I'm having a difficult time understanding why column 8 is asking for additional fuel, while parts of column 9 want less fuel. If I adjust the fuel to match the overlay, I'm going to have intersecting lines.

What have I done wrong?

Average the two fuel ratios. If one column is 12.7 and the next column is 13.5 youll need to remove 4-5% from one column and add 3% to the next. So either add or subtract your average. Most likely the column that is giving a rich/lean reading in comparison to its opposite value in the same rpm index one column up is barely being utilized and is providing false readings.

If any motor im tuning is giving a lean reading in a higher column at WOT and a rich reading in the previous column, Ill add fuel since most of the time spent will be at the map pressure where the car was lean. You may pm me if you'd like any further assistance.
