Chris,
Do you have power to the EC-2? My EM-2 flashes NOP when I have not turned
the EC-2 on. I don't know what the MAP table would look like with the EC-2
off. Maybe bottomed out?? Perhaps more broken wires???

I turned on the EC2/EM2 last night and as expected the NOP is flashing at
me, laughing at my meager attempts to get my airplane airborne.
Also, I checked out the MAP and everything is flat-lined. All the bars are
all the way down at the bottom. Normally, my engine runs well with all bars
in the middle (at 0). I did not look at the actual numbers, but I think it
must be -127 (is that right). I saw everything down at the bottom, and went
back to sanding my cowlings and wheel pants.....for now.
I guess I will try to reset to factory defaults (which is where it has been
running well so far) tonight. See if it even takes the reset.
<sigh> In the past, the NOP meant a trip back to Tracy. <heavier sigh>
(plus trying to figure out the why (broken ground???....but what else, if
any) <even heavier sigh>
All the best,
Chris
