    When I switched to a s256 about a year ago, I had to add a lot of fuel using the fuel sliders, a few months ago someone on here suggested zeroing them out and use mafcomp, which worked great and I was able to get a more accurate afr at wot, but mafcomp is extremely high to compensate, which I don't mind to much except my load factor now goes up to 320/340ish, and when I increase the boost to 22 for one pull, it went to 370...which is not even on the dsmlink table.
    Another thing is that dsmlink thinks I'm running like 38psi.
    This wouldn't bug me to much, but I have meth coming in and when the failsafe activates I would like to have lower timing on that part of the table, so I really just need an accurate load factor.
    Any help is appreciated. Thanks

    *lower timing on the lower part of the table.
    My failsafe will bring the boost to 15.5, which hopefully will lower the load factor enough so I can have much lower timing there.

    Isn't there a way to make a global MAF adjustment and then even it back out with the global fuel setting?

    What is your AirflowPerRev at idle? Attach a log so we dont have to guess about what your settings are...

    Working on it, I'll upload a good pull, then the one with 370 load, I had to let off pretty quickly on that one because of knock (6 degrees of retard)

    i have lowered the boost since the first pull, the second is mostly for my current settings.

    AirFlowPerRev at idle is 26-28. not sure it matters but i have switched to locked open loop, but that shouldn't affect this problem.
