Al, et. al.,
The EGT I had in my Coupe was not a TSOed instrument. The FAA guys had no problem with approving it. Admittedly, that was before they tightened up on approving things. Still, the FAA usually seems inclined to approve improvements in instrumentation, even if they're non TSO. I'm impressed with the Stratomaster stuff enough that I bought the Stratomaster Extreme full instrument package for my homebuilt (which I still hope to finish someday). The Extreme is a full flight and engine instrument package in an all-in-one (single failure and you lose everything) package. That doesn't worry me overly much since I hard-VFR and periodically practice flying with no reference to any instruments. Rather than the Enigma, for an affordable EGT for the Coupe, perhaps people might like to look at Stratomaster's Smart Singles like the $160 (plus probes) TC-1 thermocouple temperature display: http://www.mglavionics.com/html/smart_singles.html TC-1 Thermocouple Temperature Display This is a configurable EGT/CHT four channel display. It can be used as single channel, dual channel, three channel or four channel display unit. Each input can be used to display a CHT or EGT channel. Probe types can be configured for standard thermocouples, J or K types. Display for each channel includes a bargraph (scale programmable) and a digital readout. Each channel can have a temperature alarm programmed. The unit includes an uncommitted relay contact output that can be used to switch an alarm light or buzzer as required. Unit does not include probes. Select these as required for the application from our range or use your own probes.
