I think any table that is modified by the OE is useful in the XDF. This table was modified on cars with DCT transmissions to taper boost target and prevent closures on shifts so probably not much use for MT users since they lose all boost during shift anyway.

There's a mountain of useful tables that could still be added so I'm interested to see what's coming. I expect the burble tables will be included like fuel cut delay in normal/sport, fuel cut delay while static and also the timing reduction during overrun. Again, these tables are modified by BMW depending on the application of the N54 so if you're a 335i driver that wants Z4 style burbles/bangs then it's very useful.

Another one that would be useful to add is the accelerated pass tables. It was a noise control function built in to close the exhaust flap during acceleration. Currently even if you set all the exhaust flap tables to open the flap will still close momentarily if you accelerate. I only defined the gear threshold for it so I can turn it off (make it only operate in 8th gear) but there's a group of tables that alter when the function activates depending on pedal and gear. It makes quite a difference to the exhaust sound if you still run with exhaust flap active.

All the variant toggles are useful too. cruise, trans type, DMTL, US/EU spec, hydraulic/EPS, vehicle power class.

@carabuser Do you know if in these tables there is also the possibility to have the flap close only in P and N on a DCT? I set it open everywhere except in gear 0 but when simply stoping at a traffic light the flap would close.

I can't remember the logic priority exactly but the flap should almost always be open while at a stop. The highest priority is cold start where the flap is forced shut but after that it looks at the static position which is set to open at speeds below 17kmh. Only after the vehicles moves does it look at the torque request lookup table of gears and rpm.
