For me the down shift from 2 to 1 was most noticeable and my open throttle shifts the kick back was lessen. In my opinion it was completely worth.

Again, you are trying to say "GTS and non-GTS are pretty much same cars". What I am trying to say is that from a product management standpoint they are different models with hundreds of different part numbers. They just can't take one part/software from one product and smack it on another product with the words "see, it fits, so it should be fine".

Were you downshifting from 2 to 1, or even in manual mode were you letting the car downshift from 2 to 1? Ive had a mixed bag of reactions, with no conclusion whatsoever on my part !

As to your shifts under WOT, do you use S2, S3, which mode ? Also do you know what I-step your car has ? Sorry for the many questions, not doubting anything you say, rather trying to explain my experience!

Hallo, Wie geht's?
generally, what you say is true, that testing ($$$) is required for reuse of any software module/class/... onto another platform. Depending on what type of software shop BMW runs, you'd hope that they know that the cost of fixing bugs once in the field is orders of magnitude had they injected appropriate relevant improvements or fixes from the current software development stream (M4 GTS EGS) into the M3/M4 maintenance stream.

Regarding the M4 GTS DCT, we know its 100% identical hardware, clutches, mechatronics, ... with its M4 predecessor, so we'd hope that some common fixes/improvements were ported/propagated to the M4 stream. The M4 EGS received a makevoer (BTLD, SWFL) updates at 59.0, and the main/minor/patch number is identical with that of the GTS EGS as well the BTLD is identical.

Of course, this is all speculation, and have no clue how BMW runs their software releases, but any modern software company realizes at one point in time the merit of a common software stream for a common hardware platform.

Before when I was in S3 sport+ at 2500 rpm my 2 to 1 shifts would bog but now it is smooth.

My WOT shifts feels like a video game now, just constant pull with minimal kick back.

I'm not sure which firmware I had, my car was a 7/15 build and never updated anything. Maybe my jump from an even older firmware than yours gave me a bigger difference.

Ah, here's a difference, I never drive in S3 and I never do WOTs in daily driving ! found S3 too aggressive for daily driving as do others too. I was on a track last Monday and thought about using S3 but didnt like the snap the car does.

July 2015, or 2016? if the former, yeah for sure its quite old software, though nothing can confirm what changes happened in the software updates aside from similar subjective opinions mine was June 2015 before many software updates done.

I think with the GTS DCT you will feel the most difference when your pushing it. Day to day driving there isn't as much of a drastic jump.

Lets hear some feedback !

[M3ryder55]

Interesting

[humbertin0]

Any feedback from guys with ZCP upgrading to the GTS DCT flash?

how much do you charge? (I have coding cable). I assume you can do it remotely via teamviewer

I have a 16 ZCP M3. I just had EAS do the GTS DCT flash on it earlier this week. I didn't think it would be that much of a difference but I was having the car coded and figured I would have the transmission flash done while it was plugged in.
It is a noticeable difference. 2 to 1 at low speeds is much better. Especially when coming up to a light that just turned green, the car just pops smoothly into first gear and goes without slipping or bucking or hesitating. And it would hesitate badly before. Compared to my e92 M3 DCT this new f80 M3 DCT felt sluggish and hesitant at lower speeds and take-offs. WOT shifts were about the same between the different generations but I felt BMW made them too aggressive almost intentionally on the f8x just to give you that racecar feel. But now with the GTS flash it's smooth and puts the power down without hurting your insides.
And now the transmission seems to manage power delivery much better after adding JB4, intakes, charge pipes, downpipes, and full Akrapovic Evo exhaust. Part throttle shifts don't unsettle the chassis and WOT shifts are faster than I've ever experienced.
Would I flash the DCT software again? Yes, absolutely. The changes in casual driving are worth it alone, but the changes in aggressive driving solidify it's worth.

+1. This is a must! Its night and day.

Appreciate the feedback, glad you're happy with the new setup.

Tell me, where's the difference in parts from the transmission downstream through the power train? Wheels and tires excluded of course. ;-)

I think I already have Euro DCT but I'm interested in the GTS how can I tell witch one? What are the differences?

add another to that list. Thanks as always!

[exia_m3]

I have it on my 17 ZCP F80 through bootmod3 comes with the flash

[skalberti]

Does this flash affect anything on the warranty? The FDL coding doesn't affect the warranty, FDL coding is not the same as flashing.

[Irishace]

Mandatory mod for all DCT owners. Have it through BM3 and it is night and day over stock TCU tune. It's so much more responsive and the shifts just snap.
