Strange issue last weekend...
The previous weekend I flew from Portland, Or to Phoenix, Nv with no issues - except that pesky occasional fuel pressure drop that so many experience.
During the week, I upgraded Dyon EFIS and EMS from 3.0 to 5.6 Software.
During flight from Vancouver, Wa to Friday Harbor - both takeoffs saw my #3 Cylinder lose all temperature data CHT/EGT) but then regain temperature after a few hundred feet?? Also of note, not once did I have a fuel pressure drop in 2.5 hours of flight. I have ordered a Kavlico fuel pressure sensor already - but hasn't arrived. But strange I didn't see the issue over 2.5 hours.
But what worries me is the CHT/EGT drop to zero on take off. Engine seemed to run fine with no change in RPM/etc..
This week I will remove cowl for oil change anyway - so will check temp probes/etc..
