Using a typical log of about 8900 records these Histograms are generated.
The X & Y Axis are full customizable, generate any size tables as needed to match your system and use filters to discard outlying data.

RPM vs. MAP vs. AFR

A Histogram that shows what AFR the engine was running at in each of the cells on the table.

RPM vs. MAP vs. (AFR - AFR Target)

Taking that step further, with a log including target AFR, you can set that up as a Z delta field. With a Z Delta Field, then the generated table shows the difference between the Z field and the Z delta, in this case that means a table that represents how far off your engine was running from the target AFR in each cell.

A Histogram that shows what AFR Error was ocurring in each of the cells on the table.
