Is there any need to increase the line pressures with adding more clutchpacks? Seems common in the f8x world, but not much info on high-torque n54 dct cars.


I haven't had any issue with mine. Just switched to SSP clutchpack and no issue since then. 1 year since!!

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.
This is incorrect. You can flash m3 and m3 GTS TCU files from the e9x family but not the f80. Also the M3 TCU flash does not change the rev limit in your DME If thats what youre saying or are you saying that it will allow shifts up to 7500?

The 35is flash is awesome. Should have done that 10 years ago.

Which version were you running before?
Which are you running now?
And most important.. What changed?

I am on 8606092 since i have the car. Never tried any other revision.

Here's a guide by one of the stars of spoolstreet: https://bmw.spoolstreet.com/threads/recommended-android-apps-for-e89-owners.6076/post-90902

Gotta admit I forgot to note down what version I was running before (2009 EUR Z4 35i).

What changed? Well my biggest problem with the old DCT flash was the D-mode. Because I'm running the S55 flywheel, I get chatter when loading the drivetrain at low rpms in high gears. In D-mode that happens all the time, because 7th is selected as early as possible. This means I have gotten used to drive around in S-mode.

With the 35is tune it seems this problem has been reduced, meaning the shifting points must be higher in higher gears. I now use D mode all the time, and have yet to hear the flywheel chatter.

Shifting speeds have also increased and feel both smoother and more precise. This means the driving character of the car is less laid back in D mode, and sportier in M mode (DSC=off). S mode also feels less "sequential" if that makes sense. Overall the car feels lighter on its feet, and more adjusted to the higher power.

So interesting information which you probably already know.
I flashed my friends 135i DCT with the Z4 35is 8647893 ZSUB.
works perfectly and he said it feels amazing. However the LC didn’t work.

a while back I loaded the 8606092 335i DCT flash on my ‘09 E92 335i DCT and also my mates Z4 35i.
my LC wasnt working before the Flash. And then it was working after.
my friends Z4 35i LC was working before the flash, but wasn’t working after.

I’ve just realized that this is because the Z4 35i and the 1/3 series cars have different ways of accessing the LC sequence.
1/3 Series have the DTC button
Z4 have the toggle to switch to Sport+.

because of this little difference, the LC won’t work if loaded for the incorrect car. But everything else will be perfect.
This was tested when I put my mates 135i onto 8606092 after the Z4 35is 8647893 flash. His LC was back and operating perfectly.
Thought I’d share.

I’ll be loading the Z4 35is8647893 flash to my mates Z4 35i over the weekend now.

Hey guys is this something that can be done through Team Viewer? I would love to have the 35is flash or whatever is the best, but I'm clueless with how to flash the DCT or what software to even use.

This is the DME or engine management part. If you want to flash your DCT have a look at the various threads in the DSG section around XHP flasher

Hi guys,

i loaded the 8606072, which is from the 135is, on to my 335i E92 N55 RHD. LC works perfectly well, it shifts ok too, but I think not as smooth as the previous software, or it might just be my impression, I don’t know... There are no codes whatsoever. My question is, should I load the 8606092 version instead? In the chart posted on this thread, this version was loaded on N54 engines, I don’t know if that would make any difference if loaded on N55 engines. Thanks in advance.
