Using the AEM 150psi Brass body liquid pressure sensor to monitor and data log your engines fuel pressure and oil pressure is a key part of any serious engine build. AEM fluid pressure sensors can be found all over Brewed builds as well as our customers track cars. We regularly use at least 2 fluid pressure sensors per engine (sometimes more). For customer that want the most accurate AEM fluid pressure sensor we recommend using the Stainless steel body pressure sensor AEM 150psi oil & fuel pressure sensor.
Any customer using one of our plug n play Motec, AEM or Haltech ECU packages can also take advantage of using these pressure sensors for engine protection strategies and fuel trim compensations. These features allow for better tuning and a more reliable over all engine package as the ECU is able to monitor and use the live fuel and oil pressure data within our custom ECU calibrations. Below you can see the AEM 150psi Stainless Steel body fuel pressure sensor on our SR20det swapped E30 running our AEM infinity ECU package.
The 2 main uses for these 0 to 150psi sensor would have to be oil and fuel pressure. Combine these sensors with one of our plug and play ECU packages for Motec or AEM Infinity ecu’s and we can calibrate the ECU to use these sensor values as engine protection features. This means if oil pressure drops we can cut spark/fuel and save the engine from damage. When used for fuel pressure we set up the ECU to drop boost as soon as there is a drop in fuel/injector differential pressure. We also setup the ECU to calculate fueling based off the fuel pressure sensor which keeps the engine running on the target AFR and drops boost to relieve stress on a fuel system that is starting to loose pressure during a full power pull.
