Interesting, so you're saying that advancing the spark timing gives you more low end torque? And Retarding the timing gives you higher end torque? That seems counter intuitive to me.. I must be missing something about the combustion process.
In my mind I would relate that to pedaling a bicycle. "Advanced timing:" If I start to hit move my feet down to push on the pedal before it came up all the way, I would lose "torque" but be able to pedal up to faster speeds. "Retard timing:" If I wait till the pedal reaches "TDC" and then continues another few degrees forward before pushing down on the pedal, I gain lots of torque which is great at helping me accelerate my bike from a dead stop.
This same theory works with electric motors. Advance to timing to gain revs and upper end torque, and retard the timing to gain low end torque but sacrificing rpms.
Or do combustion engines work totally different than that? Wow that would shake the foundation of my understanding of physics as far as engines go.
