Hi Guys, i have question about mass air flow data in cars without MAF sensor (for example mondeo mk3 2.0 TDCI 115HP- this car have only MAP Sensor).
How ECU know what is actual MAF in this car (MAF is part of smoke map)?
Airflow is calculated from pressure and what (time)?
Sorry for my English.

map = pressure / rpm
maf= air flow / rpm
