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. ---

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 ---

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

> [@RacerX](#): > > The S14 is a maf car. What are you using to eliminate the maf, translate the map? 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 -Mike
