I understand what you are saying, the airflow calc uses a map value
and rpm terms. What throws me on this one is the mix of bpw and afr,
along with the cylinders mask! I've mod'd a bin to output the value
via the aldl.

A quick look at it shows that it appears to be mostly a load value
and engine speed term. It is interesting that by using the afr in the
calc, the richer the engine is, the final value is reduced in magnitude.
