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.
