By spark curve , what they mean is ignition advance - which , when drawn as a graph , is a sort of curve .
Problem with a distrubuter is - with boost , you (I think) will have to retard the timing and I dont think a dizzy can be made to do that .
Megajolt/squirt will sort that

certon bosch pinto dizys can retard the ig,the ones with 2 outlets on the vac capsule only work,dont ask me how or why,
i know you rig them up as if it was a n/a,if you grind the stop in the dizy it can retard for about 3bar boost,so this ant a problem,
but i am still going to get a megasqurt and go ingtion when i got the cash

Megajolt/squirt will give you so much more control with other inputs available such as water temp control.
Its cheaper than modding a clockwork dizzy and gives you 3d mapping
