    I'm using TunerPro and LS-Droid and have been tuning a couple different P01 and P59 computers with success.

    However, I've enabled Power Enrichment for my 2001 8.1 with 8322 OS, but it will not activate. I see in HPTuners there are two fields that are missing in the 8322 XDF: 2413 Enable Torque % and 2414 Enable Torque % Hysteresis. Is there any way to get these added? I'm guessing these are why PE won't enable, even though I've eliminated the delay and dropped the TPS% enable.

    Any help would be amazing. It kills me to see my wideband at 14.8-15.0 at WOT! Thanks

    I'm in the same boat with an 8.1 on 6125, I'm trying to get PE working, as well as kill off some of the torque cut on shifts and on launch

    Hello,
    I used this XDF to tweak a 0411 ECU with the 8322 OS. Worked ! thanks.
    One thing I cant find is MAP sensor calibration. Linear and offset. (as HP tuners calls them)
