Depends on what kind of "self learning" system we are talking about.
With some of these new, self learning
throttle body injection systems... I agree- They are buggy (I think TBI sucks in general for performance applications, to be honest- If you want to run a cheap carburetor style intake manifold, then you might as well just run a carb on top of it...
)
But MAF/MAP combination port injection systems are fairly well established, and still offer the most EFI benefits for the cost (JMHO).
Olddog- Great post about wide band versus narrow band tuning - agree that it is all more about marketting BS than actual performance.
Your idea about integrating the MAFS into the 8-stack horns is one I have thought of as well - But I was thinking that the best way to do it would be to string an air flow meter across each air horn, and then program a chip to aggregate the signals from the 8 sensors and blend them into one air flow curve to feed the PCM, as opposed to using the signal from just one throttle body and then assuming that the other 7 are flowing the same amount of air... probably 6 of one, half dozen of the other- Your way would be easier (and cheaper)
But like you said- it's pretty much just a brain exercise, and would only add more cost to these outrageous $10,000 systems, so unlikely to ever go anywhere.
And like you also said- every year, more and more guys are running these systems - Eventually, the single carb look is going to be the most exotic looking
