Determine which cell to adjust that is being traced????

Post by ITR 1102 »

I know the basic concepts already. Really, the only thing that I have not found a clear explaination on is which cells to change while tuning partial throttle. Here is an example.

Say I need to start fresh and tune all the load columns.
I do idle first... Most of the time it is idling in colums 1/2, and sometimes 2/3.

Anyway, when the cells are being traced, there are 4 which are shown in red... To adjust the air / fuel, do you select all four of the cells and adjust them all, or do you adjust only one of them. I ask this because as you move to higher manifold pressures to adjust, if you had adjusted all four cells previously, you would once again be changing 2 of those same cells for the next load range. Can someone help me with this please?

For example: Say that while while datalogging, the 4 cells below are highlighted. Do I make changes only to one cell, or select them all? I will need to make changes to the whole map, and will be tuning for boost as well. I just need to clarify the order of making adjustments to the cells.

It is mainly reading from the upper left cell, and is interpolating from the others. It is best to only modify one cell at a time or entire rows to keep things smooth.
