    First, Travel_l/r is the work or force for turn in velocity relation and with vel_rot_scale fill the center, but this work is affected from vel_rot_limit_coef if you low this second voice you can reduce the first, if you high the second you have help with high first value to fill. Is ok 1.5 and 1.25 or 1.26 and 1.14 for most car (i like it), but try at Kansai the formula Cart in the last short but angled and fast curve before the last chicane, the front of car slips without grip in an anomalous way (the travel and the force slip and disappear), it is highlighted only there because there are few sharp curves at this speed (320 Kmh). I used 1.20-26 before, but I preferred to recalibrate the balance with lower values 1.08-1.04 and then modify others voice, Karsten set this to 1.00 and 1.00 but if you prefer 1.5 this is your taste then ok. This are the code for velocity and travel_l/r....

    ## limit rot velocity
    (a (abs kmh))
    (f (* vel_rot_limit_coef 1.1 0.004))
    (a (- 1 (/ 1 (+ 1 (* f a)))))
    (a (/ a (- 1 (/ 1 (+ 1 f)))))
    (a (/ a (max 0.000000001 (abs kmh))))
    (n 1)
    (pn (/ (- 1 (/ 1 (+ 1 (* f n)))) (- 1 (/ 1 (+ 1 f)))))
    (kmh_l (* kmh a (/ n pn)))

    (travel_l (* vel_rot_scale 0.001 kmh_l))
    (travel_r (* vel_rot_scale 0.001 kmh_l))


    -------------

    Second, angle_d_l/r, search "velocity_res_scale" and watch the code under ... you stop here...

    (angle_d_l (- wanted_sa_l steering_angle_l)) # diff from where it would have gone byitself to actual steering
    (angle_d_r (- wanted_sa_r steering_angle_r))
    (angle_d_l (* angle_d_l 2.3))
    (angle_d_r (* angle_d_r 2.3))
    (vel_res (+ velocity_res_offset (* velocity_res_scale (min 1 (* kmh 0.004)))))
    (angle_d_l (* angle_d_l vel_res))
    (angle_d_r (* angle_d_r vel_res))


    Then angle_d/r is where it would have gone byitself to actual steering, so if for example you want to keep the steering at 30° during the curve it represents the force you have to keep in order not to return the steering to its natural position ... in this the speed takes over (velocity_res_scale), the faster you go (vel_res), the stronger your strength because the variable angle_d / l is multiplied by vel_res ... more speed means more resistance to keep the steering curved at the target angle.

    I continue the crusade against philosophy, as I said I have prepared 5 files all in ATMOS 1.4 FIX format and all with the same harmony and let's see why.

    I remind newbies that one thing is the code of the file that normally we not touch (which follows the development done by Karsten 5.0.1-5.0.1.3-5.0.1.4-etc ....), one thing is change only determinateds coefficient in the code of Karsten (change this is equivalent many time to change the phisic or modify it) and another is change the items to be set according to your tastes (many variables normally to be set at the beginning of the file from users), furthermore these variables can be varied up or down by aggregate and to be precise we have 3 aggregate macros, the master_rack (all items for the rack and road) , the master_road (all the items concerning the road texture, bumps, details, kerbs, rear and suspension) and the Effects scale (all the items concerning the engine, scrub, tear and flatspot), and after we have the cursor in game to define and how you set your hardwares.

    Without being an expert you will understand that comparing one file with another makes no sense if you do not equal the starting point, then the solutions are two:
    - use the same file version and therefore the same underlying code, varying only the many variables (this is a job exclusively for tuners and only with this you can achieve very different results);
    - or follow the reverse approach, use the same tuning with the same values in the variables and change the underlying code using the version that suits you best to get the result you want (to do this, however, you need to know well the code and know how to modify it).
    The ideal, therefore, would be not only knowing how to read the code to choose the most suitable version, but it would also be useful to know how to modify it, and also to know how to tune it.

    Only with this premise do you understand that when you say a preference you have not explained anything, because the files are many, the variables involved in the files are so many, moreover, you have different brains, different sensations and different equipment....

    I follow Stakanov's project not because it is the most beautiful one file but because it can become whatever it wants, whatever version or file you like, moreover, on the chosen version you can apply any tuning of your liking and this leads to a clash with the jealousies ... unfortunately the users cannot distinguish all this background, they fall in love with a version, they make up their minds and the stadium cheer is nice and ready. Saying Stakanov's File is better than X doesn't make sense, saying that X is better than Stakanov doesn't make sense in the same way ... but it can become whatever you want, others no because it does not have the extra items that can be deactivated or activated or modified, it just has more elasticity and possibilities.

    It's only a game or test, here we have ALL ATMOS 1.4 FIX with the same tuning, same voices, same values, and only the progressively different code, which starts from 5.0.1, passes through 2 hybrids, arrives at 5.0.1.4, ending with the latest ATMOS. If you insert the files one at a time and test with the same machines and tracks, you will compare the little difference and different codes without the variable of the different tuning ;) ... the funny thing is that I can't wait to take the next most famous file, copy the tune and propose it in these 5 forms :) ... I forgot after correcting the errors!!! :whistle:

    The very slight differences are felt (on the wheels, on the movement, on the suspension, on the center, on the effects and everything else) and practically if I like 5.0.1 or 5.0.1.4 in general, but I want the 5.0.1 or 5.0.1.4 yaw, i just replace the relative lines of code, if I want the 5.0.1 suspensions in 5.0.1.4 I do the same, on the contrary, if I generally prefer 5.0.1 but I want the rear 5.0.1.4, I do the opposite.
    Before, if I was comparing two files of two different guys, I didn't understand it (because too many variables changed between two differently tuned files) now I understand it because the change is for single steps and the comparison between the files is not affected by the different tuning.

    Keep an eye on FFB clipping (tyre/suspension HUD). It requires lowering car specific FFB.
    I'm only have clipping in high-speed turn on braking hard over kerbs - and that's ok for me as we don't need detail in kerbs, what we need is a really good shake as "get out of where!" :)
    BTW, I have my wheel driver @75% max, so it may change thinks a little.

    Thanks for your time putting this info together.
    I surelly have not achieved what I want (we tend to overcompensate what's missing), but my FFB has changed a lot to a point my main concernes about having nice multi-class races are not physics or FFB - is about perfecting Ai :rolleyes:

    Let's change the subject, some of you will remember the user RaceRa**Ra**, he left us some time ago on this forum with the promise (threat) to come back over and over again and with more accounts, he had attacked practically everyone on the forum to the point of being banned from Reiza for the violence and reactions he had shown on this platform.
    Now I have a list of at least 10-15 accounts (this time almost all peaceful and experienced after a few accesses to the forum), who say the same things, use the same words, have the same needs, do even the same things and use the game with the same finality and with the same physics necessity with the same values. Every now and then a new one comes up already trained to put winners or likes.
    Sometimes they don't write all together and disappear (maybe they even go on vacation together), then they come back and one to one they all write little by little (they probably also work together) and maybe they even go to bed together.
    It's really amazing how much people like each other sometimes, I come to think they could even be the same person. To me in 3 years it has happened here only with 2-4 people and in general we use the same file but a lot of different settings, for the rest it was more arguments than loves.

    On top of that, here we have tuners or modifiers who are also friends of youtubers but we will tackle this as well with a "crisp" review, but not for now, only after the review of the corrections code not detected for ignorance and shared by all oblivious to this.

    Forget it, it's not worth it, they all love them equally and most moderate people are silent and don't take part in these supporters, don't fall into their mistake, ignore them !!!

    Reviewing the files I find the movement of the 5.0.1, hybrid 1 and hybrid 2 versions very beautiful, but I like the feeling of 5.0.1.4, the first 3 files have different suspensions, have you tried to move this code to the final ATMOS, the result is not bad.

    @Manolo I would let it go, if it is really as it seems, I am convinced that this is of no use, indeed do not correct anything anymore, let them build their castle of untruths and leave them convinced of what they claim.
    Anyone who knows the code a little, knows and is silent, I can only feel sorry for the user who cannot objectively evaluate the situation because he can not help but upload a file and give an emotional and hasty judgment.

    @AntoAntoDD I'm going to test this combination.

    For anyone with a Fanatec DD1 or DD2, this was just posted in the Fanatec forums by Maurice Böschen:
    FanaLab - Share your favorite profiles - Page 26
    Custom Fanalab profiles for a lot of the cars in the game, combined with a custom FFB file based on rFuktor 5.0.1 with modificatons by Danielkart and Maurice.
    I've tried most of the different rFuktor variants, but I must say that this combination of Fanalab profiles and custom FFB feels really, really good, maybe the best of them all.

    I will try to insert the suspension 5.0.1-hybrid 1-2 ....

    Let's see what comes out if I just import the values of this tuning into the 5 ATMOS .... I'm not interested in beating but just experimenting.

    Can we use a log function in custom files? ("log x y" ?)

    I have a request. Could someone please check and confirm that on custom file generated by the game FFB in Copa Truck (all models) is inverted. I wonder if this is "only me" bug or if it affects everyone.

    Hi all,

    I've tweaked the rFuktor 5.0.1.3 to my own liking for the TR300.

    Main take aways:

    - Dynamic restistance on the wheel at different velocities (very low between 1 and 50 km/h - stronger as speed increases)
    - Pronounced oversteer, back braking out
    - Pronounced brake feel (heavy res under braking)
    - Tighten range for low end wheels left at 0 since it diminishes detail for me and introduces weird vibrations on long straights. Instead I increased the main rack scale to 0.94

    Personally this works very well for me as I know exactly where the limits are of the car in stages from understeer, to slip, to oversteer. Tested on Formula Ultima, GT3, GT4, Formula Retro, Group C, and some others. The FFB is consistent with these classes. I tried to recreate the AC feel of FFB and I'm happy about the results!

    In game settings:

    Gain: 100 (75% in Thrustmaster config)
    FX: 45
    LFB: 0
    Damping: 0

    Wonder what other TR300 users think? I imagine the low FFB in very slow corners is not that informative for some but I like it :)

    Many thanks to the people responsible for the original file, yall MVP!

    Hi I’m using a custom profile which feels great ,
    Which figure do I change in the file for increased brake/suspension effect ?

    if possible ?

    You don't say which custom file are you using, so it's going to be very, very hard get someone to help you...;)

    Look inside... some names and comments are often very obvious - change and see what happens.

    For those using ffb_custom_settings - ATMOS 5.0.1.4 - MOD V1.4 FIX (WITH YAW).txt (probably present on similar custom files)

    I think I found a typo... If anyone is using it, check line 357 or look for "(13" (thirteen, there is only one occurrence) and replace with "(l3" (lower case "(L3").

    is the basic un edited custom file the same as "default" or "default+"?

    thanks

    Hi everyone this is the last time i gave i chance to this game cause i'm really wasting tons of time to try to set up the FFB as i want ( as i have it on AC , where i found the combination that makes me feel like when i'm in the real car ).

    I'm using the custom file from @Thompsonbra and it feels pretty good every where except when i go over a curb i simply can't feel the whell changing hight --> when i go over a curb the wheel dosn't do anything and just shake over the irregularities on the curb itself , but can't fell the feedback of the wheel going on the curb ( i don't know how to explain ) is there a value to change that can modify this aspect ? ty ( the file i use is attached )

    (brake_feel 3.2)
    (suspension_scale 0.35) #how much the suspension is felt.

    Adjust to your own liking.

    Good that you mention it! Feel the exact same way but I thought it might be an AMS2 thing because some kerbs do have this sensation (Bus stop at SPA) while others don't...

    BTW you might want to change the '(exaggerate_front_load_feel)' to its default value which is 0.5 I think. I increased it too much and FWD cars feel too heavy...
