Oil pressure indication with engine off

[rwtownson]

I am just in the final assembly stages of my RV-8. 

While confirming operation of my Skyview I noticed that it is showing an 88 psi oil pressure.  The engine does not even have oil in it yet...  Also noticed later that my fuel pressure is also indicating a reading.... Other things, temperatures etc seem to indicate what one would expect to see.

It seems like it could be:
- faulty sensor(s)?
- calibrations I've missed?
- wiring errors?

Any idea what's up?

So first, which oil pressure do you have connected? Is it the VDO style (silver bell looking thing) or the newer Kavlico (gold short/stubby thing)?

 

[Dynon]

Also, under the EMS SETUP > SENSOR INPUT MAPPING, what does the oil pressure sensor row look like (typically this is connected at C37P7)?

The kit that I purchased contained Kavlico sensors for a Lycoming O-360.  I did not note the numbers on the sensors before I installed them. 

Both oil and fuel pressure sensors were affected.

This was the mapping that was giving problems...



Today I guessed and changed to the mapping below which gave me zero readings.  I am still uncertain however that these are the right sensors as the numbers I was able to see on the sensors do not match any of the selections.  Unfortunately I left the sensor numbers at the hangar...

This is the mapping I tried below, not that clear unfortunately.  The oil was set to Kavlico 150psi (101693-000) and the fuel to Kavlico 50psi (101716-000).  Am I close?

If it's an O-360 (carbureted), then oil pressure would be 150psi (101693-000) and the pressure would be the 15psi (101690-000).

If injected then the fuel pressure would be the 50psi (101716-000)
