I never had that trouble when I put one on my Rover though
p.s how do I reset the ECU

TBH not too sure why you are just getting the black smoke

to reset your ecu disconnect your battery ideally over night, then re connect it, just make sure you know your stereo code
If you still get the black smoke put your standard filter box back on to check to see if you still get the smoke
