That custom sensor accommodation of the G3X is great. I have readouts for showing timing of my Lightspeed ignition, and evaporator temp and hi-side pressure of my A/C system.
Interestingly, our 2003 Silverado has a
Kavlico oil pressure sensor as original equipment, even with the same plug as we use in our airplanes. At 60k miles and 10 years, it started reading low and had to replace it.
