    Haven’t had much time too play, but feels pretty good out of box, maybe prefer a little more relax values like before. front tire bite or skidding is a fraction strong when crossed up .

    Hi you all.
    Again, thanks for the great work. V47 worked very fine on my T300, so I am highly anticipating this even improved version!

    Question: What precisely is meant by Tire Stretch? And why is its value on 0.0? Isn't it an important thing to feel?

    (stretch_feel_scale 0.0) #0.0-1.0. 0 no feel of tyre stretch, 1 most feel of tyre stretch. This works in combination with stretch_feel_time.
    (stretch_feel_time 0.175) #Delta period for stretch feel. The higher the more the stretch is pronounced/felt. This works in combination with stretch_feel_scale.

    Thanks in advance.

    Rob

    .48 feels pretty good, but for me, it would be nice to have a bit more loss over a crest, and maybe a bit more load up through corners. Is there any settings I can change to try and get this? Thanks.

    Won't be able to test properly for a few days, but had a look at the file and look forward to play with these two settings:
    (steering_resistance 0.07) #higher for more resistance on turning.
    (steering_resistance_timing 0.025) #higher for larger time build up of resistance force.


    The steering in the last few versions have been a bit light for my taste, and I havent found a good balance using LFB and gain, so this looks promising :)

    Another thing regarding settings in the file:
    This is probably a (too) big ask, but is it possible to note the useful range for more of the settings?
    For instance, what is the useful range for the steering_resistance above?
    0.00-1.00?
    0.00-0.10?
    Or something else?

    Another solution could be to move the scaling of the values to the functions, and have all settings range from 0-10? Would possibly make it easier to compare the effect of changes to the settings?

    Hey Michael,

    You can change the 8 lines right under "#limit high df" to these 8 lines:

    (x (+ 0.1 (* 0.2 limit_high_df)))
    (y (- 1 (/ 1 (+ 1 x))))
    (FL_load_norm_s (smooth FL_load_norm 0.5))
    (FR_load_norm_s (smooth FR_load_norm 0.5))
    (FL_load_norm_s (if (min 0 (- FL_load_norm_s 1)) (* 1.0625 (- 1 (/ 1 (+ 1 (* 16 FL_load_norm_s))))) (* (/ 1 y) (- 1 (/ 1 (+ 1 (* x (abs FL_load_norm_s))))))))
    (FR_load_norm_s (if (min 0 (- FR_load_norm_s 1)) (* 1.0625 (- 1 (/ 1 (+ 1 (* 16 FR_load_norm_s))))) (* (/ 1 y) (- 1 (/ 1 (+ 1 (* x (abs FR_load_norm_s))))))))
    (FL_load_norm (+ FL_load_norm_s (- FL_load_norm (smooth FL_load_norm 0.5))))
    (FR_load_norm (+ FR_load_norm_s (- FR_load_norm (smooth FR_load_norm 0.5))))

    and then, for more force on cornering, adjust these 2:
    1) "power_steering_lfb" to 0.0
    2) "master_rack" to 1.10 or 1.20

    Hey Rob,

    It's only really adding a slight softening to the feel which DD wheel bases can use. Any belt already has some give in the belt, so I don't think it adds any value, most likely the opposite, since it will further delay the signal form hitting your hands slightly.

    Best, -K

    Thanks for the quick reply. I had already tried the power steering to 0, but was very heavy. I am trying different values to get it where I like it. I will try the others next time I am on.

    Thanks for the explanation! I wouldn't ever have guessed this value had this meaning!

    Any chance you can build in a routine, so every time a new file comes out, the clock in my office leaps forward to end-work-time?
    Asking this for a friend ;-)

    Tweaked the .48 HIGH file today, and although it was close to the .47, it provided those extra lines of code that did provide more flexibility in fine tuning. It's hard to imagine how the files could get much better at this point.
    True magic. Thanks to all involved!

    P.S. I started doing all my set ups in Custom Race Mode, no practice or qualify, just straight to race, ESC and re-start to adjust.

    I would have thought so too, but now the truth is that v48 was actually a much bigger change, it just was too many things and it needed more time, so decided to post this small incremental improvement since it simply made it feel better.
    The big changes are now in V49 and will take a little while longer to finish and make work well. The hope is it will move it up another 2/3 of a full level. Then at some point soon there should be some more important stuff available to the custom file, being done by @Domagoj Lovric at Reiza, and that will make it possible to step it up even further, so hopefully we have at least 1 or 2 more full steps of clear improvements to be done very soon 8)

    Do you guys usually stick to your previous settings when a new version is released or do you start to dial it in again from the beginning?

    Here's my tune early days of .48 so far.

    im running quite low and lite gain and lfb
    25/20/30/5
    but should scale ok.
    decel feel was too strong and oversteer was to bias towards rotation for my liking before.

    Well, with the latest files, some tweaking is needed for each car but the ranges you have quoted should be fine. In any case you should experiment to see what is better for you.

    Hey Kuku,

    Nice changes you made there! In het initial v48 I also had the feeling that the lightness of the wheel during braking was a bit overdone, but with your settings it's more in balance.


    Grtz. Rob

    Do you mean tightness ?
    Because for me it was getting to tight or heavy under breaking and deceleration.

    Unfortunately there is not many other ways to "simulate" braking force on your car/body. On my DD1 the dec2_scale value is just about right, not sure how it feels on Thrustmasters etc.

    But realistically, this might be the only way to make you feel the huge amount of force during braking. If you ever tried to brake fully with race/sports brakes, its one of the most accented sensations in a race car. As an example, F1 cars produce about twice as much G during heavy braking than during acceleration, almost as much as cornering. And its a bigger difference in a GT car.

    Comes down to how good your set up is, if I had a really rigid setup with a proper race seat and DD using a replica wheel etc, I might like more realistic weight, but the realities are I ( like a lot of peeps) am using a plastic wheel clamped or bolted in my case to a desk and sitting on a high backed office chair , meaning more bent elbows than ideal . So while I want the info, I can’t muscle the loads too much and don’t want to have plastic mechanicals of wheel under extreme load. I just have to accept it’s a bit of a toy and keep things light and informative.

    F1 more than twice as much G under braking, up to 5g for that, acceleration G Is pretty low actually.
