The EM2 manual explains how to make your own thermocouples from thermocouple
wire. The EGT sensor I have came with a Westach instrument, but basically
it's just a thermocouple wire hooked to a bolt (probe) which is held in the
exhaust stream by a clamp around the exhaust pipe with a hole for the bolt.
I'm not sure where you could put a second sensor in a turbo installation
unless you drilled the cast manifold. I added a second sensor on the turbo
heat shield.

I should have put in an exception for EGT sensors which require hi temp insulation and inconel sleeves into the pipe.  Don't try this at home.  All other applications - home brew away.
