Try changing the oil???

some black smoke is ok when you VTEC is coz that is the car trying to protect itself at the high RPM

my car does that too.. running rich is better then lean ... i guess if its not too much its ok

got a mate who was blow black smoke, till he changed different petrol station and it stopped.
i guess thats one option you can try.

you could try running half a tank of an ethanol based petrol to see if that leans it out a bit and cleans up your lines a bit. aside from that, the only things you can do to lean it out is tweak the ecu, or bump up your intake flow rate.

if ur talking abt the one shell has...
i m strongly against it... b16a2 is not designed to run on it....

errr okay then..

black smoke could be caused from carbon build up in your cat. then when you rip it, all out it comes

the ecu from the factory is tuned to run rich at higher rpms to protect the motor... increasing the intake flow rate, or the amount of air coming in throuhg a free-er flowing intake will cause the ecu to run more fuel is my understanding... could be wrong through
