what is it, where does it go, where can i get one and how do i put it in :-) hehe thanks in advance

 

If you can't answer those questions yourself, you probably don't need one.

Manifold pressure sensor, it gets wired in to your ems and connects to a vacuum/pressure source from the engine. Dont have part number, but any auto parts store should carry them they are a stock GM part.

 

if i dont know what it is then i dont need it? what kinda logic is that...do you know about every function that you brain carries out? yet you still need it.....

 

A 3bar MAP is an aftermarket part used by the ECU to read manifold pressure that a stock MAP cannot, generally on turbo applications where the pressure inside the intake tract is a lot higher than on a NA vehicle. You don't need one unless you're runing a high boost turbo app.

 

you dont need it unless you're running 12+psi of boost

I thought 10psi was the most the stock MAP would read?? I dunno you're probably right, I had the number 10 in my head though

i think it's good up to ~12psi

 

The stock map sensor will read manifold pressure up to 11psi, but any more than that requires an aftermarket MAP sensor

 

correct, you CAN run 11psi on a stock map sensor, but thats it!

 

well mine only made it to about 10.....so where can i get a "gm 3 bar sensor" also is there a specific type i need to get for my gsr motor or are they all the same?

 

GM is a manufacturer of the 3 bar map sensor...
so theres 1 kind, not one thats specifically for your integra.
There are a number of sponsors on our forums that sell them for 70 bucks and up, and you can find a howto on how to install it on this forum.

 

now if i install it will it throw off my tune? My car is dyno tuned to 10psi with hondata s300...i need to get the boost up to start making some real power but can i put the map sensor on and drive it or will it throw everything off?

 

you'll have to set up the hondata for the 3bar (being that you're replacing a honda part with a GM part).

 

any hondata tuner should be able to install the gm 3bar, its also on the hondata website. goto any gm dealer and look up the part # then go online and buy it from a discount gm parts dealer. i purchased mine around 50 i think on ebay years ago.

its for runnin any boost over 11.5 psi or around there since the stock map cant read over that.

 

im lookin for a 3 bar map sensor for my 1999 civic si turbo. is there a paticular one i need, or will any map sensor for all civics integras? anyone got one for sale because who wants to run at 10 psi haha, thanks guys????

 

Go to a local auto parts store like autozone or somewhere, and ask for a GM 3 bar map sensor.

 

Stock Honda maps can read up to around 11psi (I think its 10.3 or so). If you go higher than what the stock MAP sensor can acknowledge, the ECU will only know to put as much fuel as it should at 11psi. So understandably, you'll progressively lean out by pushing higher manifold pressures.

As for a 3 bar, It can read up to 28psi, which is great and all for higher boost applications but as an alternative to the 3bar Id suggest looking into a Motorola 2.5bar map sensor. Theyre cheaper and 3-Bar map sensors are not able to read vacuum levels lower -18in/hg.

Whatever you choose to do; Heres an tech articale for the 3bar

anyone else recommend motorola??? or should i stick with the gm one?

 

I'm using GM and it works good for me.

How much psi do you plan on running?

I bought an SVE 3 BAR map sensor from (I think) lightningmotorsports.com. Someone please correct that website because I forgot it. I haven't had a chance to put it on because I had to return my car to stock for CA ref.

You take off your stock map sensor and then find a way to mount the aftermarket one (it is bigger and has different mounting holes).

You splice the wires into the stock wiring harness for the map sensor (diagram found on link I previously posted.) Leave the stock map sensor where it is, and connect a new vacuum line to the new map sensor.

 

Hey guys sorry to bring this thread back but im planning on upping the boost to 10 psi. Should i go ahead and buy a 2.5 or 3 bar map or should i stick with the stock one since it can read to 11 psi. Im on a budget so if i can save money without buying a map sensor because the stock one will do that would be great! thanks guys!

 

Stick with the stock MAP sensor if you're planning to only boost 10psi (save some money). The only question is how long will you stay boosted at only 10psi?

 

If you have the money i would go ahead and get a GM 3 bar, 10 psi will soon turn into 15 psi.
