What's the price on each. Never heard anyone run them in my state. A new homdata 4bar map sensor is 100 shipped. And they're reliable.

I dont think the sensor itself is made of metal but not exaclty sure about exactly how they work....My OMni 3 bar made of plastic works just fine tho

heres the statement directfry from AEM which bassically says to buy the stainless one unless your only hooking it up to a gauge. are you replacing the factory MAP or is this hooking up to a gauge?



Which Pressure Sensor is right for you?

There are many different tools that can be used for measurement, but the degree of accuracy is dependent upon the tool. For example, a ruler can measure distance with a good degree of accuracy, but for a more precise measurement a caliper should be used. The difference between a brass pressure sensor and a stainless steel pressure sensor is similar if we think about it in these terms:

Brass Pressure Sensor = Ruler
Use a Brass Pressure Sensor where you need a good reference to what pressure is being seen.
Example: Brass Pressure Sensor used for a Boost Gauge Reference/Information for knowing manifold pressure, not for ECU calibration.

Stainless Pressure Sensor = Caliper
Use a SS Pressure Sensor where you need exact details of the pressure.
Example: MAP Sensor information for the ECU Calibration/crucial information for the ECU

I'm not hooking it up to a Guage, im using it for the ecu, i have on the stainless aem map sensor now but it's not reading accurately, wen the car is off its showing almost 2psi of boost, so I wanted to replace it with another aem, but I didn't wanna buy back the expensive stainless steel one if the brass one cud work just the same

Well according to AEM they do no work the same, unfortunately I dont have any experience with AEM so I cant speak to the quality. as stated most of us use omni or hondata sensor, didnt even know AEM makes these lol

I have an AEM (have had them for years) and Im not impressed. When they get hot they start to fail. I even have mine remote mounted to the firewall. Have had a Brass, and stainless. They both 'work' for use as a MAP sensor.
