Drove my wife's Regal the last couple days running her to doctor, groceries, and other places, and notice the engine didn't auto-stop anywhere. For some reason, it has decided to behave like a normal car. Don't know what's up, but I like it. Only thing I can think of offhand is that oil says it is at 7% life. Would that keep it out of the stop/start mode? If so, I may just "forget" to reset the service interval when I change oil, and see if it keeps idling nicely.

So today it's back to the usual "shut off just before you stop" behavior that makes smooth stops impossible. 馃槦 Wish I knew what caused it to get better for a couple days, I'd try to duplicate the conditions permanently.

Is that the thing that simulates hood open to put it in service mode? I hear that interferes with remote start.

No, this one attaches to the battery. It does not affect any other system other than the ASS.
I researched this a bit, and it appears to plug into the battery sensor. So do we know how this actually works? Does it lie about the battery's charge status and trick the system into high charge mode? If so, that could greatly reduce battery life. Maybe it's just me being suspicious, but there seems to be a dearth of real information about this "magic" box.

Range Technology says their device will not work on the 4-cylinders, and Trifecta does not list Buick Regal on their website. Buyer beware.

I've been driving it more lately, and think the behavior I experience is probably related to temperature. Temp hasn't been below the magic 41F that I see talked about, but think the formula may be more complex than that, like maybe it looks for large difference between cab and ambient. On the other hand, I don't really care what the car thinks outside temp is and I'm going to adjust the cab to whatever is comfortable for me regardless of what any thermometer says. So where is the ambient temperature sensor located? Might it be possible to fudge it so that the car always thinks it needs high HVAC output?
