Big Flapper Posted May 22, 2022 Report Share Posted May 22, 2022 Yesterday one of my Dynon EGT readings indicated -91 deg before startup. After startup it matched the other EGT reading while the engine was running. Is this a sensor going bad or just a connection problem. If it's a failure indication would I be better off replacing it with a Dynon EGT probe or one from Aircraft Spruce or Lockwood? Thanks for any input Quote Link to comment Share on other sites More sharing options...
Tom Baker Posted May 22, 2022 Report Share Posted May 22, 2022 I buy Dynon probes from Aircraft Spruce. I'm not sure if they have the screw in type or not, as I normally buy the clamp type. Quote Link to comment Share on other sites More sharing options...

Roger Lee Posted May 22, 2022 Report Share Posted May 22, 2022 I would just keep an eye on it for a few flights. If it went out it isn't an in flight emergency. many Rotax engines don't even have EGT's. Quote Link to comment Share on other sites More sharing options...
Big Flapper Posted May 22, 2022 Author Report Share Posted May 22, 2022 Thanks Roger I'll just monitor it and see what happens. I agree that I would rather loose the EGT'S before I lost CHT'S Quote Link to comment Share on other sites More sharing options...
Anticept Posted May 22, 2022 Report Share Posted May 22, 2022 The egt is going bad, classic sign. Quote Link to comment Share on other sites More sharing options...
