Easy there, first of all there is no "right" one way to tune, only whats right for you and your particular goal, level and requirements. Its possible that the system you pieced together could have worked well on your civic given different circumstances or some minor alterations or additions who knows, I have a hunch it was a turbo set up and threw in a whole new set of complicated issues to work around that may have warranted a standalone, but its a Moog point here. So many of us are quick to turn our noses up at something if its not conventional, usually based from lack of understanding. I for one have tried convention attempts of doing things only to find the alternatives can work better, so lets not go strait for the eyes just yet 
If someone is willing to be brave and be forth coming about their unconventional set up then lets let them fill us in before we make it difficult for them to do so. The very title of this thread could bring some interesting insight to the subject if allowed.

anyways, heres some things that you open yourself up too:
your a fmu setup. that thing is what 10:1 raio? so at 10psi of boost, your adding 100psi of fuel pressure to the already stock 50psi fuel pressure. 150psi at full boost. pretty high, no matter who you ask, but its the only way you can cheat a 250ishcc oem injector to try and flow like a 550-650, which is what you realy need.
you have a black box to pull timing relative to boost. this box is conervative. and assumes that all setups require the same amount of timing pulled per psi of boost.
then you have a vafc that is always fighting with the stock ecu.
unconventional, yes. working, yes, ideal, no.
if you switched to emu, aem ems, or hondata, you would get more power out of your setup, and eliminate at least one catastrophic failure part, the fmu.
people can run whatever they want to run to accomplish there goal. but there is no denying the increased tuning ablility you gain with other better alternatives.
and whats funny, the money i spent on the fmu, vafc, and msd boost retard i could have bought a used aem ems.
live and learn, hence why this time around, i bought that part first and learned how to use it. 
sorry bout the eyes, was def not intended.

I am not using a black box to control timing, I am however using a Comptech ESM which sol function is to hide boost from the map sensor and its black in color lol.
For detonation control and extra fueling required to run this level I rely on water/meth injection. This allows me to run stock timing map for maximum power without any detonation due to the added cooling and octane associated with the injection kit. I would not be as comfortable trying this configuration on a turbo set up due to the nature of higher heat, inconsistent boost level throughout the rpm range and higher boost early in the rpm
