Yep.

Most cars can give you an actual load as a percentage of power, its LOD on the SG, dunno about the UG.

It depends on the ECU programming. Some engines give you actual engine load as a percentage of power currently available. Some report the load of the engine versus maximum power output. I think most are the former.
