Possible it may be going open (thermocouple sensors are normally a shorted junction) but also possible you are picking up noise on the leads from some source. These are millivolt level signals so it doesn't take much noise to make a wild reading. Keep leads away from high tension wires (spark plug leads) and lines with a lot of switching current (injector, ignition coil power, etc).

Info needed about EGT sensors, on my RWS EM2 #2 EGT about every 10 seconds will come up as 4000 deg. F. or so. Is the sensor going open or shorted intermittently. Have not checked it yet, just removed break-in oil after 24 hrs. run time & went with 20w50w full synthetic, getting ready for first flight ( got delayed last year by coolant & oil temp readings in-op., solved & my youngest daughter grad. EMU, Meagan & Cody moved to Bloomington Illinois for Cody's new job, with dad as one of the movers ). David R. Cook RV6A Rotary Lansing MI.
