This is an attempt to tap into a wider list knowledge outside the
'Diesel Vanagon' forum....

Question:
        Is there anyone out there who has installed an EGT gauge who
has concerns about the accuracy of the gauge.

        I ask this because I was reading on one man's blog about his
installation of an EGT Gauge...Quote.."The leadwire from the
thermocouple (it's a special wire, don't cut it to lengthen or
shorten and don't solder the connections)"  Unquote...

I had excellent feedback (from Diesel-Vanagon) on why not to
cut/extend/solder/screw up the supplied wire harness, but no clear
solution to the problem. I can't believe that of all the people who
have installed these pyrometers that each and every one, did the
'correct' thing and purchased 'special' wire or calibrated the gauge.

Perhaps someone on the list has a source for this wire. I bought the
'kit' from "eGauges"
http://www.egauges.com/vdo_mult.asp?Type=Pyrometer&Series=Vision
and they don't list longer wire of any length. (24' wanted).

        Unless I can find the 'proper' wire, I think I will have to
set up a bench test and actually 'calibrate' the gauge using a stable
heat source set to accurately pinpoint 1000 degrees and use that as
an installed reference point.
