BPV frequency? Can't be logged. Do you mean N75 frequency?
N75 frequency definitely correlates to boost levels (assuming you are running factory boost control and not MBC/EBC). It IS the wastegate duty cycle.
Fuel injector ontime will vary with boost and tuning (i.e., how rich the chip is programmed to run).

he only time you will notice a difference is between shifts, or if the ecu needs to hit limp mode
my shifts are crisper now, as the BPV vac line now acts like a digital signal, on/off.
of course this is a little too digital for a 'luxury' car which is why audi added it.
remember AEB engines dont have one, the BPV is plumbed right to the manifold.
