WWKD?
Having thought about it seven ways from Heck, for a long time now, I would open it up much like the current ignition system rules - with a couple of constraints or choke points on the system:
"For cars so equipped, engine and drivetrain management system hardware and software may be freely modified or replaced, as long as manifolds, throttle bodies, fuel injectors, fuel lines, and any other device which acts to physically limit the amount of air or fuel entering the engine remain as delivered."
This reflects the "it's just an air pump" mode of thinking. I'd set free any hope of controlling or limiting functions within this framework (e.g., traction control).

I like this approach, however I think maybe we should just allow the stock throttlebody diameter and configuration be the limiting factor. Set the Cis meters and Digfant style flapper boxes free in favor of modern air flow meters or mass density set-ups. This would help the older inefficient cars get up to par with the modern fuel delivery systems. Do we specify that injectors must remain stock as well? That would force the mechanical guys to use that old mechanical meter, while allowing the motronic/flapper box people to remove it.
