AEM Map Sensors above 5 bar

[erikoberdorfer]

Hello,
What map sensor are people using to run boost above the limit of a 5 bar AEM sensor? I see AEM offers a map sensor which goes to a higher level of positive pressure, but doesn't seem to be able to register vacuum. Please share what you are doing. Also, is the series 1 AEM box capable of dealing with boost pressures above 5 bar?

Thanks
Erik

MAP is "Manifold Absolute Pressure". 1 Bar is 1 atmosphere. Less than 1 Bar is vacuum. AEM series 1 can be configured to use any 5v pressure sensor.

The 5 Bar MAP is 1 Bar vacuum & 4 Bar of boost.

As @Mello mentioned above, you can use any 5v linear output pressure sensors by changing the parameters for MAP in AEMPro.
You need a MAP sensor (PSIa), that's the one can measure vacuum. The sensors you checked are PSIg sensors which can not measure vacuum.
AEM now have a 7 bar PSIa sensor which you can measure max 85 psi of boost. The part number is 30-2130-7.

Hiroshi,
Thank you for sharing the AEM 30-2130-7 PSIA sensor. I had looked on the AEM website and somehow missed this. I currently use an aem 5 bar in my 1g, but may need the extra capacity of the 30-2130-7 sensor. This would be what I am looking for.

Mello,
I appreciate the feedback as well.
