    Why can't I lock my stall in TUTD mode?

    Hi, I cannot for the life of me figure out why I can't lock my stall while in TUTD mode if my delivered torque goes over 300 ft/lbs.

    I tried hardcoding all non normal tables to lock at a low speed. It works as expected in sport mode, but not in TUTD. As soon as delivered goes past about 305 ft/lbs, it unlocks.

    Could it be the apply ramp rows? I noticed there the last row stops at 310 ft/lbs. Any help is appreciated.

    Tried upping the torque rows in the apply ramp with no luck. This is puzzling.

    I think the problem is that the TUTD tcc tables for wot are missing and it is going into wot mode at 300 ft lbs

    You tried raising your tap up / tap down release speed? It's setup to disengage at 100% throttle - I assume your doing this for tuning?

    I was just sanity testing to see if any settings worked. 2nd was engage at 19 mph and release at 12 mph or less no matter throttle, so as soon as I hit 19 mph it does indeed lock, but I hit 300 ft/lbs and bam unlocked. It goes into WOT mode and that table is not in the editor. 2009+ pcms got rid of the WOT settings and just reference the one table. I don't think there is anything I can do, which is a bummer because I love TUTD for roll ons.
