    Crazy rich Commanded AFR after 2bar conversion--Any thoughts

    After converting a tune to 2bar SD OS I am getting crazy rich commanded AFRs. I have searched all over the tune looking for the multiplier causing this. Any ideas on what I am missing?

    reapply & rewrite entire the custom os using 2.22...you likely applied the custom os with an old bersion that had a boost enrichment bug.
    It doesn't have to be perfect, it just needs to be done in two weeks...

    I am using version 2.22.3152.18236 and it was the version that both tunes were written with. I recreated the 2bar tune again from the original tune just incase and had the same results.

    I thought it would be the bad version, but you changed that.

    What is the unsupported parameter that your logging? I don't know if that has anything to do with it or not.

    205% IDC that's not good.

    That is not correct either. The car has Motron 60lbers and a Walboro 255lph so I know they are not maxed out.

    email support your stock file and the one giving you the issue but I'm pretty sure this was fixed long ago.

    What's up with your min TPS being 11%? It must read 0 at 0. It looks like it flutters after your pull too.

    It's what happens when you copy and paste bad data... You get that point where commanded fueling moves from 14.6x to 11.X and the wideband doesn't reflect the change for 2-4 frames. Now for 2-4 frames you get crazy false lean error (bad data!). If you don't see it for what it is and you just copy the whole log off and paste it, this is what ya get.

    Exactly. The table is stupid fat. Made no sense to smooth it out when I knwe that the table was no good.
