    Oh,

    Down in the file there's also a "momentum_rack_blend_min" at 0.33.
    If upping "momentum_rack" is not enough, you can change this downwards.
    It allows even more of the momentum rack through, so will make a big difference to lower "momentum_rack_blend_min". Only if needed.

    Cheers

    Santos, sorry, one extra thing:

    Alegunner68 adjusted rack Lfb blend down to 0.25, I think for adjusting stuff it's important you set it back at 1.0, otherwise it might cheat you a little.

    Cheers

    To reduce the road noise either reduce FX in game or set micro_details a bit lower in the file.

    I think Reiza have increased the scrub effect slightly on their side so it could be the interference between the two. Nothing has actually changed in the file itself with regards to scrub for a while.

    Best way to tune them would be to turn only one on at a time and try and get that right then do the other by setting one of the these to 0.0 then the other:

    (scrub_scale_front 1.2)
    (scrub_scale_rear 0.7)

    I reduced macro_detail from 0.4 to 0.3, it feels slightly better, does that make any sense? or it's just a big old placebo!?
    What does the macro_detail really give in FFB? What effects does it cover?

    I did change my settings in-game too.

    The macro details are the small bumps from the track surface. Micro details is more the high frequency noise. And then rack load is for the larger track features and weight transfer felt through the rack.

    So yeah, if you get too much of a cobblestone feel, it is probably the macro details then need reducing.

    I'm using SimuCube 1 Small Mige 20nm and the wheel shakes a lot when hitting the bumpstop with your Custom File, is there a way to reduce it? You may be wondering how am I reaching the bumpstop? Formula Reiza @ Monaco, can't do the Fairmont hairpin curve..

    Hey NuScorpii, I kinda did what you said to find a better balance for me.
    I added more scrub and micro detail in the file, then went back up to the same macro from your default. In-game I went down on FX, and up on LFB just a hint and it's pretty awesome now. Thanks for your help!

    Could you post your tweaked file please?

    I’d like to compare it with NuScorpiis latest.

    Thanks! :)

    Thank you.

    I had a very brief drive with this file today (F309 at Virginia). Feels really good.

    Again, thanks to all.

    What's your Simucube DOR set to? Do you have bump stops enabled in the simucube software? I only get really bad shakes at the bumpstop when the game is hitting the bumpstop at the same time as the wheel software.

    Try changing the lockstop code to this:

    Code:
    # Lock stops ----------------------------------------------
    
    (custom_lock_stop 2.0)
    (stops (bumpstop output 0.15 0.5 0.15 1.0))
    (output (+ output (* stops custom_lock_stop)))
    
    That seems to give a more consistent less shaky bumpstop.

    Update:

    Complete overhaul & simplified in a new series "Silver Raw".

    * Momentum Rack 2.0. New simple full featured rack calculations.

    Momentum Rack 2.0:

    * Simple: Momentum & balance code in lines 91-111 (not shortened for better readability).
    * Details/bumps/large features taken from "load" on each wheel, not from the rack.
    * Balance working.
    * Notch GONE.
    * Both wheels included in calculations each on their own, grip, angular velocity and load.

    Silver Raw 1.0 other stuff:

    * Based on scales for getting the values "absolutely" correct when people report numbers.
    * Adjusted values that should fit other wheels than my own.
    * Might be the core for a last update to the more advanced "Silver Bullet" series, if I find the time.

    Adjustments for features in the top of the file.

    Start by Gain 70 / FX 50 and go from there.

    FX slider adjusts:
    - Rack: Details/bumps/road features.
    - Effects: Road rumble/engine vibes/scrub.

    If you want more of the turn/torque/momentum effect, raise the value for:
    "momentum_rack_scale"

    If you find the larger road features "too punchy", but you need high Lfb, then keep the high Lfb and remove the line that reads:

    "(rack_large (lfb rack_large 0.15))"

    This file feels incredibly fun, love it. One small bug I noticed is if I set the Low force boost to 0 my wheel goes crazy and starts to bounce from side to side.

    Might still be the same issue/bug w/ Reiza if LFB=0?

    Hey Karsten,

    I managed 20 min here and really enjoyed it! Had to try hard to find places to improve.
    For now, the only things I have changed in the file was engine noise when standing still lowered to 0.1 and scrub to 0.4. It was a bit too grainy with the V8 and sigma, but to me now it feels pretty damn good!

    So far great file and overall well balanced, getting all the forces I wanted through the wheel, thanks!
    Running: 70.40.35 atm.

    Update:

    "Silver Raw 1.1":

    * Adjusted friction, scrub & momentum rack strength(still 1.0 in settings, but stronger inside) based on feedback from @F.Santos.
    * LFB 0 bug fix - Remembered to add it in :).
    * Adjusted loss of grip feel.
    * Better self-alignment on loss of grip.
    * Added kerb effect back in.
    * Minor correction to balance calculations on grip loss.


    Adjustments for features in the top of the file.

    Start by Gain 70 / FX 50 and go from there.

    FX slider adjusts:
    - Rack: Details/bumps/road features.
    - Effects: Road rumble/engine vibes/scrub/kerb.

    If you find the larger road features "too punchy", but you need high Lfb, then keep the high Lfb and remove the line that reads:

    "(rack_large (if lfb0Fix rack_large (lfb rack_large 0.15)))"

    If you have a high end wheel and want more linear dynamic range, then lower the gain to keep as much of the ffb signal as possible within 90%(the fully linear part of the custom function that applies compression at the upper end to benefit all lower end wheels) and adjust your wheel base power up from there. It can make for a big improvement.

    Quick question, what is the effect of low force boost in your file? Same as the default?
