[FlyRotary] Re: Just livid.....

Chris,

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

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

I had to walk away yesterday, take a = breath and focused 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 get = back to the engine directly. I will be checking the MAP table first, 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 away after I found the = bad ground. I fear it may have trashed my serial circuit again. = Donno, just speculation at this point. <sigh> Trying to keep a stiff = upper lip <g>

All the best,

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 = knows.
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 concerned that it may = cause a
problem I would be unaware of. Another testament to my ignorance, = but
learning and better everyday. I shall see what I can do.

I think I may have over crimped this particular connector. When I examined
it, it seemed more cut than crimped. 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
Tracy recommend, IIRC, to be shorter than 12 inches. I relocated my ECU = to
accommodate this instruction.

<sigh>

All the best,
