OK, I learned my lesson with snapon bricks and got my carcode cable today. I followed the procedures and get 12 degrees for actual and desired timing. My tdco is about +.09. How do you command it in the negative? I assume that moving the little red dot on the circle and up and down arrow do this. If this is correct and I can't get tdco in - spec I would imagine I need to move the pump. The how to instructions on here are pretty clear on the procedure, just no mention of how you actually command it. As usual thanks in advance. I have no codes and truck runs pretty good. Can't imagine how it will run when tuned better.
