motec 3 bar map specs?

[bseriesking]

anyone know the kpa readings at 1v and at 4v for 3 bar motec map sensors?? Trying to set up a prologger to read boost but it needs the specs of whatever map you are trying to use! It can be at sea level or whatever level of elevation, I'll figure out the rest. thanx

..for example, gm 3 bar reads 62kpa at 1v and about 262kpa at 4v.
