Automobilista 2 Force Feedback - Overview & Recommendations

I don't think you'll find more customizable ffb anywhere than with AMS2 custom profiles. If you can't get the results you want using those, it may be time to try a different steering system / or just stick with other titles.

 

I´m not sure if this happened after the latest update, but i had some trouble with my G920 wheel, clearly with the FFB higher than the usual (as before). There was a big gearing noise (i supposed my wheel got broken). I did solve the problem adjusting the Gain level to 80 (it was on 100 by default). Now, it´s the way i desired.

 

buying another steering wheel system is beyond my financial means.

Thank you

 

Question:

Did Reiza ever publish all the available variables/math functions/inputs of the current Madness Engine FFB system?

I still have a list of all the Project Cars 2 FFB variables (even all the hidden/non-publicly released ones) but I was wondering if Reiza added more systems to the FFB/physics simulation.

What are the variables/math functions etc that we have available in AMS2 at this moment? Anybody got a list?

 

Hi,
Do you think you could link me to the info you already have? That would be great.
As an aside, the latest ffb profiles from Karsten has been said to work with pc2 with very small modifications.
I would look in the custom ffb thread further down in general forum and /or pm karsten or NuSorpio as per your question.

 

This is very much an issue with the T300 and I have the very same issues as yourself with the Default profile. If you are interested, I've been creating car specific custom files (based of of NuScorpii and Karsten's latest files) to really dial the FFB in for the cars that I drive the most for the T300. If you are interested, I'll be glad to send them your way if you want to give them a try.

 

"Logitech G920 and FFB Default with game version 1.0.2.5" ... the direction for the development of the FFB seems to me the right one, I notice big improvements in the general coherence, in the counter steering (excellent and without clipping), in the sensations and in the effects .
- GAIN 100 (or 95), it is now possible to play with a value of 100 with less clipping on almost all cars, the steering wheel has constant resistance, clipping is greatly scaled and therefore the force is almost always present without sudden death ... I left 100 but if that little clipping (still minimally present) bothers, lower the value a little until it disappears.
- LFB 20-30, here has been the biggest change I have detected compared to the default FFBs of previous versions, before version 1.0.2.5 I was forced to use high LFBs (80-90) to fill the wheel in the center but with big problems with the pendulum effect especially on very swaying cars, now instead, with this last version, even with low values (20-30), the center remains full in the central degrees even if in a very delicate way, moreover, the pendulum effect has disappeared and counter-steering when cornering and accelerating is very consistent, predictable and controllable. Finally I can prevent the car from spinning, I can manage the skidding of the car and above all I feel the point of no return ... I therefore have a greater feeling of how the rubber of the tires works and it is clearer the transfer of the weight, the work of the chassis and shock absorbers and the final output of the sensations to the car's wheels.
FX (85-100), this cheap wheel needs to be filled with effects and therefore I opt for high values ... this (in my case) does not modify and/or influence the above and therefore only adds what is required, curbs , frame vibrations, etc.

So what's still missing ??? Only a greater definition of what is highlighted ... it seems all present but all soft and not very dry and decisive when needed ... but that's all, it only needs to be pronounced and underlined with a greater definition ... for me then this ffb of the version 1.0.2.5 is a great improvement and I hope it continues like this in the right direction ... great Reiza !!!!

 

This is what I could find quickly from one of my own FFB files.

#General form of code
#(A B ....)
#If A is known function name, then that function is done, with B ... as the arguments. If an argument is itself in (), then that is resolved first.
#If A is not a function name, it is taken as a variable name, and is assigned B, and ... is ignored.

Note, anything that has the tire forces can have the full Mz, Mx, My added.

So example, again from one of my files for pC2:

(Fy (+ (* left_scale FL_Fy) (* right_scale FR_Fy)))

Any good suggestions for FFB settings for the latest build for a Thrustmaster TMX/T150 wheel?

 

A little bit of speculation, but could it be, that the ground of the pitplace isn't completely flat and leveled? Is it the same on different tracks?

 

For F1 cars like V10 2, F Reiza or Ultimate I increase the LFFB Boost to 50, for the V 10 1 to 60. Feels much better to me. And I am using a custom ffb file:

Hi,
Thx so much bmanic.
Although almost all of it is over my head ,I am trying to learn all I can.
Should have paid more attn in high school in the 70s But I was too busy trying to learn to play drums
Thanks again

 

REF - Any good suggestions for FFB settings for the latest build for a Thrustmaster TMX/T150 wheel?
I too would be interested here. i have a TMX and was using the custom files (from the long thread), but since the weekends update they dont feel at all right. I have reverted to the in game Default setup with Gain at 65, Boost 50, FX 20. Problem with the default is there is zero feel re what the back wheels are doing

 

Hey guys, i really have no feel whatsoever when i brake. Coming from titles like ACC and Rfactor 2 i am struggling to feel what the cars is doing under braking. I am running the default FFB profile. Visually i can see the car leaning and all, but the FFB is totally not communicating the brakes and the transfer of the weight. My current settings are 75/80/70/10 with a T300.

 

Hi,
My question is...why can't I feel grip loss in my wheel like I do in rfactor 2,race room and even gtr2. I've really done nothing but test and test. I have a sh""t ton of laps mostly using stock car Brazil and kyalami. So many I'm actually 2 or third on the TT boards
I've tried default and all the custom files.

The feeling I'm talking about is the major reduction of torque on the steering wheel when the front ,or back tires lose grip.
I can feel road,road bumps,berms, brake vibrations, etc but not grip loss.

I've found I have to set the in game ffb gain down to about 30 to not have too much steering wheel resistance so I don't think I'm clipping. I feel other details it seems.

Does any one know what parameter I could adjust in the default copy custom ffb?
Could it be a matter of reversing ffb effect somehow? I've had to do it in other sims.
Please, I love this sim....just this one thing is killing me

Thank you

 

What wheel are you using? If not a dd, then gain should be much higher I believe.
