OK, first thing you should know:

MAF (mass air flow)/AFM (air flow meter) sensors are bad.

MAP (manifold absolute pressure) sensors are good.

Converting to a MAF/AFM is a step in the wrong direction. They aren't as presise as a speed/density fuel system (like comes stock on Hondas) and choke the intake tract with a flapper door or screen, depending on the model used.

This is coming from an RX-7 guy stuck with a factory flapper-type AFM. FC owners, DSM owners, and lots of other car guys fight to convert to speed/density systems because they have better power potential on all setups. Honda owners don't realize how good they have it right off the showroom floor.

If you absolutely must have a MAF, you have to buy an aftermarket EMS (Haltech, Microtech, Wolf, etc) on the order of $1000+. They can be configured to use MAF sensors.
