which map sensor?

i’m looking to run a max of 10-12 psi for the time being, so i’m not sure if running the aem 3.5 bar would be necessary. but i cant seem to find the 2 bar sensor that aem used to offer anywhere. id rather stay away from the gm map sensors if possible. any input/advice? thanks

s14 w/ ka24de btw.

motorola 2.5bar from digikey

They sell our MAPs? :lol: I did not know that. Let me look it up and see what model it is. Maybe I can get you better info on it.

i was hoping for something that AEM has already tested and has all the scalars and filters set up for. i did find a few sites that offer the AEM 2 bar, but its around 150 bucks as well. this is something id rather not cheap out on, but a $50 gm 2 bar is looking pretty tempting right about now.

You would be crazy not to purchase the GM 2 bar MAP sensor. They are very durable and a lot of aftermarket FI systems use or are based on the GM/Bosch MAP sensors. Also the calibration charts are readily available online to convert the 0-5v output from these sensors

Plus if you are only planning on running 10-12 psi you don’t want a 2.5 or 3 bar MAP sensor because you will only lose resolution

isnt 12psi still under 1 bar? i thought 1 bar was 12.something

7

it has to read vacuum too, so you need a 2 bar sensor to run 1 bar of boost.

8

1 bar = 14.5

so a 2 bar sensor reads from -14.5 to +14.5

do these p/n’s look right for the gm 2 bar and harness? ive found like 6 different ones, most of which seem to be discontinued.

gm p/n:
map: 12569241
harness: 15305891

ac delco p/n:
map: 213-1520
harness: pt1035

16009886 , I think I have one laying around here I will double check the number for you

12

14.68 rounded up to 14.7 usually

13

The S14 is a maf car. What are you using to eliminate the maf, translate the map?

14

the obd2 s14’s actually have a mafs and map sensor oddly enough. i was using the stock map with the aem ems, but it is only a 1 bar sensor.

If you want an AEM 3.5 Bar MAP I have it in stock.

OR

The following GM MAP sensors are available in the current wizard file for AEM Pro:

GM # 12223861 - 2 bar MAP
GM # 12223851 - 2 bar MAP
GM # 12223861 - 3 bar MAP
GM # 12219935 - 3 bar MAP
GM # 16040749 - 3 bar MAP
