Hi all,
I've listened to Mike Busch's webinars and such, and have gathered that EGT is meaningless on a non-turbo Lycoming, and is simply a point of reference for setting fuel flow.
That said; at low altitude, LOP, my EGT's are around 1550 F, which turns my G3X engine monitor from green to yellow. I can reset this threshold, but before I do I wanted to make sure I wasn't missing some limit.
I know in turbocharged installations 1650 is generally referenced as maximum turbine inlet temperature (TIT), but I obviously don't have a turbine to worry about. So, is it safe to say that my EGT's of 1550 are completely fine, and I should just reset the yellow caution to 1600 degrees, and the redline to 1650?
The high EGT's began occurring when I timed my PMAG's 1 tooth after TDC, which makes sense. Less advance = higher EGT's, and lower CHT's.
TL,DR - Is it acceptable to set the caution and warning ranges on the G3X to 1600 and 1650 degrees respectively, or are EGT's in the high 1500's something to be aware of. I don't want to unknowingly cause damage or excessive wear to my exhaust components.
