    help with 2018 Buick "Auto-Stop"

    Hey Tuners,
    I own a 2018 Buick Lacrosse and wondering if anybody figured out how to disable the "Auto-Stop" feature. There are no parameters available in the VCM editor files to turn it on or off like other veh. offer. Has anybody figured how to do this? I would be grateful to know, now (if I can remember) I place the car in neutral right before I stop, but that is a pain sometimes. The 3.6L V6 has a very complicated timing chain set up and every time the engine stops and starts again, it puts "extra" wear on it that wouldn't normally be there for a "normal" veh.

    in testing we were unable to get it to fully disable on these earlier vehicles so we didn't add it to any vehicle we couldn't confirm that it works.
