Since we had a rare sunny day up here in  Seattle, I went up flying for an hour after going through the mode 3, 6, then autotune and then a little touch up in mode 9, on the ground. It was running  pretty smooth, but still does not like full throttle- maybe it's still a bit lean up there, but I'm thinking that maybe the Hushpower is too restrictive- I'm flying on  60% throttle, tuning with the mixture knob and the EGT is running around 1700, RPM is ~5000, MP- Damn, forgot to note- maybe 17"?. Funny thing, the coolant and oil is down around 110 f at these settings. Definitely need to block some of the cooling air. I don't know if the Dynon airspeed needs calibration, I did not have my GPS today, but was only getting about 110 MPH at that throttle setting. I did get one thing accomplished- I calibrated my AOA on the Dynon.

 

I'm starting to think about making my own very simple, robust muffler out of 321- pretty much a straight 2" tube within a 4" tube, with some holes and a few very firmly welded baffles. I'll try to get   a drawing out and see what everyone thinks about it.

 

 

At least no one called the tower to report an aircraft in distress this time.
