calling all knowledgeable 2smokers, brace your self .. 3d ignition questions!

[Reino]

In the next 3 years i would probably have gathered enough money to start my project (don't ask its a secret till its done).In the meantime i am doing research especially on 3d ignition maps, but so far i have not yet found a collection of 3d maps or good explanations on what happens under load in 3d maps.I am replacing the cdi on my 250sx with a system that can do anything so it would be a shame not to use a 3d map.

my questions:

1-is a 3d map worth it

2-what happens under load

3-how would a 3d map look like (i am well informed about 2d maps)

I live in Namibia (just above South Africa) so because of my time zone i would probably take a while to respond.
