ignition modules. custom, homemade or programmable?

anybody ever do or see cool ways to build your own ignition module? i know msd is an option but it doesnt do what duraspark does(it can but $$$ will be spent)
anybody have a link to cool schematics or anything?

that or can you add extra things to a duraspark? ive heard of add-on cdi boxes but is there a way control timing or other cool stuff?

i think it would be KA to be able to customize and be tunable, especially on the fly!

sorry if this is too geeky for this forum!lol! i just think outside sometimes rather than just about fixing/restoring

Closest thing I can think of that might interest you is a Megasquirt ignition. Hand built and programmable. I remember building a lot of stuff out of Popular Mechanics and Popular Science magazines back in the 70's. Most info is proprietory on existing stuff. I've looked and never found a internal diagram for a Duraspark box..

back when i was big into the mazda forum those guys were all the time using the megasquirt, which i think would be ideal but when i looked at their site it looked like it was all designed for efi, ill have to look more into that.

it sucks that theres no schematic of a duraspark box to start with

You can use a GM 4 pin control module for a HEI and it will work with the duraspark.
