WOT compensation tables and knock control related tables

Post by impc »

Hi,

1. It's nice to have option to change WOT compensation tables, but can someone explain in more details how it's working? For ex. how is value defined in table used for final fuel amount computation? simple formula would be great!

2. Knock control related tables use 10 columns, for ex. if i'm using all possible columns (16), custom rpm/load indices for NA application, then it's using column 10 values all the time when MAP is over 600mbar (column 10 is 600mbar, column 16 is 1070mbar). Is it correct that in this kind of setup it's near impossible to use knock control?
Also it's unclear, how K.Limit value is calculated, check screenshot.

Also K.Retard should be 9 degrees instead of 7 if K.Control is at 75% and knock retard table contains 12 degrees?

Thanks!
