So, this is one thing that has had me concerned, the operation of the exhaust brake, how, why, where, how strong.

Coming from the RAM Cummins, with it's extremely effective exhaust brake, after my 2012 F250 PSD that hardly had any exhaust brake affect, and only passive operation, I was concerned.
And, after the 2020 F250 that I test drove that I could hardly feel the exhaust brake, I was concerned.
From all the reading up on these trucks since the Gen III PowerStroke came out, and the reviews of its operation, I was concerned.

Anyway, from what I read the EB is most affective in the upper rpm range, which all EB's are, higher rpm makes for higher exhaust flow and pressure. Also, what I've read said the brake cuts out when it drops below 1500 rpm, which I didn't like, the RAM Cummins didn't cut off until 1100 rpm.

What I've found today while driving around with the EB on full, is that it seems much more effective than that 2020 I drove, and it also doesn't cut out until the rpm drops below 1300 instead of 1500.
So, I'm thinking that the engineers have been tweaking the operating parameters, making the EB more effective.
Another thing I've noticed is that the EB stays on during key cycles, so long as not too much time has passed between cycles.
On the RAM Cummins, unless you have a trailer connected, every key cycle resets the EB to off. Now, if you have a trailer connected, it never resets on key cycles, but I haven't hooked a trailer to my Ford yet to see if that is the case with it too.

Anyway, I am so used to the way the EB works on the RAM Cummins, I'm very happy with the better EB performance on my 2022 than how it was working on the 2020 I drove.
The super effective EB on my RAM was what allowed the service brakes to last for 500K miles.
Of course, I'm super easy on the brakes anyway, the brakes were still original on my 2012 when I traded it at 214K.

What's anyone else think about the EB?

 

I have a 21 F250 and used the EB for the first time the other day. I have nothing to compare it to except the way the F150's did it.

I noticed it helped slow me down heading down a hill. It also felt like when I took off from a stop it felt and sounded like it was working harder (louder and seemed to take a bit more peddle to get up and go). It did stay set after key cycles which I did like. I turned it back off today and will see if it seems the same on take offs.

It was 95 and humid I was wet from head to toe after pulling drywall off a mobile home without AC. I had the windows open because the AC in the truck would not have cooled off in the 4 miles I had to drive to get home.

 

I towed with my 22 F-350 SRW for the first time this weekend. Our ~9000lb travel trailer. We headed down a decent mountain pass and I was quite pleased with the EB. I'm coming from a 2007 Ram 5.9L Cummins with no EB, so can't compare any other EB experience with the F-350, but I've towed this grade many times with the Ram and would have to use a lot of brakes on the down hill portion to maintain a safe speed. I think I might have touched the brakes on this trip 3 times with the F-350. Wow!

I'm still trying to learn the difference between EB On and EB Automatic modes. I was running with "On" mode for this trip. Without the stereo on, I could hear the turbo vanes changing and the EB apply. It was definitely noticeable. I'd say it waited 2-3 seconds from lifting throttle to when it applied it. It was very smooth.

 

I have a 2019 CCSB and I just got to really use mine last week when I moved from Tennessee to Washington. I was loaded with 1600 pounds of payload, another 1000 lb hitch weight from the flatbed and a 7000 lb flatbed trailer with the wife’s jeep and some of our stuff. Went through 5 passes from Montana to Washington, all with a 5.5-6% grade on the way down. Pulled up the pass at 60 with no issues and the engine brake held me at 60 the whole was down each time in 5th gear at about 2000 rpm. Didn’t have to hit the brakes hardly at all and when I did it was just a little preemptive braking leading into a curve.

As far as the different modes the way I understand it is with the manual mode on you brake to your desired speed and the engine brake will then attempt to hold that speed. In the automatic mode the exhaust brake will activate to maintain the speed set on the cruise control. My experience is that they were in that manner with no issue.

 

Not quite.

The manual mode (first press of the button) won't maintain a speed. It is the most aggressive mode. I see more turbo pressure on the gauge with this mode than the other mode. This mode works best when you're manually running through the gears. At least that's my experience.

The automatic mode (second press of the button, with an "A" showing on the icon) will maintain the speed at which you let off the accelerator. It operates this way without regard to if you have cruise control or tow/haul on.

 

thats great to know! I have noticed in the manual mode I see it much higher on the boost than automatic.
