Strictly speaking a stand alone fuel management system is a processor that controls the fuel aspects of an engine based on the programming and certain engine parameters (mostly MAP or MAF input, throttle position, A/F ratio, among others). A fuel management system only manages the fuel side of things, it does not affect anything else.
Same can be said for a stand along ignition management system, except it controls the ignition system.
When you combine the two, most people usually call them stand alone ECUs or stand alone engine management systems.
Depending on the features, a stand alone engine management system allows the user to alter fuel settings, ignition settings, rev limiter(s), fuel cutoff, and limitless other options.
Some good examples are:
