So I set my BlueCruise tolerance to 15mph over speed limit. I thought I'd read on here that it wouldn't work above the tolerance and I didn't want it turning off going 76 on highway.

I've now noticed it is randomly adjusting my speed to fit this tolerance. I set it for 78mph and then 10 minutes later when the speed limit went from 65 to 70, I looked down and I'm going 85!

Today, I set it back to 10mph tolerance. I'm cruising at 78mph and when speed limit goes from 70 to 65 it automatically reduced my speed to 75. I do not like that at all.

How can I get this to not change my speeds? Turn the tolerance off completely?

I do not think that is random. The tolerance amount of x mph will apply whether you are going 30 or 70. Either turn off the tolerance or the speed limit sign recognition. I have mine set at 7 mph, If I am going less than 50 I manually bump it down 2 or 3 mph. It will go back to 7 when the speed limit changes (either going up or down).

My 2¢

I have the automatic speed adjustment turned off. My speed choice is too situation dependent to leave it to a one-speed-fits all calculation. I might set the cruise to 77 on a 70 mph highway but 60 is more comfortable on a 55 mph road. It's easy enough to adjust speed using the up and down buttons to set the exact perfect speed for a given situation.

I have played with the tolerance as well, and do not like the way this is set up. The worst part for me is that speed limit sign recognition is required to use Blue Cruise, and I have take the truck on several very long trips. The inaccuracy of speed limit recognition technology also contributes to this "adventure", when a sign that says 55 mph for truck towing trailers causes my truck to hit the brakes from the 70-ish I have set, all the way down to 55, even though it doesn't apply to me. Basically, if the system sees a rectangular sign with some large numbers on it, it "reads" that as the new speed limit and changes your speed. This is going to need to change....

So I read the little info buttons and found that the speed limit sign recognition is specifically about adjusting your speed to your tolerance. So I deactivated that and my blue cruise will stay where I set it now.
