Ok.. I am pulling the mostly useless guages out of my truck and puting together a single board computer/TFT to run HP tuners full time in my truck. Right now, I have 2 things I need to figure out how to make work.

Oil pressure guage and fuel level guage.

For oil I think I have it figured out. I'm going to figure out the pressure/voltage refference by hooking the sensor up to my air compressor with regulator. Take down a 0psi voltage and run it up close to the 5v taking voltage references along the way. Then I'll run that through one of the EIO's.

The fuel level one is the one that has me trying to figure out how to make it work. The cell I have uses a 0-90ohm sender. 0 being emtpy and 90 being full.

Can anyone explain how to make this work through a EIO?


Thanks in advance
