Racepak Avenger III EGT error code

[Woody255]

Hi folks,

I have a Racepak Avenger III digital EGT gauge. On startup, it flashes the code "No Sno". I can scroll through the set up, but none of the functions seem to be working. I have called EGT, but they no longer service these units. Anybody have any ideas?

Thanks and Happy New Year!
