what car uses 3 bar map sensors
 

what cars come stock with the GM 3 bar map sensors? i am a cheap ass and would rather pick one up from the junk yard than to spend $50+ dollars on one. any info is appretiated

Re: what car uses 3 bar map sensors
 

find the part # and ask the dealership to do a reverse look-up.

They are on GM HD trucks though.

Re: what car uses 3 bar map sensors
 

like the diesel trucks or just the big unleaded trucks?

Re: what car uses 3 bar map sensors
 

As far as know know the one you want only comes on:
Buick GN
and The Turbo TA Firebird

Good luck find any of those at the junkyard.

Re: what car uses 3 bar map sensors
 

the new supercharged cobalts come with them i am sure there are a couple totalled one in a j yard somewhere or go to chevy and order one

Re: what car uses 3 bar map sensors
 

im just too cheap to buy something new that i can get for super cheap or free. im sure they dont cost that much so if i cant find one i will just buy one

Re: what car uses 3 bar map sensors
 

Good to know. I have just heard something about them being on trucks. Never really looked into it b/c they are <$50 with a pigtail.

Re: what car uses 3 bar map sensors
 

what about 2 bar sensors? i dont plan to ever go over 20psi so i could get one from an eclipse or something right?

Re: what car uses 3 bar map sensors
 

2 bar is only good till 14.7psi or so.

It's 2bar MINUS Atmosphere, with is 1 bar.

Possibly 2.5bar.

Re: what car uses 3 bar map sensors
 

oh, i see. 2.5 bar would work then. i havent heard of those being on any cars stock, but maybe

Re: what car uses 3 bar map sensors
 

Can't think of any stokers running 2.5bar. Normally guy buy a Motorolla 2.5bar sensor.

Good till 22.5psi

Re: what car uses 3 bar map sensors
 

yea, thats what i was thinking

Re: what car uses 3 bar map sensors
 

here is a part number for a Motorola 2.5 Bar Map Sensor at www.digikey.com =MPX4250AP-ND
says their only $14.94 a piece.

Re: what car uses 3 bar map sensors
 

damn, thats not a bad price at all. thanks. i will be getting that one

Re: what car uses 3 bar map sensors
 

----... is that right? That is certainly cheaper than getting it from Xenocron.

Re: what car uses 3 bar map sensors
 

With their $5 handling fee...one unit goes up to ~$20.

Mine come with color coded wiring, clip and instructions. But I know you guys are DIYers :)

Up until about a week ago, Digikey had been backordered on these sensors continuously for nearly 9 months :)

Re: what car uses 3 bar map sensors
 

i never noticed that xenocron had them. i would rather support an HMT sponsor than save $2-3

Re: what car uses 3 bar map sensors
 

truth ;)

Re: what car uses 3 bar map sensors
 

Thanks Phil :D

Re: what car uses 3 bar map sensors
 

2-3 dollars is not the case here.

20 shipped compared to 35+shipping....

::)

Re: what car uses 3 bar map sensors
 

xenocron FTW!

Re: what car uses 3 bar map sensors
 

Re: what car uses 3 bar map sensors
 

www.freescale.com you can sample them for free, just use the part number from that digikey link above.... yeah i'll find some porn

Re: what car uses 3 bar map sensors
 

cool, i will be checking that out.

and now post porn. lol

Re: what car uses 3 bar map sensors
 

they are on 97 and up grand prix's,bonneville,regal. also they are on all silverados

Re: what car uses 3 bar map sensors
 

and what EDM cars use them ?.

Re: what car uses 3 bar map sensors
 

i used the frescale site and got one in like 2 days. superfast shipping and not a penny out of my pocket. they even covered shipping

Re: what car uses 3 bar map sensors
 

GM 3 bar came in '89 Turbo Trans Am, and nothing else.


Motorola 2.5 bar used to be $18/per, plus $5 handling charge, plus actual cost of shipping ($5-9 depending on whatever bottom of the line shipping you chose UPS/USPS/Fedex). That came to $28+ with no instructions and nothing soldered to the pins. Good luck with the Freescale site, hop on it while it's fresh; after about a hundred free 2.5 bars going out they won't send anymore out, ever.

FYI, xenonignog also has carried the JD-approved SMT 2.5 bar variant in the past... it takes an extra hour of dremelling delicately on stock Honduh MAP enclosure to tuck a full sized MPX4250AP inside it so you can smoke high dollar riceboy ass at the streetraces for $$$ by making them think you're running "stock MAP sensor and 10 psi, Y0!"

Re: what car uses 3 bar map sensors
 

wait...what? i want to see this...

Re: what car uses 3 bar map sensors
 

yea, i am very interested

Re: what car uses 3 bar map sensors
 

I don't have any pics handy, but the body is about 1/4 the size of the normal unit. Envision a little flat square of plastic with a small nipple coming up out of the center, and the contacts coming out on the sides SOP-8 style.

Re: what car uses 3 bar map sensors
 

porn has ruined my imagination :-\

Re: what car uses 3 bar map sensors
 

chev vans not sure of the model but that were my brother got his 3bar

Re: what car uses 3 bar map sensors
 

i highly doubt its a 3bar...its probably a GM map sensor, but not good for reading up to 29psi of boost....

Re: what car uses 3 bar map sensors
 

Re: what car uses 3 bar map sensors
 

ok then why is he running 28lbs of boost :6 with no tuning issues, enlighten me im learning about the use of map sensors, im going to run one after my next turbo build and rock 15lbs on stock f22b1 block/w 880 injectors and head studs and 3bar map

Re: what car uses 3 bar map sensors
 

GM only lists the 3 BAR map for that car, and that car alone...

Re: what car uses 3 bar map sensors
 

Your brother got his 3 bar out of a Chevy van alright. The one the dealership uses to deliver parts, you stupid jdm spic------.

Re: what car uses 3 bar map sensors
 

lol, thats funny

anyway, are there any chances of pics of this map sensor setup you have or are there no pics of it?

Re: what car uses 3 bar map sensors
 

haha i just ordered 2 "sample" units. have any info on how to wire them up?
