That is really conservative. My initial thought was 34-36, but I thought I would start with a conservative number and just say 34. Looks like a lot of others are splitting my window at calling it 35.
The 40 at cruise, that is the equivalent of vacuum advance on top of the mechanical advance. You almost have to get the USB laptop cable to go in and play with part throttle advance to dial in the cruise fully.
I settled on 18 at idle, 36 at cruise and 32 at WOT. It's running really good right now so I am leaving it here for now. Once the engine is fully broken in, I may change some things.
