Factory sensor voltage to value charts?

As the title suggests, does anyone have charts for the sensor ranges and matching output voltages for things like the MAP and oil pressure sensors? I can't believe it's this hard to find that info, but I'm not having much luck so far. I was hoping I could pull it off of a datasheet from someone like NTK or AC Delco or whoever makes ones that fit, but they only seem to mention vehicles that they fit on their websites if I can even find the sensors to begin with. Looking for values like 0V - X psi, 5V - Y psi kind of numbers. I'm going back through my setup on my Megasquirt and wanting to get them as correct as I can just for the sake of argument. They are mostly just there for extra info right now as they aren't critical to the car running, but I'd like them to be accurate if I'm going to have them. I tried watching the raw readouts while applying vacuum and pressure to the sensors, but the MAP sensor especially never made any sense to me the values I was getting. The oil pressure sensor I think I might have close with 0.5-4.5V readings of 0 psi and ~110 psi respectively, though I think the 4.5V reading seems a bit off. I'm thinking it should probably be 100 psi for 4.5V. Most 5V sensors values are given at 0.5V and 4.5V respectively, and most pressure sensors I've seen coming in 50 psi ranges, so I would expect it to have been 100 or 150 psi, maybe 120 as a bit of an oddball, but I haven't even found a maximum rating for the sensor anywhere. The MAP sensor should be pretty straightforward as well and I would assume would be similar with something like 0.5V being 0 psia and 4.5V being something like 14.7 psia (or 1 bar or 101.3 kpa or whatever unit you want), but it doesn't seem to agree with the MAP sensor built into my Megasquirt when I set it up that way, which is what got me going on trying to find the real specs to start with.
