Paul,

From what I gathered from the chart you posted the left side or Y axis is the throttle position sensor. I think I have read in the past that these systems are an Alpha "N" strategy, if so that would make sense. More modern Ford systems use load for the Y axis.

The table looks to me to not have enough timing in most areas. Are you sure there are not other schemes in the strategy that adds to and subtract from this table? If there are you need to understand them before changing this table.
