the 12:1 fmu normally makes the cars run a bit rich at wot however better rich than lean.

from personal expierience for low boost honda i would use a 10:1.

you just need something tunable to go with it, like an afc

You wont's need the FMU if you get an s-afc or v-afc. This should be in the engine management section.

you can tune a preset fmu or get an adjustable one...just add a bleeder vlave with a check valve on the vacuum line going in so the fmu sees less boost and leans out a little
