Anybody have cfm vs maf volts data for Z32 maf?
If this data is available, I sure would like to see it.

Hmmm. Good point.
I guess what I really am looking for is mass flowrate vs maf voltage.

wouldn't that be mildly different for every car? well I mean generally for one specific engine it will look the same...

400 lbs/min at 3.5V
600 lbs/min at 5.1V (max capacity)
Whether or not these are accurate numbers will have to be verified, if I can find other data. I'll update as I find new data.

yeah I couldn't tell for sure if they were just using those as actual data collected or if they were just using them as a random example... partly because I'm too lazy to read it all. Hope that helped though.

I don't think the Z32 maf is good for that much. Maybe the numbers are cfm, which would make more sense (and actually corresponds well with power vs maf voltage I've been seeing), but then that begs Mike's question of what pressure?

yeah 45lb/min doesn't sound too outrageous (600CFM->lb/min)...
