I see your point - the ecu will define when an injector opens and for how long. But surely that does'nt actually measure the amount of fuel that has passed through. At best it would only be an assumption of what ought to have been used. I think there could be a big difference in the two. There are just to many variables for this to be accurate. In my experience the only accurate way to measure the volume of a gas or liquid passing a given point be it in or out is to use a flow meter (e.g. similar to whats used on the metering system on oil tanker delivering home heating oil ). As yet I've never seen a metering system fitted to a bog standard mass produced car. The only recommendation I would make is to buy a packet of salt and take a good pinch when reading what the computer reading says.
