Perhaps.  I haven't yet made up my mind.
The concept is simple.  The devil is in the details.  If I can buy a module
ready made that takes TP, MAF, and RPM (no lambda, no crank synchro), and I
can get inside of it to fiddle, that's where I would probably go.

I have a shaft driven positive displacement mechanical pump capable of much
more volume than I require.  I assume the Hilborn has a pump capacity that
matches the desired fuel delivery rate.  Putting a regulator on such a pump
would throw the more rpm=more flow out the door, right?
