to it, you'll be able to speed things up. Start slow and work your way up.

I've driven around for the last week in DSC off. Much as I like the way the rev-matching works most of the time, turning it off does reveal what a sweet, communicative clutch the car has (and yes no CDV). I found trickling in traffic the rev-match and anti-stall is at odds with how I might choose to drive and I can do a better/smoother job much of the time. I find gentle starts are smoother with it off and coming back off the clutch at rolling speeds easier to manage also. Likewise the 1-2 change is more flexible.

Oh and the diff makes driving with DSC off so lovely.

I find Comfort a very useful mode in medium-density urban traffic. Easy to drive smoothly, exhaust and pops are more hushed and the car is still plenty responsive and brisk. Each mode has its moments , strengths, weaknesses and purpose. I do think full personalisation and an ability to memorise a chosen setting between journeys would be helpful.

Good to hear it gets better... I am facing the same issue with my LCI - I have to wait a good 1-2 seconds before letting the clutch out 1 -> 2. Meanwhile the car behind me is literally on my bumper.

From what I've gathered, the ECU is programmed to hold the revs for emission purposes, as suddenly closing the throttle will cause a spike in emissions. The downside is that the revs (especially with the large difference in ratios between 1 and 2) will not be at the correct rpms for a fast shift.

I think I will practice slipping the clutch 1 -> 2 and shifting before 2k rpms so I don't have an awkward 2 second acceleration gap at every stoplight.

The only way i get a smooth change from 1st to 2nd is if I let the rpms fall enough, quick shift will result in a clunky change like OP says.

While i agree that each mode is intended to
Have its own usage , this is extremely hamstrung by tying auto rev match to certain modes. That feature should be independently switched by the user , or at the least it should be available to be turned OFF in more than one mode.

The delay issues from auto rev match are an interesting issue indeed. Perhaps this will help
