Njay, that's very helpful. Thanks for answering so promptly and clearly.

I wonder how prevalent that sort of system is, since it does seem to complicate the analysis.

And from an engineering perspective, I'm a little surprised that the system would be designed that way. It would seem to make more sense to tell the ECU what the intake pressure is, and let the ECU decide whether or not to let that information influence pulse width. In other words, if I were the designer I would address the issue by making the software a little more complicated, instead of making the hardware a little more complicated.

But maybe the system isn't very common, and maybe this is the reason.
