I know you're exaclty right about how "nice" it would be to use a multi-bar map sensro. Wyatt and I talked ourselves about how nice that would be, but it goes back to the same problem that you were initially trying to solve. A CPU that would agree with the upgraded tuneable map sensor. Our current cpu would go bonkers over seeing a map sensors that isn't the spec one.
However, with a better one, liek you said, that would give us that much more flexibility for tuning for a better, more leaner formula under boost that's above the 4.7 volts. Right now at low boost, the boost-dependent FPR is a pretty nice alternative, but it would be nothing compared to electronic tuneablility.
