Why not just switch it and see for yourself? I think it's a small difference. No detailed specs.I've had mine in sport mode since day one, just curious how noticeable is the steering difference when not in sport mode? Is there only the 2 steering settings available? Any detailed specs on specific ratio changes?
Here's my take on your long winded input;I have a ton of experience using OBDEleven on the MQB vehicles including data logging to back my assertions vs. "feel"; some of these "performance mods" are 100% placebo.
On the steering - "dynamic" is the same you get with "sport" so you can get this same steering feel if you have 4Motion and by just setting your mode to sport or choosing custom and setting steering to sport so you have this 100% of the time.
Torque limit/starting vibration reduction - in the Atlas this will do zero as it's large and you likely aren't stomping on it from lights; even then, I'd argue this will do little unless you have fwd.
The "increased traction" mod for the Haldex, I saw no difference when I logged it. Your Haldex pump engages based on throttle so as you give it gas, it is engaging. My post #118 with data logs. You can just watch it's activity using "live data" in OBDEleven and see exactly how/when it works. He is simply wrong/doesn't know what he is talking about:
Ahh... I see your point. If you lose traction in a straight line, XDS won't really help transfer power to the wheel that has traction. But it's not pointless. Most of us don't just drive in a straight line. I agree, for the ppl who only drive on the straight line and never make any turns, it...forums.vwvortex.com
The "direct throttle" mod is completely bogus. Only way to achieve what folks think they are getting is a pedal tuner box. My post #79 summarizes the thread but good info throughout include data logs of this setting and using a pedal tuner box. Also good video showing what this change actually does. People thing it works therefore they feel it work - they are pushing the pedal harder:
I did some more thinking on this this morning as I don't have much to do right now w/r to the COVID $hitshow going on. I wondered if you could log the accelerator/throttle %s without the car running which has obvious advantages. Well, you can! Here's a video of how to do it/what it looks...forums.vwvortex.com
When I first changed to the sport mode it was for the change in shifting, which makes a noticeable difference, but I was unaware of the steering being effected. I agree KarstGeo, the change must be small, to the point that I don't sense any change at all after switching out of sport. Maybe I need to try more driving conditions to be sure.Why not just switch it and see for yourself? I think it's a small difference. No detailed specs.
Are you just pulling the shifter back to get the trans into sport mode (which doesn't impact steering) or are you selecting sport mode from the drive mode selector on the center console (4Motion vehicles only)? That adjusts the steering.When I first changed to the sport mode it was for the change in shifting, which makes a noticeable difference, but I was unaware of the steering being effected.

I might have sounded a bit cocky on my previous post and I apologize if I did. I do appreciate you sharing the data that you have meticulously gathered but I still feel it is not providing conclusive evidence as for you to say that these changes are 100% placebo. In fact you kind of confirm in the above post that these changes do in fact make some kind of impact.Long winded? It’s an online forum…if you want short bits, try the Facebook groups.
I suggest that you take the time and read through the two forum posts I linked – the data are there for you with lots of great info based on logging. Based your comments, I don’t think you had a look.
I am fully aware of the differences between the United Haldex tune and ECU flash tunes etc. vs. OBDEleven/VCDS “tweaks”; my 4Motion Sportwagen is tuned and “FBO” as well. No confusion here.
On the steering, yes, I understand that the tweak makes it permanent; I have that setting enabled on my Sportwagen b/c it’s a base model without the modes. On the 4Motion Atlas with driving modes, seems silly to remove the ability to change it with the settings.
On the Haldex, you can log the pump’s activity as well as torque transfer AND time – so you can see all the parameters that this could be impacting. Again, look at the link, I have them side by side, there is no difference. The person in the video makes it sound like there is a delay; you can watch the pump’s activity live and it reacts instantly to your pedal input…more gas, more torque transfer. There are other settings I’ve worked with another person with an R that is heavy into tracking his ride based on the various info available out on the interwebs – lots of those settings in the AWD control unit (both long coding and adaptations) appear to be related to noise and my take is that the settings change the amount of engagement while coasting just based on the wording used…”acoustic”, “suppress anti-droning action”, “anti-impact”, “anti-hum”. I've done lots of launches in my wagon using Dragy so the data are dead-on accurate; zero difference between "increased traction" and stock. My best 0-60 and 1/4 mile times have all been with all the common "performance" VCDS changes in their stock settings.
On the driving profile switchover to direct, controlled over threshold vs. the stock incremental, controlled over time settings, did you watch the YouTube video I linked? It actually shows you live what that does. It changes the time it takes when you switch modes from sport/drive for the steering to change over, that’s it. Why would it also somehow impact the throttle feel permantely? I’ve logged them both w/r to time and accelerator position, and throttle position and thrown up what a pedal tuner box does – this is doing nothing. If I did a blind test I bet there would be no correlation OR I could get the same feeling response by the driver by just telling them I made a change to give it a more direct/linear feeling but change nothing. How can a pedal box be able to clearly show what it is changing w/r to throttle feel (more switch output for the same amount of pedal input vs. stock) in my logs but this change doesn't? You literally log the physical position of the pedal and the electrical output of the accelerator switch...what else could it be changing? I even logged driver torque demand for some. All in that thread.
The other interesting things with the Haldex and “driving profile switchover” aka “direct throttle” tweaks are that if you spend the time, like lots of time, reading the forums, FB groups, etc. you get all sorts of different descriptions of what these do based on feel/butt dyno. How is that possible? They should only do one thing and it should be the same for everyone, like an ECU tune adding power. It’s b/c it’s completely subjective with no data and just based on folks thinking they are doing XYZ when in fact nobody knows exactly what some of these are doing and folks just keep passing these around without questioning them.
The beauty of science/testing is that it doesn’t rely on someone’s subjective feelings about changes.
Lots of Googling for "OBDEleven". Just a tool that allows you to make changes to your VWs systems for small things like lighting etc. Lots of fun and some of the changes are v. useful. I've got a master list stickied I think somewhere here. The Atlas FB groups are good as well, I've posted a lot of useful info there. There are some nice YouTube videos by shopdap.com that go into a bit of detail on what all this is. Finally, the Atlas forum on vwvortex has info. This is DIY-ville so you'll need to put in the time to learn.I don't understand any of this !
That is a popular change you can make, I can only confirm that the change that is commonly shown online to do this works on the 2018s, not sure about the newer models. Easier to just get used to it...that's what I did, doesn't bother me a bit and quite frankly, I like the quiet at stop lights.But I'd sure like to permanently eliminate that stupid Auto Engine Shut Off !!!
