Evoscan Mass Air Flow value

[Davezj]

Hi all,
Does anyone know off hand if the value in evoscan for mass air flow value in grams/seconds gives a correct value?

I am trying yo work out the volumetric efficiency of my engine.
I have calculated the ideal mass air flow @ 100% volumetric efficiency based on engine and turbos and intercooler parameters but I need to need to measure the actual mass air flow to calculate the actual volumetric efficiency

I want log some power runs and be able to select rpm values from the logs and check the mass flow against the calculate mass flow for the given rpm.

I want to see if the volumetric efficiency is much different from my guesstimate of 85%.

Any help is welcome.
