have both , and DSO and 3 diff full logging, OBD2 Scan tools. ( 96 era to present)
the MPGuino, is the cheapest path to the answers.
the Sensor way , is not any good for the reasons stated.
it is a calculated value and not a sensed value.
A derived result that only comes close when cruising. (and then only after a careful calibration of the tool)
the MAF in no way senses gas flow.
