Yup just gonna avoid WOT while I drive it to work and back during the week and replace all plugs and coils at the weekend, then hopefully I can just enjoy the thing misfire free for the next couple of years
I’m not overly fussed about the dsg fart really, just would have been a cool added bonus.
Here's an overview of the Z4 functions, and which one to use:
There are five drive options...
Normal (Select this one)
Sport
Sport+
Traction
DSC=off
...And three DCT options
DCT D
DCT S (Select this one)
DCT M
Then use half throttle in lower gears - get it just right with decatted exhaust - BANG! on gear shift.
Has been there across any tune that I have used as far as I remember. It might also be there in other mode combinations. Haven't tested.
I've noticed the same kind of bang on upshifts under certain conditions but I've never used an MHD OTS map.
I normally attribute it to retarded timing due to boost overshooting target before the shift. That'll happen at certain rev ranges more than others depending on how the PID is configured.

btw, did some logging tonight, and it seems no matter what button I push, "sport mode" for transmission does not change to active. So this sport mode might related to other versions of the DCT software.

Did you try knocking the gear lever to the left? That is referred to as a sport mode in the manual so might be it.
That is weird. I wonder if it’s just that the PID on deep OBD isn’t mapped correctly or mapped for a different vehicle?
Flashed v9.0 with a short run but didn't note any extra upshift noise.
Mine 2009 N54 335i DCT zsub 8609092
Initial impressions are good compared to 8.1 I haven't got any overboost codes but maybe too early to tell.
I know Ronald has a 335is so maybe that's the difference

Love to take the credit but that’s not mine it’s a screen shot from the vid
For DCT guys, do you tick linear throttle mapping? I recall someone mentioned that xhp advised against for the autobox but haven't read anything against on the DCT. It's much easier to control with it ticked but I don't want to be doing anything which will harm it in the long run.

Dropped the new coils in this morning, went for a long drive tonight and did a few 2nd/3rd gear pulls. No more misfires and car pulls hard with v9 S1. Unfortunately I don't have anything to compare it to since this is the first tune I have run but it felt smooth and power delivery is spot on, no complaints. Going from memory here but I don't believe I ticked linear throttle mapping FYI.
