MAF transfer curves

[Rodney_L_Wiggins at keybank.com]

Different transfer curves for MAFs?
Is this true?? I was led to believe that voltage output was linear
with respect to airflow for all makes. The only difference being
the sizes and connectors used. I don't mean to question Chris but
This would have some serious implications for my flapper-conversion
project so I'm very curious.
Thanks,
Rod
