On a 730 ECM what should my idle cell be? I have an aftermarket cam and I need some help with cell boundaries. I understand what the boundary settings do, but have no stock reference to see what part of driving should be in what cell. I idle at about 48kpa. The cam is a 224/230 @.050 in a 350 if that helps.

 

Which ceel is the idle cell will depend upon which mask is being run in the '7730. $88 uses cell 0 as the idle cell. $8D uses cell 4 (typically) as the idle cell.

In $8D the SAM parameters can be changed as to which cell is the idle cell.

In $88 it can't be easily changed. Cell 1 being cruise and cell 2 being decel.

I'm using $8D. My idle cell wonders in to 8 and back to 4. Should I just leave well enough alone with cell boundaries??
