Chris,
If you have checked your wiring and it is
all ok, then disconnect all the plugs that go to the EM-2 so that you are only
running with the EC-2 and try it to see how it runs. Be sure that the
plugs from the EM-2 can not touch and short out on anything.
If that doesn’t work, then set the
EC-2 back to the factory defaults and try that to see if that corrects your
problem.
Failing that, plug in the spare EC-2 to
see if that works.
By checking all the wiring, you have
eliminated a miswiring.
If your EC-2 works without the EM-2 in the
system, you know the problem is the EM-2 or the serial connection.
If the spare EC-2 works, you know the
problem is your EC-2.
Good Luck!

Yeah, I know mode 8 is for timing.
The problem I am having is in Mode 8 and as I was diagnosing it was also
discovered in mode 1.
Also, I know that the dreaded NOP
is telling me "no operation". I have had this occur before
and it meant a bad serial line from the EM2 and the EC2. I have also
had to send the units back to Tracy
for this issue. However, this time I am seeing the NOP ONLY in Mode
8 and Mode 1 and ONLY when I press the program button. Also, when the program
button is pressed in these modes, the reading for the timing displays
17. Both modes clear and no longer display NOP or 17 when I change
to any other mode. Needless to say, while in Mode 8 and it going to NOP,
no timing adjustment is happening. I did verify there IS spark at the
plugs. ??????
I discovered the problem when I was
wishing to retard my timing after my apparent electrical spike from a
couple of weeks ago adversely affected the engines running. It had
been running great...now, not so much. I moved some wire runs to reduce
more possible spikes, reset the A to factory presets and it was running ok, but
hard to start, thus the timing adjustment.
FINALLY, I have a second EC2. What
say y'all about installing it? If I put it in am I risking the problem
being duplicated in the second EC2? I have spent the better part of the
last two nights rechecking all my wire runs for continuity. Tonight I
focused on the wires to the CAS. I hope to try to start it tomorrow but I
do not think I will have much success until I find this latest gremlin.
I am having a few other issues that need
addressing, however this is the most pressing and the one I am at the greatest
loss.
