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.

 

Thanks,
