I've got smoke! Digimafam help needed.

I'm running a ZR td with Sdi injectors, 19 psi.



I had a mafam which it smoked a bit, but I put this on my other ZR.



So I brought a digimafam from rover Ron and I've got smoke, like a red arrow.



Smokes on idle and if you put your foot down.



What do all the settings on the digimafam do?
