Yes, I bet using a wideband with enough computing power could solve a lot of the issues, especially if the system could self learn.
I just don't want to be the one who has to figure it out :-)
It's actually not that much computing power really. Remember the original was solid state, and didn't really do anything that sophisticated (if volume of air is X, and temperature is Y, then put in Z fuel) (ok, it did a little more than that, but not much!). The megasquirt does a pretty good job of constantly reading the mixture coming out the engine, along with the other sensors and dynamically changes the fueling many times a second.

Re: IDF ITB vacuum

Both of these were on V8 carb--ITB conversions.

One man made little plates to go betwee their IDF style Throttle Bodies and their intake manifold. Each plate has two ports. They ran vacuum lines from each port together, and then into one MAP sensor.

Another fellow tapped into all 8 manifolds, ran the lines to a small egg shaped "manifold" , and then into a MAP sensor. He said that he could have used just 4, but didn't realize that until he had built out the system.
