maximize shift points
What you do is, you take either the HP curve or the accelleration (G) curves and plot them FOR EACH GEAR. You shift where the crossover happens IE when 1st runs out of steam and 2nd "comes on" that point will cross in the graph.
Once you have a HP curve for something specific such as high gear, you can use gearbox ratios to scale the other gears
I'm having trouble finding a www example
This one is G's vs speed. The crossings are obvious in this plot
Here's what we are looking for:

What he did in the graph below is took the engine torque curve and constructed individual curves based on the gear ratios in the gearbox.
