Question on timing using Accel DFI...

How does the DFI determine timing below 1200RPM? The first column is 800RPM, yet the values I put in are not close to what the timing values read on the computer. How does the computer calculate these values? I just have a need to know

Don't forget about the "IDLESPARK" which constantly changes the idle timing to maintain a smooth idle. Maybe that is why you are seeing a difference.

I thought of that, but I believe even zero'd out, it still varies. Does this happen on anyone elses?
