In TunerPro, when viewing MAF table graphs, there are 3 different lines on the graph. The black one shows the data for the bin you are viewing and the gray one is for the "compare" bin data. What does the green line represent? It appears to be close the the black line (current bin data) but deviates here and there. How can it be used for tuning?

 

On mine, V5, I don't have a grey line. It kinda depends how you have the buttons pushed when you open the graph. With none or just the show compare pushed, I get a red and a black. Black is your bin and red is compare. But if I have both pushed then I get a black difference (normally at bottom) It also depends on if you have the show/hide compare button pushed on the graph itself. I have noticed on some bins that the compare is in green. Don't know why.

 

I see what you mean about the compare value vs the compare differance. And possibly the color of the line is based on preferances, but there are 3 distinct lines on my graph. On mine the current bin and this mystery line are very close, but not exactly the same. I am speculating that it may be a "smoothed", filtered or average value. ???

 

Do you perhaps have more than one compare file checked. Each has a color.

 

Bingo!
