    I don't know about others, but I'd be fine with a somewhat more agressive 'Performance' setting but significantly softer Touring setting. A long time ago, there was a thread debating whether changing the shifter to Sport Mode affected MRC. I don't think it does on my car.

    I would agree. Even though mine is too new for mad tuner's mods that is what I would want.

    I already started driving on AWD touring settings in a non-AWD car and whatever I had left over in there from my last experiments made the AWD settings feel like my old Olds Delta 88 boat. Ha.

    Just so it's clear - are you looking for more of a boat feeling on the highway or is the general issue with how rough you can feel everything when you go over an obstacle such as a pothole?

    Ew. If I wanted a boat I'd buy a Deville. Maybe a little softer in touring would be nice but sport increase in performance I would like.

    My awd isn't as firm as I'd like in the twistes at high speed but when I went from p zero Pirellis to dws continentals I noticed a drastic loss in performance handling as well due to the much softer sidewall

    I would like a Deville DTS F45 CVRSS feeling in touring mode with a sportier performance mode.
    Other wise why bother with user controlled suspension settings if it is hard to tell that you've changed it...

    My comments were more related to lower speeds. The 'slope' of the curve is going to be a very personal decision. Here're my guesses:

    The Performance setting needn't be much less compliant below 30 mph but should become firmer at a greater rate as speed increases.

    The Touring setting is OK at Interstate speeds but below 65 mph should begin softening and by 50 mph & down soft is good. I'd reserve 'boatlike' for 25 mph & down.

    There is no reason why we couldn't have a tank and boat in the same package if that's we wanted, we just have to find some happy mediums. 1BadCadSTS, is that thing finally fixed? I might ask you to help road test some of these settings since you're good at noticing subtle differences.

    PS. I can confirm that the sport shifter mode does nothing to the suspension settings.

    It's reduced but noticeable especially when I run 87 octane (only when I take it on long trips do I run low octane). I found this (link below) and while my ECM has been replaced (the cause of my constant cam position sensor code issue) and has more recent cals in it it leads me to believe the issue is something in what the ECM commands not the TCM lock up commands.

    You know, I think mine does a bit of that too at low speeds while decelerating and it's not even an AWD. I do think it's driveline-related though. The reason why you might see it more with low octane is because your car has less torque then (the ECM will pull timing with lower octane). I don't think the ECM is directly responsible.

    In any case, thanks for the input everyone. I will take all your requests in consideration when I develop the suspension calibrations.

    Echas, the 2005-2009 Jaaaaaag XJ Super V8, with air suspension, is JUST LIKE THIS!

    It's ultra-cushy, until you want to do something, then it firms a LOT before you're done with input from the steering/accelerator/brakes.

    Amazing, really.

    I can confirm today that the AWD has the softest settings of all available, which is consistent with my observation yesterday when I mentioned that my car felt like a boat with the AWD settings after the stiffer settings I had in there prior.

    This is certainly part of the issue.

    I think E described a pretty well touring setting.
    We could give Cadillac its signature ride back being semi floaty in touring mode then go full on tank mode for performance mode.

    Evidently the AWD hardware adds so much stiffness and transmits so much of the road to the driver that it would take a dynamic canceling system to achieve the feel in the RWD models.

    Calling Dr. Bose....

    EChas3,

    I believe you misunderstood. Believe it or not, the AWD has the softest settings of all STS configurations. With that in mind, I don't believe the ESCM has enough of an adjustment range to make you entirely happy, but at least what you have now can be improved.

    I've been doing some more testing over the last few days, including a speed bump and Chicago pothole test and I kept refining my "soft" tune only to realize that my end results are almost identical to the SRX SUV settings...

    At any rate, I will do some testing soon with one of the customers who decided to keep his cable and we'll get a second (unbiased) opinion on this.
