After setting the timing using the minimum chamber volume method,  the spark plug life has increased along with the time it takes SAG to develop.

 

That is interesting.  Since I see no noticeable change in performance by reducing timing a couple of steps; perhaps it’s worth doing to increase plug life. Although it may be less an issue burning mogas.

 

I found that I had been operating at 35 degrees BTDC at 5200 RPM and 23” MAP with the default controller timing setting and Tracy’s recommended CAS position.

 

Tracy; If you happen to be following this – based on your advance curves; how much advance would you expect at these conditions?
