Back from our little trip to New Braunfels for Wurstfest so I've now played with my model a bit.
13* fixed advance
Vacuum advance cuts out with closed throttle (idle and decel)
Added Hg inches (gauge) for reference to kPa for engine load
Broke out the 3 separate sources of advance into separate tables to see effects (centrifugal advance (RPM based), vacuum advance (load based) and static)
Set centrifugal advance to same as manual - all in by 4000 RPM, not 3000. Unknown if linear, most springs are not.
Does this look more reasonable? I know that just a couple of degrees of timing can have a 5% or so impact on HP, so before spending big $ on dyno runs I would like to get as close as I can. The values I'm actually running aren't far from this.....
