Its done on a flow bench with the representative intake plumbing. Virtually every sensor or actuator is characterized independent of the vehicle.

That is what I thought. Care to elaborate why when it is unmodified on that stock vehicle/location that it needs to be recalibrated? Or does it? Most seem to think it does. I'm sure the OEMs go through a lot of effort to characterize it. I'm asking because i know you were an OEM calibrator.
I suppose it depends on a few things...age of the vehicle, engine/hardware health, what you consider enough error to justify recalibration, etc.
Yes, I wrote a thread on it. It incorporates fueling correction, so if you wanted to strip that out and populate VE from MAF only, remove the fuel trim part of the parameter.
