I know it's just idle but still seems crazy low to me. The real problem is they don't even generate that much pressure at redline compared to a lot of other cars.
I plan on getting a gauge at some point but I want to get one that I can interface with my Raspberry Pi so I can have an intelligent warning light where I take into account RPM and oil temp rather than some static number. My plan is to connect the RPi to the reverse camera input on the OEM head unit and then rewire the reverse line to my RPi. Then if I ever want to display a warning I simply trip the reverse signal and then it will display on the head unit.
Here is the guage (sending unit) I was looking at:

Problem is the RPi doesn't have analog input so I need to look into an analog to digital converter or use an Arduino instead of an RPi.
