EGT's are thermocouples.. they measure the temp at a junction of two wires.  Whenever you create a splice onto the thermocouple leads you introduce another junction that can serve as a thermocouple. Best solution is to have a single long lead that runs all the way to the device.. buy it that way. After that.. trouble shoot grounds..

Kelly,
 
I don't know what my EGT's were when I ran it up the other day. My EGT readings have not been working properly and I have yet to determine why or a solution as of yet.

Way to go Chris !!..........I  (years ago) needed to learn to weld for my "Dyke Delta" project (which is
a weldors nightmare)...............The Delta was so intimidating that I choose to build a  "Cassutt" first 
which is a much smaller welding job to hone my welding skills...................I like you found Gas / Oxy
welding skills were relatively easy to pick up and surprise "Enjoyable".......I have since also acquired
a "Lincoln" 175 tig and found this skill easy to pickup as it is similar to Gas/Oxy with a different heat
source.............
 
On a different note did you notice what your EGT reading was at 6450 rpm and 34.5 MAP ??..........

Well, yesterday actually.  I completed the EAA Sport Air workshop yesterday on Welding.  While I know the Gas Oxy method it just a BIT antiquated by all the new stuff, the class removed much of the mystery involved.  I was amazed at the progress made in just two days.  From dripped, blotchy beads, to "not all that bad", somewhat consistent beads. 
 
I know it is not much of a leap for many of y'all, but I always felt quite lacking not having a base understanding of the process (videos and books just do not breach the gap).  Now I will be looking for a Tig course, or even, now with a basic comprehension, even a friends input.  The Velocity is not a big welded craft, but there were a few things I would at least have entertained, even if I would have farmed them out anyway.
 
On the rotary front, since I dedicated a bus for just the EM2/EC2 and reinstalled the units in the plane (currently using Rino's old unit since the wiring is correct for it...my unit has a pin difference being a later unit), I am currently NOT having my tach dropping out at 6000 rpm (so far).  Last night I did a quick run up after leaving from the welding class and ran up to 6450 rmp static at about 34.5 MAP.  I had trouble holding it with the brakes...and this was on rough asphalt.  I hope to get out there in a bit and do some tuning and RE-determine best cranking settings.  It is starting quickly when cold at full rich mixture.  Gotta keep it a full mixture for a few minutes till it warms.  However, it is taking quite a bit of fudging around to get it to start hot.  Per Mistral, my injectors are large so I think I may need to go leaner (about 10 o' clock currently)  when hot...or so my preliminary feeling is such.  For those who are not there yet, you pretty much have to start over with base mapping every time you get your units back from Tracy.  Of course, I am getting much better at it...... ;-)
 
All the best,
