I'm glad you have been following the progress. It has evolved into much more than I expected when I first started on it just over a year ago.

Correct, engine oil pressure is not on the CAN bus.

I am using a 150 PSI Honeywell PX3 pressure sensor for oil pressure and a 100 PSI PX3 for fuel pressure.

The Bluetooth sensor server will work with any 5v, 3 wire pressure sensor. They typically output 0.5 volts at 0 psi and 4.5 volts at the max rated pressure.
It does the analog to digital conversion, applies the scale and offset, then sends the data out via Bluetooth.
