Do you have a log file when this happens so we can help ?
30 kpa is most of the times decel

i had r8 coils, now i have b58 coils without amp inside, as in result looks like emi affecting knock sensor signal because i have them without shielding.
Only knock sensor wires should be shielded. When you changed coils probably there is a problem with the ground.
The passive coils draw current directly from EMU using power grounds.
For me looks like grounds problem
maybe you know better, those coils has 3pins (plus, minus, trigger)
But they work only as Coils without amplifier and CDI pulse, spark at falling
how to tell what is correct setting?
they come in bmw b58b30 (12138643360)
controlled by FGD3040 in oem ecu
You cannot use CDI pulse ! Your spark is in wrong place for sure.
For such coils you need control it as a passive coils.
