The injection system is in and operating. Took way longer than expected as the annual inspection ran a little long with a couple issues that needed attention. After some initial engine driven fuel pump configuration issues were resolved the first test flight was conducted today. I am stillgoing over the data to see what the changes are, but here’s what I have seen so far. The engine runs a little rougher at idle than it did with a carburetor. Not bad, not that noticeable, but obvious when comparing data read outs from carbureted to injected. It looks like there is a very narrow power setting band (near idle) where the 5 and 6 cylinder run lean resulting in an egt temp differentialof over 300. The engine now produces a little more than one additional inch of MP at full power than it did when carbureted. At cruise (23 MP, 2400 RPM) the engine has a temp differential of 37. Very smooth. I did not do any serious leaning yet. More to come.
