Operating  ROTAX 912 ULS.
Intermittantly, during ground engine operation and in flight, red EMS panel light flickers just briefly, followed by two messages on both Skyviews that display "Tach Low" and "EMS Fail." The messages extinguuish after a few seconds, only to repeat the sequence a few minutes later.
Anomaly is not present until engine is started and running.

Note:  EMS module was replaced and symptoms still remain.
Tomorrow, I will send another diagnostic file to Dynon.

Anybody else experience this phenomena or have any ideas? Sad
