Can someone give me a rough guide as to how i can connect a MASS AIR FLOW to VEMS that it can get signal and reading from it?
preferably one with a hot film such as one from an RS4 (car is an audi I5) .
the idea is to see if the use of a MAF could make vems readings even more precise. If it is too difficult ill probably leave it be, but i was just wondering...
You can connect it to any of the analog channels.
what readings are you wanting more precise?
i wanted to compare how lamda is modified on cruise depending on airflow actually.
However i know that MAFs need to have some calibration depending on their size. how is that done?
They are fitted to a flow meter that can flow more then the HFM can measure as maximum.
then they are metered at as many data points as possible and a curve created.
Does this require special equipment to do? Or has anyone already done it?
