Mark,
You raise a good point.  I'm pretty confident in the oil side of the equation.  The digital readout is aircraft certified, and the specs are +- 1/2 degree.  The sender is also aircraft type.  The water temp is automotive.  Its anyone's guess how accurate it is.  The sensors aren't real expensive, so I may just order another one, and see what I get.
The engine doesn't seem to be really hot when I land, which also makes me wonder about the accuracy.

With that said, I also think that my air flow through the oil cooler is a little on the low side.  I don't want to rob any more form the coolant side, so another scoop seems to be the answer.

Steve, can’t you put the sender in boiling water and see what do you read? Many gauges have adjustments on the back and you can compensate if the reading is off.

Steve –

Make sure you do this (hot water test) while the sender and gauge are attached in the plane. If there is a “ground loop” problem (i.e. significant difference in resistance between sender to ground and gauge to ground) you might be getting an error that way too. If you test them out of the plane they may check out OK but in the plane they may have this additional error.

 

Just a thot!
