The Blunami cards don't have smoke chuff input or output. You can get smoke working by putting a small magnet on a wheel (most likely tender), a reed switch next to it, and wiring that reed switch to the chuff input on the 3R/Royz smoke unit. Roy should be able to fix you up with the parts. But that won't accomplish perfectly synchronized smoke and sound.
There were some more in-depth comments on the chuff 'n smoke issue with Blunami on a thread within the past few months.
