will i need to get a 3 bar map sensor to run 12 lbs with the AEM EMS, or will the stock map sensor work? thanks for any help!

 

I wanna know also

 

stock is good to abt 11 lbs 3 bar is good to 28

 

some have run 10, some have run 12 just fine. depends on the construction of the individual map sensor, but usually 11psi is the swith-over point...

 

try it at 12 or whaterver and if it doesnt work go for the 3bar GM or aem. you have to go to the aem website forums and get the new data entered in to the table so you can use it. go to the site and do a search for the map sensor junk and you'll get all the info you need.

 

You say the GM 3 bar map sensor ????? I used to use the ERL-FM2.... I believe it came with a GM map sensor. It has a 3 wire plug.

Is this the same 3 bar you guys are talking about?????

You can run 12 psi but youll be at the max range of the stock sensor. I'd go 3bar just for safety sake (its realatively inexpensive).

the stock sensor wont read 12 psi.....i think its like 11.43 psi or for my car anyways.....

 

they all have three wires, ground, power, and sender, so im thinking if its a GM 3bar sensor then is the one that reads 38psi im guess since its called a 3 BAR map sensor

11.43...12...11...whatever. i wouldnt push the stock map sensor past 10 psi. ...intentionally

 

so im gonna need a 3 bar

do any of you guys know the GM part number for the 3 bar? i cant find it

thanx

 

search, i looked, found a post by ArTurbo, and bought one through that info the other day. Cost me $82.50 w/pigtail and shipping.

 

part number for the sensor is GM 12223861 (90$) and the connector for it is GM 15305891(20$) but you can get that connector from some other GM car at a junk yard iv seen that same connector on a rx7 O2 plug so just look and you'll find

 

thanks

 

Anyone know if the ERL system comes with a 3 BAR GM map sensor?????

 

any map sensor off of any 89 firebird or Trans am will work
