Honda map sensors are 1.75 bar, which equates to ~10.5 psi or so.
The most popular map sensors are the GM 3 bar, AEM 3.5 and 5 bar and for hondas, the Omni 3/4 bar sensors.
When choosing a map sensor for your car you just make sure that the max amount of boost pressure you want to run is less than the max amount of pressure that your map sensor can handle.
So choosing a 3 bar map sensor will allow for 2 bar of boost pressure (you have to subtract atmospheric pressure, which is 1 bar), this first 1 bar of pressure would be the vacuum portion of the map.
So knowing that, you can figure out the max boost pressure of a GM 3 bar map sensor to be
(2 bar * 14.5 psi) = ~29psi
**(1 bar = 14.5 psi)**
Which is MORE than what most people are going to run.
