Can the MAF be tuned without driving??

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.

Typically it does not need to be altered. Hence why I run MAF only and dial in the VE tables by data logging the VEs on a running engine. I can get the VE tables very close using MAF data and a histogram.

Is there a "how to" posted on this method somewhere? That sounds interesting.

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.

So, what's the highest Hz you can reach in neutral without the engine experiencing rapid unscheduled disassembly?
