During a flight today I had widely fluctuating manifold pressure, at cruise it would constantly bounce between 20 and 30 or higher. The conditions of flight were as follows:
YIO360 M1B Lycoming with CS Prop.
RPM 2300, Fuel Flow 8.2 GPH.
Outside air temp 24 degrees.
Cylinder temps were around 290 with not more than a 10 degree spread. EGT was in the 1400 range with about a 50 degree spread.
LOP and ROP operation had no effect on the MP variations.
Interesting note is that I have a smoke system and turning it on caused MP to spike above 30...
I use a Dynon FlightDEK 180 for all my engine monitoring needs.
The engine was running smooth with no power fluctuations or other issues that I could identify.
Thoughts?
