I've recently purchased a P2002 EA Sierra with a VP prop and a Smart Avionics CSU.
Would anybody have some guide figures as to RPM to set on the prop and MAP for various stages of flight?
We've been flying the aircraft the last few days and were wondering if our settings were common.
E.G. Climb 5400 rpm and 28 MAP and cruise 4800 rpm and 25 MAP.
Any advice appreciated, thanks.

I have an Airmaster CSU with factory setting of 5750 for T/O, 5500 for climb and 5000 cruise. They are adjustable but seem right to me. I generally cruise at 26 MAP. Your 2400/25 seems low but will give good fuel economy, however is your oil temperature high enough?

OK thanks. My settings are the same as yours. Not sure where you got 2400/25 from?

I've no idea either! Sorry I meant 4800/25.
The Airmaster also has a setting for 4800 which I use to slow down for turbulence with MAP at 24, but I find the oil temperature gets a bit low
