I have dual electronic ignitions = in my Lancair 360 and have done a bit of testing, but until I find a = copilot willing to spend hours in the air with me I won't be able to = gather as much info as you have. My dual electronic ignition is PC controllable, and I have done quite a = few changes to the timing while flying. I typically run a few degrees = less advance than stock in take-off mode but run mid-30's in cruise = settings. Adding a degree or two of timing (from low 30's) did help a = knot or two... maybe. But after that the benefits really diminished. I = could probably add 10 to 15 degrees MORE advance and still wouldn't have = a detonation problem in the cruise mode. =20 Come fly in NC some time and we'll hook up the laptops and run some = tests...
