Volumetric efficiency is a direct multiplier upon calculated air mass, so a 10% change in VE yields a 10% change in calculated air mass. Collecting the data to populate the VE table is a tedious process. When working with a complete engine and wideband to solve for VE, there are several serious concerns, first, one must understand that there is a very strong assumption of accuracy in fuel delivery.
When adjusting VE based on measured lambda error, we are basically saying that all of the delivered error in air/fuel ratio is a result of improper air mass estimation. In doing so, we rely upon the fuel injector to act as a metering device.
