vafcII is the one you want, but keep in mind the install is one thing, tuning is another. You don't need a vtec controller until you build up your motor, headers, exhaust, pullies, or your vtec controller wont' really do squat. After you put on those mods (if you plan to mod) THEN you want the vtec controller and tuned

It's more or less pointless with a stock motor

The key is "properly".
With any make and model - tuning is somthing done in a controled and monitored environment like on a dyno with a wideband o2 sensor. Unless you can see your air/fuel ratio and how it's efected by the changes you are making it's all just guess work and seat of the pants dynoing, and that can be dangerous in the hands of an amatuer.
Not to say you shouldn't tune your own car, but be aware that there is much more too it than pressing buttons. The VAFC II is a powerful tool in the right hands, but as mentioned it's a waste of money on a stock vehicle.

i hear with full bolt ons and a Vafc tuned you gain 10+ to the floor off a dyno VAFC II lets you run 2 fueling maps instead of just one, and the increments of Vtec engage points are smaller its something like you can moved the engage point between every 250 rpm instead of just 500 more "fine tune"

there aren't really 2 fuel maps to choose from though. There is just one map setting that is always used, but depending on throttle/vtec engagement it uses a different set of adjustments.
so there is a low throttle and high throttle settings for when the engine is on the low cam lobes (non-vtec), and there is also a high and low throttle settings for when the engine has the vtec cams engaged.
there are really 4 sections where you need to set up the map, but it just depends on the throttle and vtec engagement that depends on which map is used.
I wish there were two fuel maps otherwise i woudl tune one for nitrous and one for NA.
