HELP!!
I have installed a D180 into a RV8. I have been chasing egt/cht fluctuations since day one.
The problem appears to be in the charging system... turn the alternator off and the readings are stable.
With a freshly charged battery the readings are stable, but after several start attempts the readings begin to fluctuate. I have checked all grounds, wireing, etc. Yesterday I installed a noise filter inline with the dynon power input. This helped considerably, The egt/cht bars are steady, but the digital numbers still fluctuate, but only +-10 degrees or so - they used to go nearly full scale. Also, the CHT readings seem very low, usually under 300 degrees. Any help will be appreciated!! :-/
