FORSCAN cruise control programming

[WDWFordGuy]

I was looking at FORSCAN (newbe here) and I saw several options for Cruise Control. The one I'm curious about the the one that says 'Brake Limit 2". Anyone know what this is?

My guess is that it’s related to how hard the adaptive cruise control is allowed to brake. Most if not all adaptive cruise systems limit the system’s braking power so that in case of a software glitch or picking up a vehicle in the exit lane the vehicle is not able to full on panic brake which could cause someone to rear end you.

I actually had a situation in my previous car; was on adaptive cruise and everyone came to a very sudden stop. Even though my car was on adaptive cruise, it gave me the forward collision warning and told me to brake, so I did. Barely stopped short. Looked in the owners manual for that car after and it said something along the lines of “always pay attention to cars around you. In some situations, adaptive cruise may not be able to slow the car fast enough and the driver may need to intervene. Adaptive cruise control can only use about half of the brake systems ability”

I'd tend to agree. I'm not sure if it's brand-specific or simply that the tech has evolved, but the ACC in my wife's 2016 Honda Pilot LOVES to "panic brake". I feel like a fighter pilot when driving it, with my thumb on the cancel button, ready-to-fire the instant someone enters the "follow space" between me and the vehicle ahead. If I fail to do so, it decelerates so aggressively it will literally wake up any sleeping passengers!
