Using the AEM 150psi Stainless steel liquid pressure sensor to monitor and data log your engines fuel pressure and oil pressure is a key part of any serious engine build. These fluid pressure sensors can be found all over Brewed builds as well as our customers track cars. We regularly use at least 2 of these sensor per engine (sometimes more).
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 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. Interested to learn more about how a fuel pressure sensor is used along side the AEM Infinity ECU in our E30 BMW?

Brewed Staff Eric_Brewed –
A good fuel pressure sensor is a MUST have part for any modern build. I tune every modern ECU to reference “injector differential pressure” which is based on fuel pressure and manifold pressure. This is hands down one of the most effective ways at keeping your engine safe even if you suffer from a mechanical failure like a fuel leak or overheated/failing fuel pump.
