I'm looking at something for a management unit. i'd like window switch operation, as well as the ability to retard the timing some for bigger shots. the zex control unit looks good, but is there anything else, or how much can i get one of those units for? I need something that is relatively inexpensive yet pretty effective. I'd get the whole zex kit, but i'd prefer to piece a kit together with the parts i want to use. i already have an nx bottle and guage, i'd i'd like to do the lines myself, as well as the wiring. I'm just looking for a good control unit. thanks

 

If you just need a timing retard and window switch, the Mallory 685 ignition box has both as built-in features.

 

i love the zex thing.. adjusts fuel and timing? anyone know much about those?
