2022 CCD shocks ride like crap?

[tbinmd]

I wish Ford would allow seperate CCD suspension settings rather then grouped into the drive mode. Make it like the Raptor. I want the normal drive mode with sport suspension setting.

157" KingRanch Powerboost Max Tow with CCD

Came with the Pirelli's (20") and I run them at 32PSI cold.

Added RAS to the rear suspension and adjusted them to less than the 1mm spacer setting that they recommend for carrying weight, but I am using them to "tame" the rear end over bumpy roads. Helped tremendously.

However, I was very disappointed in how conservative Ford tuned the CCD, especially in Normal mode. There's so much potential in active damping, but not giving the driver access to settings was heartbreaking.

So I've been messing with the VDM module and currently it's starting to make me finally smile with CCD!

I've edited the properties with Forscan related to unsprung weight. Basically I have increased the value by 20% and the result is the real-time algorithm seems to have upped the damping to compensate. The best way that I can describe the difference is it dulled the sharp edges of road bumps and potholes. It's muted. It's lovely, actually.

I have more experimenting to do, but first I need to address keeping the truck flatter with some rear Antisway bars. (and the front oem sway bar isn't anything to write home about)

I don't want to try to use damping to keep the truck from body-roll. And if I did try to use damping to limit body roll the damping then wouldn't match up with the oem spring rates.

Anyways, if you aren't feint of heart, here's the settings that I altered:
Everything that was 750Kg, I changed to 900Kg (20% increase)
And what was 525Kg, I changed to 625Kg
(just short of 20%)

I had zero issues with DTC's

I'm stubbornly dedicated to seeing if I can get this CCD feature dialed in. I LOVE the technology behind it and the price is an outright bargain. But if I can't get the truck to handle the way I want it to, I WILL yank it all out and return to Fox 2.5 DSC, or something similar.

It's possible for an F150 to ride and handle fantastic for a truck. I've accomplished it before. We'll see if this CCD can be dialed in.

I am putting this on the list. Should have the truck soon and once I get a few miles on it I’ll give those settings a try. Surprised that the baseline weights are so high. I have the 145” WB and my module listing has the same weights as yours initially had. Keep up the good work!

I too was a little confused by the descriptions VS the AsBuilt values that came with the truck. The redundancy across different descriptions is confusing too.
But I also don't have a CLUE how those Forscan gurus figure out how to map a module like the VDM? It's amazing.
I would love to find a source for more clarification on field labeling.

If you look at the last record, it's called "Front Wheel Rate", and it's measured in Newtons per millimeter. The value of 30 = 171lbs per inch.
I got really excited when I saw that record because THAT'S a legitimate suspension tuning value. It's effectively the spring rate of the front suspension, but measured at the center of the wheel instead of the spring itself. (which is probably something like 600-650lbs/inch on our F150. The FWR is a lower value because of the leverage the wheel has over that spring as a result of the control arm)

Anyways, the reason that was exciting is that in theory you would only have to change that value and it's likely the software would respond accordingly and predictably.
The problem, and MYSTERY, is that there's no entry in the VDM for the Rear Wheel Rate???


Here's a cool article on Wheel Rate.

@Snakebitten, how do the factory drive mode settings affect CCD behavior? Is Sport mode "tighter" than Normal? Does Tow/Haul raise the rear when weight is added to bed or rear bumper (trailer tongue weight)?

Just curious and figured you may know!

If you monitor the PIDs for the VDM module you will see the various values change when you switch modes.
I'm not saying I actually have sorted out what the values actually mean ? yet, but it's starting to make some basic sense.

There's too many pids to populate the gauge screen with so I just loaded the front left corner pids.
Here's what they look like:

Yea, ALL that is just for one damper. ?

But honestly, I think I could narrow it down to just the ones I have circled.

When you switch from say Normal mode to Sport Mode the most obvious value change is "damper current Amps". It switches from a static .6A to .7A
It appears that the circuitry that controls the damping valve(?) operates at very precise micro-voltage? (Afterall, it IS a common 5Volt computer module)
For example if you apply normal brake pressure, you may not see the amperage increase, but if you apply enough brake pressure to introduce nose dive, the amperage increases. Thus increasing the damping (resistance to compress)

The VDM_LF_D_PRLL_RES_G in mOhms pid is the one I really want to know more about. It's by far the most active, electronically speaking, and it's the one that varies the greatest between driver modes. It operates very fluidly within a range, and the range changes dramatically between say Normal VS Sport.
I've just gotten started with the AsBuilt edits to the VDM module, but I believe the correlation that I am looking for is the AsBuilt values relationship to VDM_LF_D_PRLL_RES_G

There's gotta be some fellas that understand this stuff way more than this old man just poking buttons to see what happens. ?
Although I admit to being hopelessly fascinated.

Oh, as far as the truck raising its own height if a load is put on it? It's not that kind of active suspension. I don't think it's possible to adjust height without an air suspension component. This is a very basic active damping approach. Basically it's only capable of variable "resistance" to compression/rebound.

Amazing, thank you!

I have an iPhone and use the OBDLink app with my MX+. I was making new dashboards and display last night but couldn't quite duplicate what you have to hybrid battery current, voltage, and SOC. Are you using the same app for your displays? If so, can you share your settings for the gauges?

 

[Snakebitten]

I have attached my exported gauges and the user-defined OAR pid.
Note that the forum only allows certain file types to be uploaded, so I changed the extension of the file to pdf.
You will need to change it back to stg?

Also, the gauges may not "scale" perfectly on your device because of differences in the resolution between devices. I have the gauges highly customized on that one dashboard that is my primary for driving. They are nested tightly together with overlap, so you might have to "drag & move" some of them slightly?

 

[Snakebitten]

If anything I think my CCD is a touch floaty when not in sport mode. But def rides nice.

I agree.
If you want to experience just how much of that float the CCD system is capable of getting rid of? Just unplug the driver's side shock absorber!

It's eye opening.

The way the system is designed is IF there is any fault detected in any of the 4 corners, the VDM module will default to analog shock absorbers. And on CCD, unlike the Raptor, it defaults to full stiffness, rather than full softness.

I think you will be amazed at the range that these dampers are capable of operating in. I don't know why Ford has them programmed to be so soft, regardless of the drive mode selected. I haven't found any way of manipulating the system to be even close to what they are as analog dampers.

As I stated, the easiest to unplug is the drivers side rear. Here it is unplugged:

You will get an instrument panel warning as a result, but it clears itself when you plug it back in after one key cycle.

In analog mode the body roll side to side vanishes. And the front-rear pogo under aggressive braking is gone. So these "soft underdamped" (my opinion) shocks are being manipulated intentionally to be that way. Arghhhh

This is another reason why I personally believe that the truck will prosper immensely from a rear Antisway bar, and maybe even a heavier duty one up front to replace the anemic one from the factory.
I predict those changes will enhance the softer damping that Ford has programmed into the CCD logic. You might get your cake and eat it too?

Body control vastly improved with anti-sway forces in play, yet still having compliant damping for a nice ride on road irregularities. Or put another way, the lack of body control is exacerbating the soft damping?

Snake: what rear sway bar did you install? My boat is no problem, but it might be helpful when pulling my horse trailer.

I actually haven't yet. That's why I want to hold off on dialing the damping in further until I get the Antisway addressed first.

I had Helwig front & rear on my 2018 KingRanch Ecoboost. It was transforming!
I ended up backing off on the high speed and low speed damper settings on the Fox 2.5 DSC dials. No longer did I need to burden the damping rate to keep the truck flat.

I would already have rear Antisway on this Powerboost if I could have gotten an answer from Helwig (via Stage3) that the bar they had in stock fit the Powerboost too. But they sold out before I could get a response. (and I still don't know. Does anyone have a rear Antisway bar on their Powerboost? Any brand? I want one!)

Hey so I’ve got a 2022 Lariat powerboost, long wheel base with about 4000 miles on it. Has anyone with the CCD shacks felt that the ride of the truck was harsh and bouncy? We test drove 2 short bed Supercrew trucks before we ordered and I remember thinking how smooth the ride was. Those did not have the CCD shocks. From day 1 my truck is rough over bumps and and seems to almost shutter on bigger ones. Not even close to how the test trucks rode.

I’m wondering if the wheelbase has a little to do with it. Almost seems like the electronic control of the shocks isn’t active at all or something, like they never activated them at the the factory or dealer.??‍ Anyway, I’m open to any comments from people with expletive with these shocks. Thanks!

It's a heavy truck, with a solid rear axle, a crude rear suspension, and heavy rear leaf springs. That's pretty much whatcha get.

 

[Snakebitten]

Are you saying that a solid rear axle truck can't ride substantially better than they come equipped oem?

Of course I don't think that's really what you mean.

Did you get an answer to your question from Helwig? What did you end up doing? I put an anti sway bar on my Dodge Dakota many years ago, and I'm not sure I ever noticed a difference. Do they make a noticeable difference on an F150?
