I have asked this question before - I was going to try using a new-style
"high flow" MAF (they are frequency type). But, as with ALOT of other
projects, I have  put it on the back burner. If you find out about using a
frequency-type in an analog setup, PLEASE let me know. I suspect that all
you have to do is change the bit at 014, but very seldom is anything that
simple......Good Luck
