EGT issue

[Bo_Hannington]

I have a D180 in mt RV6A, been working fine for years. Suddenly yesterday all 4 EGTs read wrong. They all seem to read approximately the same value of 541degC, but there is a few degrees of jitter. They never read greater that 541degC. Normal cruise EGT reading has been in the 700 - 800 range.
Tried again today, reading correctly before start, warm up okay, but same thing, they all limit at 541degC.
Must be an internal problem for all 4 to suffer, I would think.
Any comments, or solutions?

Bo, that sort of ‘failure’ needs direct help from support@dynonavionics - I don’t think it’s an in field fix.

Thanks Jake, was wondering if it might be at all useful to reload the firmware, but in my experience this feels like a hardware failure. The problem is the freight costs and the time it will take to get it fixed.
