The numbers in the Link Fuel table represent the percentage of the master fuel pulse width before any compensations are applied.

In a nutshell, larger numbers will add fuel. They have no direct correlation at all to your measured AFR other than the obvious effect that changing the numbers will change the measured AFR.

You can manipulate the numbers in the table to achieve your target AFR by using the equation:

Measured AFR / Desired AFR = Correction Factor

Multiply the current value in your fuel table by the correction factor and this will get your AFR on track.
