MAT / TPS ignition retard should be MAP based, or configurable ( MAP or TPS )
Agreed, working on it (more work in VemsTune than in firmware).
TPS makes sense for engines that might not have MAP sensor at all. (ITB normally aspirated).
MAP is usually better and easier to tune.
So choosable is best.
Input for Coolant temp and air temp can be selected from non pullup analog inputs
This allows parallel installations to be done more easily.
