If the serial data link between the EC2 and EM2 is blown = (by a missing ground or other reason) as indicated by the NOP flashing in= the EM2 TACH window, it means that the EM2 and EC2 can no longer c= ommunicate each other.

If they can no longer communicate, that mea= ns the EM2/3 can not possibly know or display what is in the EC2/3 MAP ta= ble. So, at this point you should not conclude that the= MAP table is blown, corrupted, blank, etc.

Chris,

Even if the wire was = not completely separated, it was probably only connected by a couple of s= trands and as it moved (vibrated?) maybe some of the other strands made c= ontact from time to time causing no telling what kind of intermittent eff= ects. Lucky for you, it finally fell apart and you found it.

Perhaps the cause of many problems, howev= er, the broken wire was NOT broken two weeks ago when I rewired the ECU a= nd got it running so well. I just happened to notice it right off y= esterday (gee, what are the odds of me finding something on the first thi= ng I happened to check. Guessin' that will be the last time<g>= ;).

I had to walk away yesterday, take a breath and focu= sed on some micro fill and sanding I needed to do. I at least FELT a bit = productive in spite of the demoralizing impact. I hate the idea of = sending the unit back to Tracy again. He may have had it more than = I have.

I will play with the sanding stuff tonight and g= et back to the engine directly. I will be checking the MAP table fi= rst, but the NOP is what really concerns/bothers me. I am guessing = the bad ground could have been the cause, however, the NOP did NOT go awa= y after I found the bad ground. I fear it may have trashed my seria= l circuit again. Donno, just speculation at this point. <sigh>= ; Trying to keep a stiff upper lip <g>

Chris,
I would = be surprised if you didn't just solve a whole passel of problems
with = your EC-2. There is not telling what that cut ground connection was=
doing over the past. High resistance, intermittent, open..who k= nows.
Fixing this should make your EC-2 much more solid.

Thanks guys. I wrote NOS...course, I = meant NOP.

Hmmm, Al, I considered a second ground but was concerne= d that it may cause a
problem I would be unaware of. Another tes= tament to my ignorance, but
learning and better everyday. I shal= l see what I can do.

I think I may have over crimped this particul= ar connector. When I examined
it, it seemed more cut than crimpe= d. Donno what caused that. I use a ratchet crimper and have not had= problems before, however, most of
my previous crimps were 20 gage and= not 16, so I will check the tool and my
process.

There was no = strain on this particular wire. It is the very short ground
Trac= y recommend, IIRC, to be shorter than 12 inches. I relocated my ECU= to
accommodate this instruction.

<sigh>

All the b= est,
