Fuel pressure sensor

I have a three-wire automotive style fuel pressure sensor/sender 0-5 volt with signal wire. My Discovery Lite EFIS set to this style sender reads 7.7 psi with nothing hooked up.

Fuel readout on the EFIS

I'm trouble shooting fuel gauges on a Descovery Lite installed in a Zenith CH750stol aircraft. One tank is nearly empty the other half full. I ohm'd the wires at the RDAC unit and get two different readouts that suggest the senders are working. On the EFIS display both tanks show empty. So I tried f...

EFIS screens

Can Michigan Avionics or anyone for that matter edit the Discovery Lite screen for me. I have the simulator and have tried editing the screen myself but when I exit out of the screen it goes back to the default screen.

Re: EFIS simulator

I can't get the simulator to save my work is the problem. When I go to Module - select default engine module - make changes to suite my engine and when I exit shouldn't my changes show on the simulator screen?
