Steering Feel & Pull Drift Compensation (PDC)

[mtmtko]

Thank you for sharing the coding for disabling PDC.
I had 4 alignments done and every time the steering was fine for a short time but after a day or so the car was pulling to one side - but not constantly-kinda hard to explain - felt weird.

After disabling PDC the steering felt more direct without the artificial play and the pulling to one side was gone. I drove it a day with PDC off and enabled it after that. Seems like it recalibrates itself after beeing disabled for some time because the steering is perfect again.
According to the ford technician that did the alignment there is no software procedure / no reset that has to be done after an alignment.

Btw: Resetting the longitudinal Sensor in Forscan on the other hand did nothing.

When the Epas with Pdc works I think it’s an amazing system

@mtmtko I was experiencing the same symptoms leading to constant alignments. PDC has been off since I found out how to disable it.

@Marcin38 is working on some exciting hardware/software changes for our steering concerns. Looking forward to hearing more about his developments.

I've been waiting to try this for a few weeks... just did it last night and let me tell ya. The car feels a lot more like I am in control of it and not the all the nanny software. 10/10 recommend

Does this disable the feel of the different steering modes? Is PDC a layer of control on top of the steering modes?

currently adjusting my barton alignment. Then I’ll go test drive it and report back

Steering modes still function correctly!

That's good! Going to try this out the next time I have the laptop connected to the car.

I'm very interested in this. Can you describe the change(s) more?

Is there actual steering feel? Or is there just a change in weight like changing the modes?

do anyone know if this will work on 2015-2017 or is it a facelift thing. I'm tempted to try it.

It works on the 2 gen

I'm going to try my best here - I'm only a couple of days into this but this is my experience so far.

After i installed my suspension and wider tires (see signature - i did it all at once) I noticed only a minor change to how the steering felt. Almost like the computer was compensating for the changes. I noticed additional harshness to the ride but steering lacked a change for the amount of stuff that was changed.

With this disabled - It felt like what i was expecting with changing from base suspension to a solid track focused build. The wheel does get a slight heavier feel to it. My input on the wheel seems to give the car the input I'm expecting and not so much turning a wheel on a racing simulation kind of feel (if that makes sense). When you hit some uneven road surfaces - you will notice the wheel following it rather than correcting it.

Overall you can feel the road surface a lot more in the wheel as well. It doesn't feel like a passenger car now.

Hope that helps

Disabled PDC yesterday, definitely more direct and precise.

You do need to pay more attention on the highway though as it's easier to drift out of a lane.

I haven’t noticed the highway drifting yet. But I’ll keep an eye on it

A small summary for whom is interested in this topic or has the same issue.
The issue: After hitting a curbstone pretty good with the a front wheel - the steering was crooked ( off to the left a bit).
The car got several alignments. Everytime the steering was straight for about a week - after that the steering was off a bit again.

Disabling PDC changes the steering - eliminating the extra torque applied for road conditions - but that was not the Problem.

After adujisting the toe every week or so I decided to get the whole steering rack replaced. Hitting the curbstone must have damaged the rack internaly.

Is there any kind of tutorial for how to navigate through these changes? I have the Bluetooth scanner and forscan program but get lost in the software.

I also have the cables and program on my laptop but can't make heads or tails of any of it.

I find my steering to be extremely precise in the car goes exactly where I want it, but the feel is severely lacking.
