I think you may have unrealistic expectations of IFC exchange. From what you write it seems to me that you expect that an MEP element is exported from Archicad and its should be imported into Revit as the same MEP element types, with all its parameters transferred and working properly.
This is unfortunately not a realistic scenario.
Geometry transferred from one BIM application to another using IFC is mostly recommended to be used as reference geometry based on which users can model their own geometries in their own software. BIM software are so different internally, one from another, that it is practically impossible to transfer the same parametric behavior between them, this is why IFC exchange is mostly for reference geometry.

I'm talking specifically about duct, pipe and cable trays which are system family with proper clear definition. I'm not talking about special Archicad/Revit properties. i expect from the global properties (length, diameter, width, height) to be shared in a way that would be easy to translate them on another BIM software.
(anyway, maybe its only my BIM utopic vision)
for example, i found a specific setting to export walls and floor the be a regular element family.
