A question on electronics

Is  this control boxes only function to pulsate the power to the coil?

Usually this sort of setup is done with an extra fuel injector as well.  Push a button get big flames.

A little more trickey when you put in extra fuel. I am not totally convinced that there needs to be a pulsating spark for this system to work. I assume that the control box is for the control of the pulsating spark as well as an expensive splice box. Comments (pro/con) the need for a pulsating spark?

Actually, a flame thrower is simple to build with a HEI ignition. Add a standard coil with spark plug & bung at the end of the exhaust pipe. Simply splice in a toggle switch(ON-OFF-ON) with each 'ON' feeding each coil. You will then 'toggle' between ignition and 'flame'..... by that I mean to build sufficient engine RPM's, then 'toggle' to flame, step on the gas(I run a 4 bbl), and voila, FLAME. I built this into my Koenig 2 yrs ago because I was tired of pickup trucks being a foot rearward of me, trying to see/climb into the engine bay..... makes for a good surprise!!!
Get rid of your cat, as the cat will try to absorb any unburnt fuel ! If you want a real long flame, add propane!!!....warning... the rear of a Fiero can get very hot.... carrying propane is like carry a bomb! I have never liked taking the BBQ bottle over to get filled!

A pulsating spark minimizes the chances of a flame-out.

Cruder yet than Sandy's suggestion, is to build your own hardware with a on/off switch, relay, ignition coil, and spark plug.  Wire the relay similar to how "buzzer" style door bells work, and use it to also toggle power to the primrary coil windings.

Spark plug goes in the tail pipe, wired to the coil's secondaries.
