Sorry, I misunderstood your previous post. I have the limiters all tweaked!

I completely understand Kory. How does the ECM know how much fuel we're flowing..hmmm...maybe a calculation? (rhetorical question). Now that being said, how does the ECM know duration...injector opening time! Hard facts is how it knows. Thanks Kory.

Guys, correct me if I'm wrong...but in my logging experience... no matter if im commanding 300mm3, or 200mm3, you are only going to get 145mm3....in some cases you maye get higher 150+mm3 ect..but the max fuel we are asking for is at the bottom right of our Main Injection table... You can demand more, and i do in some of the tables but honestly just for making the tables nice :-)...but i want the new guys to understand, just because you put more than 145mm3 in your limiters does not mean you will get more fuel. Full fueling is at 145, anything above that is making the tables pretty in my experience...

That is accurate with stock injectors. If you have larger nozzles, then the actual maximum volume can be higher than commanded. What is important, though, is that the commanded volume is a reference.
Ultimately, I think it may prove to provide some benefit if one was able to accurately modify the volume axis for the exact injectors being used. This would require a flow sheet of the injectors with multiple pressure and volume points.
