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
