The fuel adjustment is very similar as an S-afc (that is setup correctly), the only advantage is the timing control (almost).

The way DSMLink handles fuel is not like an AFC at all. With an AFC all you are doing is altering the Hz sent from the MAS to the ECU, which puts it into the wrong load cells, if you have bigger than stock injectors.
With DSMLink you have a global fuel setting, to generally compensate for larger injectors. That changes the injector size value in the ECU, so that you can run big injectors without all the loads getting way out of wack.
Then you have dead time, mostly to help your fuel trims at idle/very low injector pulse width when you have bigger injectors that don't respond as fast. That changes the battery offset/fuel injector deadtime table in the ECU.
Then you have the fuel sliders, which are essentially changing the top half of the ECU's fuel table. They only do anything under higher load/boost, because the ECU only uses the fuel table when it's in open loop.
Then you have the MAF compensation/MAF settings table that you can use to fine tune the MAF during closed loop and open loop operation to get your A/Fs inline at any low to medium-high load situation.
And if you are maxing out your MAF, then you can go into the VE compensation table and then have almost treat the car like an AEM or Motec running boost compensation under extremly high loads.
