Open Loop WB PE Table correction with Maths

[f.creek-ranch]

Its a pain to correct the PE table with the FA enrichment rate to get the right AFR.

EQ Error isnt a help, so I try to use a lambda of 12.4 instead of the commanded EQ vs WB.

Best option would be to use a fixed FA (0,0806) instead of the AFR and get the difference from the WB, which has to be even in FA value.

In this way we would get the correction in FA for the PE table.

I know there is an excel table in the forum to convert EQ, but Im not confirm with excel.

Any suggestion ?

This is how I go about making adjustments to my PE table. Using values from the O2 (AFR) graph in vcm scanner.
1 divided by Desired AFR minus 1 divided by AFR shown in cell from O2(afr) graph equals total positive or negative change of FA for PE to achieve desired AFR for that cell.

1/ Desired AFR - 1/ AFR showing in the cell you are adjusting = Total amount of FA needed to be added or subtracted (if answer is negative) in PE for desired FA.

I will try this out, thank you.
