See below on your .11 correction assumption..

I have read somewhere that the injected fuel is not measured but ........

calculated based on the measured MAF air flow rate and the stoichiometry. I'll have to search to find it. When I do I'll post it.
But if this is the case, then the MAF does directly control the calculation and the 1.11 factor applies. IF not then it is more muddled.

You've changed the fuel delivery rate though...>

with a 4 bar and the computer knows nothing about this little juggling act...

The fuel is definitely measured by the injector rate Using the known 386cc delivery rate (at 3 bar). The 4 bar alters this by +25% though..

Only the down stream readings by the 02 catch it.

So...Less air being recorded by the MAF, but more fuel actually being delivered by the 4 bar....With the 02 balancing it all out, the net effect is probably marginal (since the STF's and LTF's come in within a few %) I think the .11 you're assuming is not realistic in the overall calculation..
