The AFM Flow table until your fuel trims are close to 0.

Thank you for your suggestion

Civic R18 Calibrations
Can you explain the adjustment in the window ignition retard gear compensation
if I increase or decrease what will happen to fuel and ignition?

You should leave that adjustment alone until after all other tuning is done. In most cases that should never be changed.
