Again, the OAT sensor is to be
connected differently from the other air temp sensors, because it
needs to be able to sense below freezing. I think it's ground is
at 0.5 or 0.7 volts.
Rinn:
I’ll check again, but i’m
pretty sure I grounded EGT 3/4 since I’m not using those at
this point.
All three LM 34-DZ air temp
sensors (for OAT, Aux Temp 1&2) are all hooked up per the
manual, and “should” be accurate (according to the manual),
but they aren’t. I asked the last question because the manual
doesn’t say anything (that I’ve found) about what might cause
completely bogus values (could it mean the LM 34-DZ is bad)?
At this point I’ll go into
the calibration and adjust that, and see if that might help,
and if it doesn’t will solder another LM onto the three
wires.
Thanks again for your
inputs!

What
do you have connected to EGT3?
I'm using EGT3 for water temp so will show 3
if water temp is higher than EGT1 and 2
(like after running and cool down).

Group: My temp
readouts seem to be reasonable so far
except the OAT (+\- 64), so was
wondering if any have seen this before?
Also on the main screen I noticed next
to EGT bar graphs a single digit
(instructions say that’s the highest
temp rotor), but mine displays a “3”
once in a while, so it appears mine was
programmed as a 3 rotor vs. “2”?
