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, 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.
