Way before I had done the megasquirt, i had datalogged the ignition timinig advance, and my values below 100 kpa, are really close to stock timing. At cruise on the highway( roughly 30-50 kpa, and 3200 rpm), i logged in around 34-36 degrees of timing. Take note that the stock ECU is set for 87 octane, and 9.6:1 compression ratio. Most of us are running 92-93 octane, and lower compression, so that right there means we can run a few more degrees of timing in vacuum conditions. Under boost, the stock ECU puts in an automatic 14-17 degrees, which i found was the limit at 15 psi on 93 octane before detonation. I found with lower boost on 93, at 10 psi boost, a good timing range is around 21-22 degrees, and increase the timing as rpm increases, in 1-2 degree increments. There is physically less time for detonation to happen in higher rpm, so you can ramp up the timing as it gets above 5000 rpm.

The large gap in timing from the 3rd bin to the next, is because you want to keep the timing advance equal all around the idle perameters. This helps keep the idle steady and from jumping timing advance all over the place.
