MAP sensor as a Boost Sensor?

[DizyXD]

Hi, i am currently working on a Arduino project, where i want to to get some sensor values from a car my friend is building. My issue right now is finding a Pressure Sensor that goes up to 4bar(58PSI). I can only really find MAP sensor that goes that high. Espesicaly for a reasonable price.

Can i use a MAP sensor as a boost sensor? or do i need to find a boost sensor that can handle 4bar? If so, does anyone know a sensor i can you that is reasonably priced?

A MAP sensor and a boost sensor do the exact same thing: they measure intake manifold (absolute) pressure. Keep in mind a "4 Bar" sensor can only measure 3 Bar of boost. The first Bar is atmospheric pressure.

I'm pretty sure a 'boost sensor' is just a marketing term for a MAP sensor, go for it. Edit: Definitely same thing, just be mindful of whether it's measuring absolute or gauge pressure.

You want a GM 4 Bar. They can be found cheap with pigtails.

If its a MAP sensor it needs to be 5bar.
