Chris,

I have an old EC2 in working condition.  It was used to run the 13b engine. When I changed engines for the Renesis, I could not run it with the EC2 because of the crank angle sensor difference. So I got the EC3 and that solved my problem.  The EC2 was running fine with the 13b engine.

Jeff makes an excellent point.  I also just unscrew the lid and carefully
wrap it in Anti static plastic, pad it well in a box with bubble wrap and
ship that - I leave the case (as does Jeff) attached - makes the "hell hole"
less hellish.

Thanks Ed and Bob,

The insight is appreciated.  Every experience educates me more.  To
paraphrase John Slade, if the me of five years ago could see the me of
today, he would be impressed by my knowledge....even with this type of
trouble.  I am more confidant of my knowledge and better yet, my ability
to more truly understand.  Thanks for breaking it down so clearly.

When I post my questions and/or share my experience it is reassuring
that while I may receive a couple of (hopefully well meaning) knocks, I
am always quite certain I will get solid information that actually
helps, educates and moves the process along.  Even when a complete
answer is impossible, it almost always gives a starting point.

Yes, Ed, I am all for it breaking on the ground.  Keeps it as a mere
frustration.

So, back into the "hell whole" to remove and ship my ECU.

All the best,

Chris

Hi Chris,

Ed painted a pretty clear picture of why your serial link may be out.
I think one point Tracy made about the problem needs to be emphasized.
Without the serial link, you can't read anything from the EC2.  The MAP
may or may not be flat lined, and you may or may not be making changes
to it.  Without the serial link, you just aren't getting any data from
the EC2 to the EM2.  You may be getting RPM and fuel flow readings as
that data is read from the pulse to the rotor 1 primary fuel injector.

If the serial link were working, it would only provide MAP data from
the A controller.

I made it out to the hangar tonight and attempted to reset the EM2.  No
joy.  It would not reset and I could not get it to accept any changes in
the MAP table.  It is all flat lined.

I will likely not get a chance to further investigate wires until I am
off on Friday.  I did not see anything obvious other than the ground
wire that was broken but I shall  investigate much  further.  Of course
I am bothered but perhaps more concerned as to the why.  I do not want
to send the unit back to Tracy again, just to hook it up and it blow
again.  As I mentioned, the engine was running really well before I
started concentrating on the planes finish.  I felt pretty good that
after a couple of big set backs over the last two year that I was
finally on track.  As a matter of fact, I felt this has been the first
time I have actually been able to use the EM2/EC2 as it should be used
since I can't blame the EC2 for coolant in my rotor housing or bad
Jeffco in the tanks.

So, to maybe ask a couple of obvious questions....could the one bad
thick ground wire breaking completely "toast' the EC2?   I  know it is
difficult to make hard and fast rules, but this seems pretty
catastrophic for a single wire break. <yikes>  Also, if I change to
Controller B, will I be looking at the MAP table for the B controller?
(if this is flagrantly stated in the manual, I have read past it as I
focused on other issues).  Okay, I have a few more questions, but my
brain is a bit too fried/disappointed to form them right now. <sigh

again>

So, uh, Tracy, do you have an old EC2 laying around I could buy, that
way I can be trashing/working on one while your repair the other.  I am
not kidding, you have any old stock of EC2's?

All the best,

Chris
