What is my volumetric efficiency?

2.2L OHV (not ecotec).

what an unusal question to ask, attached is a link explain things in more detail,

That doesn't help me, because my Sunfire does not have a PID for MAF.. IOW, I can't get the MAF data.

Thanks, though.

Any other ideas?

well it's an economy car not designed with volumetric efficiency in mind so unless you want to have it tested or can get the info from GM I doubt anybody has spent the time and money to do it. Best guesstimate the 80% figure.
