I don't know much about the topic but from my understanding even though the knock sensors are there for a reason and can compensate, wouldn't the engine prefer not to deal with that?

I've used several different cables and have seen no difference between a cheap INPA K+CAN K+DCAN off Amazon and something more expensive.

The FT 232 chipset is the standard
91 is premium here as well. Seems to me if BMW says to use 91 they did so for a reason. The manual doesn't say go ahead and use regular if you want, but you'll get better performance if you use premium. It says use premium.
