For what its worth, I tried using the barrel crimp dsubs that came with our GPS when i was wiring up the GPS for our panel, and I had difficulty with continuity on those crimped pins. lots of intermittent connections.

When I went to stamped pins, my connection quality improved from a continuity standpoint.

We wont even talk about the soldered connectors - strain relief probs and technique kicked my butt.

Maybe I will try the soldered ones, but my soldering skills are mediocre at
best...but improving <g>.

Thanks for the feedback.

All the best,

Hi Chris,

Are you using solder pin or crimp pin connectors?

This may be more of a vent than a real question.  However, if anyone has
insight, I am willing to listen.  Also, this is NOT a complaint about the
RWS products.  This IS an admission to my continuing developing skills (or
lack there of) of wire systems and electrical troubleshooting.  Tracy has
always been helpful and willing to provide even basic information.  I post
here first to get the group wisdom and to try to spare Tracy the time as I
am sure that following his travels, he is currently overwhelmed with work
and emails....even though he and Laura have been great to respond to
previous and current concerns previous to this one.  Gee, he is forgoing

OSH

where his presence can provide for the general good of the rotary

community.

Even though it is NOT prevalent on this list, sometimes expressing trouble
shooting and/or proof of concept questions/concepts/experiences etc. some
take the opportunity to go "see, that doesn't work" or makes the yet
uninitiated nervous without realizing that the ability to share online
OPENLY is one of the best safety devices we've got.

Anyway, My engine is/was running much better now that I have plugged some
intake leaks.  The auto tune seems to be playing nice.  However, following

short engine run two days ago, I went to inspect the engine (FWB in my

Velo)

and when I returned to the cabin, the EM2 was flickering.....then it

seemed

to set itself in the calibration mode (and the bottom row of reading are
flickering and fading periodically).  I would try to clear it by hitting
abort and it would flash the main screen for about a second and then

return

to the calibration mode, showing "coolant pressure".  Within the

calibration

mode, the values/modes will change when I press the control buttons as

they

should, however, when I try to get it to the main screen, it goes back to
the calibration mode. My first thought was a bad/sticking switch/es.  So I
replaced ALL four switches to no avail, checked the grounds and continuity
of the wires.  No joy.  Seems too, the being in this mode "calibrated" my
coolant temperature to zero (doh).

When I started the engine (of course one of the easiest starts to date) in
this mode, the engine was surging in a rhythmic pattern, even though

pretty

smoothly.

I am a thinkin' that tonight I will re-terminated all the d-sub pins.

Oh well, back to patrol....and then to the hangar (following a brief

detour,

hopefully brief, to the big Houston dog show to support Jana and the dogs
she is showing.  This is her big hobby and she is usually good about
supporting the plane)

Thanks.  Thoughts are greatly appreciated.

All the best,

Chris
