John, Ed, et al.
Let me echo Ed sage advice. A year or two
ago, I had cross wired two wires to the control module which caused problems
similar to what John discribed. Chase the wires. I hate chasing wires, and
just do not want to do it. So I do it last when I should have done it first.
Lot’s of wires give many
opportunites for errors and all on my many problems with tuning the engine have
been the results my faulty soldering, crimping or such.
BTW. I just found a faulty crimp in a ¼”
slip on connector. This set the stage for insufficient/ intermittent voltage to
get to the leading coil. This was the source of months of trouble which I
tried to blame on the EC2 and other stuff. This connector looked great and
passed the tug-test, but it was not making good contact internally and sent
only 6.3 volts to the coil. Chase the wires and get rid of all suspect
connectors. “Solder all connectors” is a good rule.
Best Regards.

If none of this has any affect, then I suggest you
recheck your wiring AND your connector pins. Check to make certain that
none of those fine strands of wire have cross over and touched another pin in
the DIN connector. Either with a magnifying glass or at least run
something around each pin to make certain you don't have two connected
that should not be.
