    Hello Rintintin!
    Yes, that is a very big difference in Ams2. Unlike other simulations, in Ams2 there is a "sweet spot" for in-game gain for different bases. If this is not true you will either have a lot of "clipping" and the details of the FFB will be cut off or superimposed or in the other case you will not feel the full FFB details enough or not at all. Now there is the file that is precisely tailored to the forces of the base and thus uses as much dynamic range as possible but at the same time causes as little clipping as possible. The gain at the base is then just your preferred power that you want to feel with your Fanatec dd1 and that can vary depending on the car and the route:)

    I tried your suggestion first with the bump scale and then suspension scale. Then with both even at 0.85 in all four variables I can't feel the bump.

    I also tried JPs fullffb custom file, the bump can be felt with that.

    Visually it seems that when hitting the bump the front right of the car lifts and then as the car lands this is where the bump is felt in the default+ file.

    I hope this information helps you in your future development of your files. They have a lot of potential.

    I will personally try the profile change and the bump at the point where you indicated as soon as possible, hopefully by the weekend... thanks for the details, I need them, I'll let you know if I have any news! ;)

    Hello, I'm a bit lost with custom FFB settings. I find the default FFB quite good, but I would like to try other solutions. I tried rFuktor 5.0.1.3 with my Fanatec CS DD+ (15NM) but without much success. I really like the subtle feeling of the tires on the road surface, but I still can't get a good feel of the car. Maybe my settings weren't right. Does anyone with a CS DD or CS DD+ have any recommendations for this custom FFB or another one?

    Hi again @Stakanov. I have found a reasonable setting for the steering heaviness on braking, but have another question. For me, there is too much loss of FFB when the understeer starts, Wheel goes very light, then, when the grip comes back, it comes in pretty hard. What setting would I change to get a bit less FFB loss in this situation? Thank you.
    Edit: I'm using the Partial NDef_imm file

    I find the most user friendly and also a very good file is JP's FULLFFB. Use the recommended settings found in the file and you will have a good time.

    The Atmos files are also good but takes a bit more effort to find the right settings but they are in the development stage at the moment.

    Danielkarts files are very popular and have given settings for each wheel base.

    Kuku Maddogs file is one of my favourites but I find I have to tweak the in game settings to get the best from it.

    To be honest there are a lot of custom files none are terrible and most are at the least good, only by trying them and tweaking the in game settings will you know which is best for you.

    The default profiles are both also actually good but again with those it will take some time to get the in game settings just right.

    The gain is easy to set with the in game clipping monitor. Set gain with all the other settings at 0 then work through the other settings. Revist gain after you have set everything else. Remember gain can also be set car to car also, I suggest mapping buttons for this.

    Low force boost shouldn't be necessary with your wheel base, but if it feels a bit dead on the straights then knock it up in stages of 3 till it feels right.

    FX is usually recommended to be set at 50 but I find this way too much and have found 0=20 works best. I suggest starting at 0 and go up in stages of 5 until the car starts to feel exaggerated in its movement or the wheel starts to feel grainy, then knock it back a bit, till it feels right.

    Damper, I suggest starting at 40 if the wheel feels a bit quick knock it up 10 if it feels slow then knock it down 10 repeat until it feels good.

    Hope this is at least a little helpful.

    Play with the following and usual lines of code...
    (over_steer_scale 1.250)
    (under_steer_scale 1.250)

    or, play with the damping until you find the sensation you want as if it were the Reiza profile, if some oscillations return, adjust the gain a little lower... sometimes it's counterintuitive and what you're looking for sometimes you get with high damping. .. this custom should not be treated like the original rFuctor ... also remember that in the Immersive versions files (Initial and Partial) there is always the Reiza component for each single car (set by Reiza and not by you) and therefore sometimes it is the Reiza interpretation that is light or heavy... if you want total control you have to use the BASE (only rFuctor) or the BASE+Old_D_raw versions where you establish everything in the code ... in the NDef_Imm versions (which I also prefer) you have to leave some preferences to how they established the cars in Reiza ... ;)

    Damping.jpg

    for example at the end of this image there is the use of vehicle_damping which is not set by you but by Reiza ... while above the other entries are influenced by the Damping slider in the game and this is set by you :)

    Thank you. I will try again. I did try lowering (under_steer_scale 1.250) to 1.00 and have tried In Game Damping from 0 to 50, but didn't really notice it changing much. I will retry everything tonight, along with the base files.

    I have found a pretty good place now, but have another question. When coming off a large kerb, or a a bit of a jump, like you get a the Nords etc, the landing results in a very hard thump, sometimes even nearly ripping the wheel out my hands. Is there a setting that might reduce that feeling? Thanks

    From how you describe it, it's definitely not the Bumps (neither the Micro nor the Large, in fact, especially the latter should be a bit higher as already highlighted by others) ... it should be the dynamic load_norm_wheel which however I don't think it's worth touching now (the code needs to be changed and needs rebalancing the file then), practically in these files it becomes lighter when the car loses weight or rather when the FL.FR.RL.RR_load variables go down but then when the weight goes back up or the car is crushed (+ load) then it spring again at the top (for example in the rally after a jump when you land you should have the same sensation of thud) ... the same thing happens if you hit a big curb while the car has a low load, it shoots up giving the thud, but I repeat, let's leave everything as it is because this helps a lot compared to a fixed load_norm_wheel and so let's try to find an alternative solution...

    Let's see if it can be solved by lowering the suspension_scale variable from 0.50 to 0.25 or even more, to tell the truth Karsten has set the suspension even to 0, therefore deactivating it, but I haven't tried this limit setting yet...
    or try lowering the kerb_bump_scale item from 2.50 step by step 2.00, 1.50 ... even up to 0.50 or 0.25 ...

    in both cases, however, if you lose the feeling with the road or its sensations, bring both values back to the origin

    The answer is YES!
    I was looking for exactly that. Joaquim added a function in his v12 file where the damping slider can be changed to give that light feeling once you understeer/oversteer. Make the changes in the file config and set damper to 70 and you have just what you want.
    I atteched his file with the required changes to adjust the damping slider (with some minor changes to my liking, like higher scrub frequencies, again more like default+)

    Hey man, what would you say is the minimum and maximum range for the two scales? And I assume higher values will give a lighter feeling during under/oversteer?

    The variables FL,FR,RL,RR_sl_lat have a maximum value of 1.00 ...
    (FL_sl_lat (hard_clip FL_sl_lat 1.0))
    (FR_sl_lat (hard_clip FR_sl_lat 1.0))
    (RL_sl_lat (hard_clip RL_sl_lat 1.0))
    (RR_sl_lat (hard_clip RR_sl_lat 1.0))

    I remind you that slide (normal or lat or long) is the opposite of grip... so when the slide is 0 the grip is maximum, when the slide is 1.00 the grip is minimum therefore the two variables oversteer and understeer scales if equal to 1.00 do not amplify the lightening or the slip in this case lateral, if greater than 1.00 they amplify the lat slip ...

    (lat_l_oversteer (* RL_sl_lat over_steer_scale))
    (lat_r_oversteer (* RR_sl_lat over_steer_scale))

    (lat_l_understeer (* FL_sl_lat under_steer_scale))
    (lat_r_understeer (* FR_sl_lat under_steer_scale))

    the quantity or the size of this two variables also depends on other factors, for example from the slip_factor, if you set this latter low (0.00-0.50) you will need larger scales to feel the slipping, if however you set the slip_factor high or close to 1.00 (range 0.75-1.00) as in most of the tire slip models (in my file slip_factor is 0.85) then you just need a little above 1.00 for both oversteer and understeer to get the desired result ;)

    Awesome tx man, are there limits to the values of (ie highest value):

    (over_steer_scale 1.250)
    (under_steer_scale 1.250) ?

    Mathematically, you can't raise it as much as you want beyond 1.00 ... but if you try you'll immediately realize that beyond 1.50-1.75 the steering wheel will become too light as to no longer be coherent either on overstreet or downstreet... as I told you in the files with low slip_factor the inconsistent lightening will intervene higher above 2.00-2.50

    After trying a dozen custom FFB settings, I think my favorite is still the default one, but I really like the subtle 'scrub' effect from rFuktor 5.0.1.3. Would it be possible to add this effect to the default without altering anything else? I was hoping to tune the original FFB custom setting file, but there is nothing referring directly to the scrub effect. Maybe it would be easier to tune rFuktor 5.0.1.3 to make it closer to the default one, I don't know xD

    Thanks for the reply. I had already tried both of those with very little change to the sudden, and forceful turn of the wheel when the car lands. I will just wait to see if you can sort it out.

    @Michael Enright, as you highlighted, I am preparing some small tuning changes to improve the harshness especially during braking in the 2 Immersive type files... and then further changes in the code of all 5 files, some to make the microbumps work better in a less impetuous way and jumping, while others to make the largebumps softer and wider where I actually detected a lack of informativeness as correctly highlighted by @Xzanman...

    Just out of curiosity and comparison, which values have you substantially modified to improve your tuning or test??
    Don't explain everything in detail or the small changes but it would be useful to know just the main variables and what values you attested them to?? …
    Thank you both in advance for the feedback and suggestions on the necessary improvements to be adopted…

    For myself I only Adjusted the four variables that you suggested. I adjusted them individually and then in pairs, and finally all four together. I had no success with any of the test.
