That's the correct hook up. Steve. The old diagram
had 10 going to 10 and 24 to 4.

Tracy,
The schematic that I have shows Pin 10 on
the PCM going to pin 24 on the EC2, and pin 10 of the EC2 going to pin 4 of
the PCM.
Steve
One more thing Steve, I can't remember how early or new your EC2
is. The early instructions had an error in the EC2 to PCM
connections. Corrected instruction were sent to all affected users.
The version in error showed pin 10 on EC2 going to pin 10 on the
PCM. Check this out and make sure it's not in error.

Tracy,
You're right about my misunderstanding
of mode 1. That will probably resolve allot of it. I've also
received other feedback on mode 3 being a fairly fine adjustment, so maybe
I just didn't push it enough times. I thought that I had read that
it would only take 3-4 hits though.
As far as the wiring goes, I double
checked them pin for pin when I wired it, using a helper and an
ohmmeter. I'm pretty sure that they are right, unless one has come
loose. Mode 1 definitely works, because I definitely saw a
difference when pressing the store button. I really haven't
programmed any other modes, except for 4 hits on mode 3. I really
didn't see any difference, but maybe I should try a few more
pushes.
Steve
Steve, go back and read the instructions on Mode 1. The
operation is different than for mode 3. In mode 1 it does not make
any difference how many times you hit the store switch, only the
position of PGM (left) knob determines the correction value used when
you hit the store button. Also see Mode 9 which is similar to Mode
3. Know the operations of the various modes by heart before tuning
the EC2.
Remember that Mode 3 is a fairly fine adjustment. It takes
about 25 clicks on the store switch to run to the end of the range in
either direction.
If Mode 3 doesn't make any difference it means something isn't
right and you should stop everything and fix it. Do not taxi, do
not fly, do not pass go, you get the idea. I would suspect a
wiring error in the connections between EC2 and PCM panel. It is
likely that NONE of the programming modes are working based on your
description of tuning results.

Tracy,
I have leaned mode 1 as far as it
would go. I can turn the mixture control to about 8-9 o'clock
and get the correct mixture. I tried mode 3, and it does;t seem
to do anything. While watching the air/ratio gauge at about 2000
RPM's, left knob at 9 clicked the store, no change, clicked it 3-4
times more, still no change. This was with the mixture knob
at about 9 also, so I could see any change on the LED bar graph of the
ratio gauge.
Mixture seems to be rich at every
setting, but better at higher RPMs. Lower RPMs are really
rich.

Archive: http://lancaironline.net/lists/flyrotary/List.htmlTo make any meaningful comments I'd need to know if you tried
the easiest things first. If the engine is running too rich,
did you turn down the mixture control? If so, what
happened? If that wasn't enough, did you reduce the injector
flow rate? (mode 3). Is it rich at every throttle setting or
just a few?
Sounds like something has gone bad with wiring on the coil test
issue. Sounds like you still have power to the injectors when
you turn the EC2 off causing it to continue running. Correct
this right away if so.
