Automobilista 2 Custom Force Feedback - Overview & Recommendations

Nice work @Stakanov .
i didn’t have time to test with tightening, but i inserted it into my current tune , which i’m quite happy with centering. i was able to run a couple of laps with both the lotus 79 and ginetta cup car and it felt very good and intuitive. with clean and fast response.

I was able to drive with the throttle very nicely and was noticeably inducing less oversteer in early part of corner due to feeling it earlier.
so generally driving tidier with more accurate control.

 

I have not tested these values on my steering wheel ... from your previous judgment I only imagined that the T300 has a lower tendency to the elastic effect compared to my G920 (which skidding and counter-steering, tends more to toss you first to one side and then on the other) ... so I only applied graphically for the T300 what I did on mine but in a reduced way ... the curves on the G920 are very similar in shape especially in the "Start" position but then much wider, extended and with higher coefficients in the OS ...

Karsten's curves are NOT wrong in fact they are very correct but I think they are calibrated for HighEND steering wheels and especially for DDs ... if you notice the graphic shapes start concave and then have a hint of convexity before aligning, in the OS below the theoretical line 1: 1 and in the DS above the theoretical line 1: 1 ... it is precisely the different attitude and the different forces that a DD steering wheel has between the central position and the transition to the curve with consequent OS or DS ... difference necessity!!

The low end, on the other hand, is an elastic potential both in the center and in the curve and when it starts with the OS or the US, it needs a lesser but wider and deeper relaxation and therefore always below the 1:1 line ...
ALWAYS IF I INTERPRET THE GRAPH AND MATHEMATICS CORRECTLY ... MY LIMIT IS NOT BEING ABLE TO READ THE INSTRUCTIONS AND THE LANGUAGE WITH WHICH THE FILE IS COMPOSED AND SO I GO TO INTUIT!!!

Anyway @Kuku Maddog , i am very pleased that you like the first impression. If you have any dissatisfaction, you can always play with the tightening, with the GAIN, with the LFB and the DP to find your taste.

 

So theoretical question for you, guys. When the 5-8N.m CSL DD wheelbase comes out, would you use a top tier file because it is tuned for the speed of DDs or the mid file because it might be in better tune for the forces? Asking for future downloads xD

 

t

the file now is generally one size fits all. just minor tweaks for preference. with the most extreme being for the logitech . that new base should be fine with it as it is similar strength to thrustmaster and will just have more fidelity.
it should be fine as karsten uses a DD wheel and it clearly works for him.

 

Woohoo. Cheers for the reply.

 

@Karsten Hvidberg @Shadak @Panos Schoino @Renato Simioni

I’ve been reading some of the comments on youtube in response to @steelreserv ’s excellent rebuttal video.
There really seems to be a huge following for the custom files , perhaps more than i imagined.
many people have said it’s made the sim for them , so you should be super proud. ( maybe you should have made it donation based )

I also see a lot of people have maybe been overwhelmed by the huge thread and so so many different posts and files and have not been able to get there head around it.

It can take a lot of reading to get familiar with the lingo and values if you enter the project later. I had a similar experience when trying to figure out pc2 originally when there was really just jack spades files. It was a forum all on its own.

This thread has become that. And while the work that been put in over the year is all incredibly valuable, I feel that rFuktor has surpassed all before and maybe its time now to begin a new thread dedicated to rFuktor and beyond.

I feel now is the right time ,as i believe there’s going to be a influx of interest from people new to Ams2 .

So the simplest way to present the option of custom FFB may be the less difficult for them and you.

 

I made a few edits to the 3.5 experimental, here is the result.

* Custom spring for tyre deform, fixes the rain issue completely.
* Adjusted slip feel.
* Adjusted karts slightly.

New custom spring values "tyre_deform_stiff" & "tyre_deform_damping".
I think adjusting these harder might make sense for belts at least.

Is it any better/worse for you guys? Or was the prior version just as good?

 

Hello
The previous version 3.5 exp was better for me, the center was harder with a better feeling of the tires.
based on fanatec csw 2.5

 

have had a wee play with it after transfer of my tune values.
hard to pin point what i’m feeling. had lot of stationary ( not rolling) resistance and micro vibes going on with your starting deform values.
Did feel lighter overall.
I turned or stiffened it to 2.0 and equally 2.0 damper and it reduced the stationary vibes and gave more strength to rolling feel.

i’m struggling to tell if it’s better or worse over previous. but it definitely different.
I need to play around more but also aren’t sure what to expect from each change without some reference.

 

Ok, so will stick to the last good 3.5 exp as the final 3.5
The other stuff will be for 3.6.

This means your edits have all been made for the final 3.5, making it simpler for us all.

Here is that file again, just so it's easy to find.

Attached final "rFuktor 3.5".
Also attached "rFuktor 3.6 - Experimental".

Experimental 3.6 tries to improve the issues of the latest 3.5 experimental, based on comments from @Kuku Maddog @LE GAULOIS .

 

First impressions feels good with only a few minor prerequisites scales changed before test.
Didn’t change anything in the relax curve like recent experiment , but it feels nice.

 

Just did a back to back test with stock os and us relax curve and experimental @Stakanov inspired values.

I think the wheel feels more natural and full with stock values and allows more leeway in catching slide. ( basically lets me drive like Jeremy Clarkson if I so desire.)

alternative values give more mid corner throttle steering feelings, but is a little lite on entry signal of turn in and is maybe a little harder to correct excess oversteer.

maybe something in the middle might be better, but I have absolutely no idea how to read the curve and what I’m trying to make the line do ?

 

Try this....

(relax_os_line2_start_y -0.0022)
(relax_os_pos 0.010)
(relax_os_width 0.0600)
(relax_os_coef -0.010) or (relax_os_coef -0.015)

EDIT: Don't consider the curves I thought you were talking about the final 3.5 or better if you want to try them do it on that file maybe add something on your T300 ... I'm now seeing the 3.6 EXP but I find there is something strange and I lose control of the rear .... but I'm just starting out

 

version 3.6 exp.
Feeling of too much lightness when stationary, oscillation
high speed flywheel

 

How do you like the grip loss feel compared to 3.5?

 

a little better but the feeling of the tire is for me better in version 3.5. But the most annoying is the important oscillation that tears my hands off if I let go of the steering wheel lol.
The weakness of resistance to stopping is also disturbing.

fanatec csw 2.5 base
fanatec csw 2.5 base

 

Yes, ok, I think I will just add the grip change to 3.5 and make it 3.6.
Small iterative steps

 

I just tested your latest experimental file (rFuktor 3.6) and I must say I like it. Initially I was surprised how light the center of the wheel felt, it felt so odd that it almost made me switch back to rFuktor 3.5 file. I think the latest AMS2 update had something to do with it so just to be sure I re-tested the experimental rFuktor 3.6 file and this time before going to the track I made a car setup reset to default and after that I reloaded my car setup, everything felt fine after that. No more odd lightness at the center.

I tested the file by driving Formula V12 on Kansai GP and with your latest experimental rFuktor 3.6 file the wheel feels very natural, feel of grip loss is excellent so catching small slides when driving at the limit feels easy and natural. This file is definitely another keeper for me.

To prove once again how good your latest experimental rFuktor 3.6 file really is, I managed to score another new WR. This time in Kansai GP with Formula V12, beating the old WR by six tents of a second.

EDIT: Oops, I did it again... another new WR, second one for the day. This time on Nordschleife, difference to the 2nd place holder (previous WR) is now over four seconds.

EDIT2 (25.4.2021): Today I noticed that someone got very close to my old WR in Brands Hatch GP, difference was less than one tenth of a second. But I managed to improve my old WR by nearly half a second so I think my Brands Hatch GP WR on Formula V12 class will be safe for a while now.

3.6 EXP .... I am just starting out but I feel something strange on the front and then I go to the head of the tail easily ... maybe it's the new setting on the tires ... i don't now!!

But it is still early, I have not changed the relaxation curves and I would not want it to be me who still has to tune in ... even if I have already entered many values step by step ...

@Karsten Hvidberg saw the settings more in the new file but could you give me some more info on what works differently in this 3.6 EXP??

 

It's crazy 8)
