i have the lunar autometer gauges and ive had them for about 6 months and now im starting to have trouble with my egt gauge not working sometimes and it seems to me that its not working like when its cool outside and as the day progresses and gets warm outside then it will start working again. i was wondering if anyone else had this problem with their gauge doing this.

yea i had major problems with mine. i would give them a call. it has a 1 year warranty so you are fine. they will probly tell u to find a better ground and if it doesnt work, just send urs in and they will take care of you.
