   Noticed this when replacing some vacuum lines with silicone hose,my experience with these tells me on a normal ecu these knobs are for adjusting fuel trim,in this case its only for ignition ?,is it there to change timing due to adjustment of this this rotary knob.
   Any help would be appreciated TIA.
