Poolside, Thanks for all your work. I've followed along off and on and read the entire thread.
I have a basic understanding of what you're doing..though I still relate most of fuel mapping to carburetor terms and circuits.
I've spent my life in manufacturing and know what a PITA development can be.
But given the choice, I'll take development over production any day.
If it was me, since the development is complete, I'd turn the production over to someone else.
Take your cut and let the marketing and manufacturing guys set price points, determine production quality, advertising and their margins.
Of course I might offer a limited time buy to a few faithful that followed along in the early stages....
But that's just me.
