Need a straight up answer about the MAP sensor

[F22HB]

What can it do as far as sensing pressure? I've searched a bit and I can't find a real answer. I've heard 1 bar, 10psi, not at all. idk, I just need a quick answer.

The stock map sensor reads up to around 11psi.

1bar=14.5psi

cool, thank you.

for most if not all turbo setups running around 10psi, i think a 2.5 bar sensor would be recommended. Any boost creep or boost spikes could be devastating, but properly fueled with the proper map sensor.

The 2.5 motorollas are quite cheap anyways.
I've got an extra lying around if you're intersted for $20 shipped. Let me know.

how do those wire in? can you just take out the one in the black box and put in the one ur selling and solder it in or how does it work? Thanks.

You'll need to find the diagram, commonly found on Honda-Tech or Google it, and then solder the wires to the pins on the map sensor.

I dont know if you can use that map with an afc.

hondata has a website that shows what to do. Also i think GM makes the 2.5 bar sensor for like early fuel injection models

Yep you would need a 2bar and up sensor to run boost properly. 2 bar would allow you to run 14.5 lbs, 3 bar would allow you 29 or so lbs of boost and so on.

GM makes a 3 bar sensor. You can buy from dealer or on ebay. They are hard to come by in yards so yea. They cost around 65 ish as i recall. They might have a 2.5 bar. I forgot what they used in the Grand National. The 3 Bar was used in a turbocharged firebird or something like that back in the day.
