That's it. It might be the values your rom uses in tables more than the calc method if neither makes a diff.
That's the one. 2 might be really old, no idea.
Yeah I'm starting to run out of ideas. @corbanistan was kind enough to send me his bin file and I forced mhd to do a full flash, but still nothing..
I had a look in the difference table, and we had different software revisions. He is on I8A0SIFK3 and i'm on I8A0SITA3. Theres a ton of bytes that are different between the two. (stock for stock)
I'll record a log tonight or tomorrow of cruising and shifting thru a few gears, and maybe some shifts at WOT. Maybe we'll be able to infer something from that
Also been wondering if it's something with my car, like an exhaust leak etc etc. I'll get the car on my lift tomorrow morning and have a look as well.
But I swear once I set Reduction by Ign to 00 and enabled PU safety I got the shift burbles and tables enabled

I was browsing the base maps from other cars and found that the burble timing tables are defined on the B58 Maps.
INA0S Stock: B58 Stock:
the rows have very different row units so not sure which row is comparable with which. But wht one can see overall is that the B58 has way higher negative timings for burble than the N54. Especially in the high rpm ranges. Might be cat killing potential but also it should change the burble character i guess.

Interesting, I've not looked at the B58 maps before.
Is the unit scaling on the rows the same? They are scaled in mg/stk in the N54, I would expect the same in the B58.
The reason the MHD burbles on the N54 have no character is because they are badly implemented. If you use a custom tune you can use these tables and the burbles sound good. If you use the MHD slider then you just get harsh sounding bangs and the car will become jerky when going off pedal.
I downloaded the XDF and BIN for B58 and it does look like it uses load rather than air mass. They are essentially the same measurement so it's not a meaningful difference.
You can calculate mg/stk from maf. So if you log maf in MHD you can convert using this calc: https://instacalc.com/55271
I just did that from memory so not 100% certain but it looks correct from running a couple of test values through.
The character of the burble comes from the way the timing is ramped down in overrun, this table creates a nice gradual (as in over 100ms) reduction of timing that prevents the jerk that you get with MHD and creates those gurgle noises rather than any sharp bangs.
Yep what carabuser said, don't use MHD burble slider if you want nice sound. I was able to get my tune to do it the right way and it's great. No gunshots. Almost like what you'd hear from a high-end sports car from factory. Make sure Tq Reduction by Ign is set to 0. And I get nice burbles from gearshifts (MT) too now.
I checked also the IKM0S table and it is very different from INA0S. May be it was already posted here but then i just overlooked it.
So this is IKM0S
B58 (as posted above)
So looks to me as IKM0S is targeting a different burble sound than INA0S.
I took that as my base table values and adjusted them in the first three rows a little.
Also i orientated by the B58 pattern so that between two values on is not suddenly lower than the right and left neighbour.
Just like the 1600rpm Column.
Weather is great today and i will go for a small test.
Careful with defining your own tables for that one. There is 3 tables with similar structure that are used under different circumstances and they are adjacent in the bin.
One is ignition angle in PU mode (overrun), one is EXT (dsc, msr etc) and the other is normal I think. It looks like you have the EXT table there.
So went out for a little drive but couldn´t get far because of never before seen traffic in all directions.
So there was some sort of burble but really not loud, barely noticable. On MHD i was on soft and it was well noticable.
What i noticed in the log is that the car goes to max -8 degree of timing. I have that value in no timing table
Based on the ignition table above between 1600 and 2400 rpm it should be minimum -16 degrees
I have set Disable TQ Reduction by Ign to 00 (INA0S)

It's not a timing target exactly, it's a minimum that can be applied by the torque target routine.So went out for a little drive but couldn´t get far because of never before seen traffic in all directions.

I think there's other offsets applied. You can try lowering it even more and see if it drops further than -8.
If the timing doesn't drop further then the actual torque is probably at or lower than requested torque.
You can try modifying a stock bin and see if that works in the desired manner. That will rule out a problem with the BIN you are using as my burbles get pretty nasty when i lower that table even by 3 degrees.

Thanks to @carabuser! Some of my torque reporting tables were setup by the well known spreadsheet but actually seem to have had impressive influence on my DCT behaviour either.
Not only is the burble where i expected it but also the dct now acts completely different. It was great before already but now... different level.
