The GTS flash is M3 based DCT software. If you're willing to install a M3 GWS with all the prerequisite parts and change your final drive ratio to somewhere close to the M3 DCT ratio of 3.15 you can use it.What method do you use , and i saw that people were doing a GTS tune changing the shift time time from 120 ms to 90 ms

@LMB335is is correct. what i was trying to say is, there is no "custom" DCT tuning, like you find on the 6AT and 8AT via XHP. people are just flashing OEM files with OEM tools right now on the DCT. I was speaking about tuning your DME.The GTS flash is M3 based DCT software.

I am confused about this ZSUB; is this different than the US 335is setup? I understand DCT was offered in other countries but I wasn't able to find much information on that ZSUB; it is the "German" DCT setup?Agreed and going to say again that the DCT offers no custom tuning,
I have a 2009 N54 DCT E92, and since i owned the car, my LC didnt work, and shifts were tame,
i since researched and recently used WinKFP to load ZSUB 8609092 DCT flash, and the shifts are now alot more aggressive, and alot faster.
I also have my LC back and it works as required.
If anything, i would recommend the 8609092 ZSUB flash.
So you had the chance to compare both versions in your car? I actually cant imagine any harder shifts So i am very interested in your summary.My humble opinion. The best non M flash for the DCT is actually the z4is. Basically a 1M engine with DCT. Everything else isnt as sharp until you into the M stuff like LMB335is. But then you need to consider final drive changes.
I am happy with my ZSUB and don´t see a reason to change. I just thought to ask about your personal opinion but it seems you haven´t compared them yourself.Its not just about how hard it shifts (for me) and the feeling it gives is affected by many things and so comparing one with another can lead to the wrong conclusion.
From a logical perspective the highest horsepower N54 DCT car from the factory was the z4is.
It was also the quickest 0-400 (do a search of threads where stock cars went to the track)
My suggestion is that you do your own comparison for your own car.
Every car is different as is every owner. I tried 135is , 335is ended up going back to stock then 135is again.I am happy with my ZSUB and don´t see a reason to change. I just thought to ask about your personal opinion but it seems you haven´t compared them yourself.
What do you want to achieve exactly?I want to flash my 335i non IS DCT soon so want to make sure I get the best one.
I have been told that the only way is upgrading to M3 cluster and all other stuff needed ( there is a thread about this). Then you are able to flash the modern m3-m4 gts trans flash so this way you will have 7,500 rpm rev limit.Any ability to increase shift limit beyond 7k for 335is DCT?
