Automobilista 2 Custom Force Feedback - Overview & Recommendations

It might need a separate scale for in file levelling

so you could add a scale in form of
(abs_scale 1.0)
And place in appropriate section of scales at top of file .

then post the calculation section but before the fx output , you could add a extra mod.

In form of
(abs_effect (* abs_effect abs_scale ))

numbers are just an example and this is a simplified method, it may need more nuance.

edit : now that i’m back home and have tested.

The above works fine and was able to implement into file quite easily.

it works well and feels exactly like i expected..

only thing for me personally is that it’s not something i particularly enjoy, as it does what i expected and interrupts the feel of the tire and grip at a important point and also tends to still activate mid corner even when off the brake , such is the way the abs seems to work .

Ultimately my preference is to not have this effect come in through the wheel, and is best suited to pedal haptics for those that have them, but i think simhub caters to that already..

but if it’s something you want it’s nicely done by JP and easy to implement.

 

I'm not even that big of a fan of it on the pedals, and I have a mqb1 direct mounted to my brake pedal. I find it distracting and would rather focus on filtered loaded slip haptics as a driving aid

 

I have ABS on the brake pedal (Simagic Haptic Reactor) and also on the motion platform so it makes more sense for me personally. In addition, it distracts me to feel it in the wheel and it overshadows important information from other FFB. But for people who like it, it's definitely a good thing

 

Well, I put the lines where I think you meant them to go, and at least it works. The reason I wanted to use it, is because I don't have any form of haptics on the pedals, and it is a good indicator to me. As strange as this may sound, when I get the ABS effect through the wheel, my brain tells me it is my foot receiving the effect. So it works well for me. Thanks @Kuku Maddog and @Joaquim Pereira.

 

I have P1000 pedals and, maybe, I'll add haptic feeback later on. Since I don't usually race cars with ABS and Simagic Haptic Pedals Reactor is, well... not very eye catching (like... a real car doesn't have a thing attached to the pedals), ABS on the wheel will do for the moment.
Thinking about it....perhaps I'll had a small shaker under the pedals and use my P1000 to run it (advantages of been an handyman )

The ABS effect tells me I've already surpass my luck in that turn, no need for further info .
And yes, I also find the ABS acts too early in AMS2 and a very small tap on the break will activate it mid corner (confirmed by SimHub and AMS2's shared memory telemetry).
I usually use ABS turned off, ABS=1 and, in rainny conditions, perhaps ABS=2.

Not strange at all, I do feel ABS effect more on the rig (pedals and seat) than on the wheel itself (same for engine revving up/down when standing still and holding the wheel - if not holding the wheel, no rig vibrations at all).

 

I just loaded this up and WOW! This completely changed my AMS2 experience 1,000%. Thank you so much for taking the time to do this and post for others.

 

Although your file is not completely to my taste, I have to commend the fact that you are pushing the custom file to do new and interesting things.

 

Thanks. I've yet to achieve all the goals I was looking for, but I'll keep trying the best I can .

 

How can the straight line oscillations be reduced? Min force in file and in game already on 0

 

I'll post a new version with (vastly) revised front suspension algorithm.
A small change with big impacts (à la Reiza ).

Keep in mind, unless proved wrong (I wish!!), I believe the FFB feedback loop (via USB, like we have on home PC) will never be stable enough for a high speed transition system. That can only be achieved with a local control loop in a dedicated system (the wheelbase electronics must be the only ones responsible for that stability, which is not the case).
The alternative is to tame down FFB forces around the center or slow down (low pass filtering) fast FFB signals (I won't go that way ).

 

Use default, no default plus, added ndp 5, nfr 3, nin 5 in your fanalab setup.
I use a DD2 and zero oscillations with that setup. If I use default plus have terrible oscillations and can be very dangereous for my hands.

 

I'm on rFuktor 5.0.1.3 and the oscillations used to be really bad, especially in braking zones.
I love that profile, but at some point I switched out rims for a BMW gt2(v1, very heavy has vibration motors that you can set up to spin at wheel lock or something).
Turns out that was enough mass to dampen out those oscillations to the point where it's barely a thing.
I'm on a 8nm csl DD, so more potent bases will ultimately overpower that too.
Seems my favorite ffb profiles always have an oscillation issue, like it's the price I pay or something.
My point is, If you can get your hands on a heavy rim, it might mitigate that stuff more effectively than you thought at first.
C if you can maybe find one 2nd hand.

 

thx for your work, your FFB file was a complete game changer for me! Finally enjoyable. You should have a sticky and prominent thread here not buried in hundreds of posts

oszillations are the only negative point

 

I have to say that with v10 of Joaquims FFB file, i don't have much of a problem with oscillations anymore. Oscillations were much more pronounced with v8 and prior. I think v10 is a great improvment.

 

that may depend on base? i cannot let go of the wheel, its going wild. i use fanatec recommended settings and joaquims strength recommendation. damping up or down is doing nothing

 

FullFFB - New Version​

What's new:

• Substantially revised front axel algorithm (better tracking, better weight transfer feeling)
• Substantially revised rear axel algorithm (to mimic rF2's manners)
• No more pseudo-gyro forces (rack forces already capture that very well)
• Several adjustments (including removed excessive oscillations)
• (please, read the notes - very important to achieve more pleasure and less pain...)

Still to improve/implement:

• (no roadmap)

 

While I had actually planned to put my G25 aside for a while I spent some time trying your latest file today. WOW is all I can say. It works well out of the box without the need to modify any settings in the file itself - after playing with the ingame settings I settled for 65/15/30/0, which seems to work great on most cars. Some require tweaking the per-car gain modifier by +/- 1-3 percent, but that's it.

Also, after playing the Beta the other day (where I still use Default+) I was pondering what the major differences between the stock FFB and your file are. To put it simply, the default FFB of AMS2 lets you know what that the car is doing, particularly with regards to the rear and its overall momentum. Your file on the other hand doesn't just let me know what the car is doing, but helps me make the car do what I want it to do! Simply put, it makes it easier to be precise and inspires more confidence, though the degree varies from car to car (but that's more related to the cars themselves rather than the FFB). For example, I just tried the Porsche 963 LMDh today using your latest file and holy smokes, the feedback is among the best I have ever experienced in any sim for such a car!

I'll leave it at that for now as I probably won't be spending much if any time behind the wheel for a while. Major kudos to you for your continued work on the FFB, it is greatly appreciated.

 

Like I already mention in private message, I like this version a lot. Didn't have time to try it out with more than couple of cars doing couple of races, but it's really good just based on those alone and clearly the best version of yours I have tried out this far.

(the v10 that came before felt very different, so even if that wasn't your thing, I encourage to give this one a try too).

 

amazing work man! my new fav ffb. For my taste I just removed engine and abs vibes, kept everything else as is. Using linear for ffb scale on my wb is not something I ever do, but works very well with your custom, peak certainly feels wrong

 

It was called to my attention by @GFoyle that v10 Gen1 was producing (very) low frequency oscillations in Barcelona's main straight.
I tested that combo and was able to reduced to insignificant levels using the changes below. @GFoyle confirmed the same results.
Because of different suspensions geometries/forces, this could be used/needed for some cars. As posted here, I've done most of my tests with McLaren 720s GT3 (the rational: if 'dull' cars can feel good, so will all the others ) . Also tested LMDh Porsche and DPi that felt both very strong as this v11 puts much more forces in the middle range (the overall forces will feel much stronger).

Here's the FFB histogram in Barcelona main straight (almost a Normal/Gaussian Distribution):


_______________________________________________________________________________________
To reduce forces related to weight transfers, try this...
Replace:
(rack_damp damping_slider) # damping [0-1]
with:
(rack_damp 0) # damping [0-1] #was damping_slider

and replace:
(rack_coarse_lfb (+ rack_coarse_lfb (* wt_factor adhesion_front_scaled)))
with:
(rack_coarse_lfb (+ rack_coarse_lfb (* wt_factor damping_slider adhesion_front_scaled)))

Now, put damping slider at 70 and vehicle-specific gain at 100%. There you have it!
Adjust the damping slider at will, it no longer represents damping but forces from front suspension.

The need for addicional FFB sliders kicks in once again...
