I'm in the final stages of completing my RV-7A with only the final inspection and paperwork between me and the first flight. I have fitted the subject engine on the aircraft with a fixed pitch propeller. As you are aware, the Lycoming recommended procedure is to cruise 65-75 percent power for 50 hours or until the oil consumption has stabilized. However, the Lycoming charts are predicated upon using manifold pressure (MAP). Now, I did not fit an MP gauge as I wouldn't need it.
Has anyone else run into this problem and if so, how did you establish your power settings based on only altitude, temperature, and RPM?
Thanks
John
