Nope.  MS-II.  Version 3 board.

Here is a mass air flow sensor I picked up in a junk yard for $50.
Ford Escort. Do you have one yet?

I also have a stock Mazda 2nd gen turbo version trap door type but it probably
has more pressure drop than the Escort.

No.  I don't have one.  You're not planning on putting that thing on an
airplane, are you?  A MAF sensor is not needed or desired.


Maybe not with the Megasquirt however 99.999999% of the rest of the
gasoline engines in the world use them. The Megasquirt uses a throttle position
sensor and intake manifold pressure. Perry Mick has 800 hours or so on his
stock Mazda trap door mass air flow sensor. Works great.
