My 2002 Honda Accord V6 has a Manifold Absolute Pressure sensor (MAP). I understand that this sensor gives out information in pressure units (psi or equivalent). After doing a bit of research, I realized that my car does not have a Mass Air Flow sensor (MAF). Based on this document (page 4), I know how to calculate MPG from data retrieved from the MAF sensor (which my car doesn't have).
Is there any way for me to calculate MPG from my MAP sensor? Or is there a way to convert between data received from the MAP sensor to data that an MAF sensor would have reported if it existed? My end goal is to be able to calculate MPG using my MAP sensor (I'm using an OBD2 device to get all the data). Thanks!
