Very much doubt I would ever use the Eco mode. Comfort, maybe maybe not. Now here is a question for you BJ. since you installed the last mode software does your car keep the last setting or it defaults back to comfort? The ASS to me its not a big deal, I can click a button and disable it when I start the car. But man if it can remember the last suspension setting that would be reason to do it ASAP.
