OEM AFM - Voltage vs. Air Flow Data

OEM AFM - Voltage vs. Air Flow Data - ALSO POSTED IN GENERAL TECH
Hey Guys,

I know this has been talked about numerous times, lots of promises, hopes, dreams, blah blah blah.....

Like it says, looking for the Voltage vs. Air flow table(s) for the Bosch AFM's. Sent Bosch an email the other day, no word yet, probably never will hear from them. Anyway... armed with this data, we could build a inexpensive MAF conversion for the E30. Was thinking straight swap, no piggy back, external electronics or any of that jazz.

And yes, I have searched for several days now. No consistent data as of yet. Please, don't say hook it up to a flow rig and reverse engineer it.

Any information would be awesome,

Still Air flow and Air mass flow isn´t the same thing,

Obviously the most sensable thing would be to bolt a maf infront of a AFM and datalogg both unit´s voltage.

Thanks...

By referencing a volumetric flow to a standard temperature and pressure, an exact mass flow (g/min) can be calculated from volumetric flow.
It is common in the industry to specify mass flow in terms of volumetric flow at standard (reference) conditions.

Obviously, the most sensible thing would be to connect the AFM to a accurate calibration rig and determine it's output that way.
