Can someone please tell me how to wire me gm 3 bar? Its going in my 91 civic can find a write up anywhere.
thanks

 

SEARCH. This took me 30sec to find.

Pin A -- Ground ---- Honda Green/White
Pin B -- Sensor output--- Honda White
Pin C -- +5 volts ----- Honda Yellow/Red

 

ok where do i find me one of these i have done some searching for about an houre and this is the first thing thats even close so what cars/trucks do they come on

 

google it
only one part number is right

 

Ya, you must suck!! Type in GM 3 bar in google and you get tons of ----!!!!
EBAY has tons.
Or you can go to Digigkey and get a 2.5 for about a third the price.

 

see actuly im looking for the kind i have vehicles that they come on because i have acsess to all kinds of ---- at the wrecking yards around here. so i was trying to find what i can pull it off of for basicly free

 

Again Google will tell you!

Basically only the Buick GN and Turbo Trans-AM. Good luck finding one of those in the Junkyard!

 

I bought mine from Summit Racing online. It was a MSD 3 bar for about $55

 

i can get a 2.5 from a sun bird turbo and i might go pick it up on like thirsday or friday

 

Please just don't a 2.5bar is the same as the next.

Different Map Sensor output different voltages at different manifold pressures.

The Digikey Motoralla Map works. Find the manufactures web site to get the voltages vs. pressures, the you have to find the GM 2.5bars voltage vs. pressures. If they don't match, there probably wont be a .bin for you to tart with.

ALSO: There is no 2.5bar Sunbird MAP sensor. It's a 2bar which is basically no upgrade from a stock honda.
