MAP vs MAF

[gil_ong81]

Can someone please explain to me what the difference between them?

MAP reads the air pressure in the intake manifold and MAF actually reads how much oxygen is in the air.

MAP takes the pressure and calculated via previously determined maps that Xpsi has X oxygen in it.

make sense?

BD/BG's had MAF sensors. Its the thing with the electrical plugin right after your filter.
