I have been working and refining little details of the School Bus.
Worked on the fuel system a little last week and seem to have it dialed in a little better now.
This was after about 60 miles of level flight with the a/p flying and everything stablized.
Fuel flow is 11.8 running 179kn TAS at this altitude LOP. I am still testing and contemplating tuning #5 cyl as you can see it is quite a bit leaner than the rest of them and is always the first to peak.
It appears to make about the same speed on approx .4-.5 GPH less with each 1000ft of increase in DA but I have not yet made a chart to reflect that. I might do it in the future.
Sorry about the picture being choped off at the top. It is running 23.4in MP.
