I'm missing something...

Not sure how this one works, but if I read / remember correctly, the CIS
air plate sensors are referred to as "mass air sensors".  I believe that
they correctly compensate for temperature based density changes.

As far as altitude based oxygen density changes, one question comes to
mind:  

Does the percentage of oxygen in the air (by mass) stay the same as
altitude changes?  If not then mas air flow isnt enough to predict oxygen
mass.

Just a thought.
