Automobilista 2 Custom Force Feedback - Overview & Recommendations

what setting causes the self oscillation of the wheel?

 

I got the post section wrong, sorry

 

I prefer the previous file. Couldn't get on with the new file. Good to have options and thanks for your hard work.

 

Hi Richard, I'm waiting for my R12 so... what are your settings (Moza software)?
Do you use "Road Sensitivity"?

 

Hi JP i am running moza ams2 profile but with game ffb int up to 100% in game 50/0/24/50

I feel the same. With two mini bass shakers, one in pedals and the other under seat, I get rid of all FX in FFB, because it don't mix well with other vibrations (the frequencies aren't the same for the same input effect to be simulated) and mask pure steering FFB.

To keep it simple, FX in FFB is useless with good calibrated haptics in pedals/seat/rig.

 

As I said, the more immersion hardware you have, the more other senses are served. Some people adjust the butt kickers as if they were being kicked by a horse. Or the motion as if you were riding a roller coaster. No wonder you can't feel anything on the wheel anymore. For me personally, the feeling in the steering axle and on the wheel is the most important thing to feel the car and the track. To put it briefly, the FFB gives me the connection and the feeling for the car, then there are subtle additions from Motion, buttiker or something similar

 

Could someone with knowledge please explain the difference between the tyre_resistance1, tyre_resistance2 and tyre_resistance3 entries in the custom ffb files plz. I have experimented with them, but it would be nice to have a clear understanding for what they do.
Thank you.

 

FullFFB by JP

This is a full-bodied FFB!!
It is not for everyone, some may prefer a cabin by a bend in the river...

The final goal is to include all forces acting on the car, while been front axle biased (that's where the steering wheel is connected, right? )
It should shorten the incoherence between visual and tactile effects in AMS2, that many identify as a physics related problem (the visuals show information and FFB is completely mute to that, leading to a cognitive dissonance).
If the car moves (track/crash bumps, lateral and longitudinal weight transfers, etc.), FFB should signal that in some way.

It's assumed a linear/neutral profile on wheelbase software/driver.
Some manufactures may add they own telemetry interpretation on top of FFB provided by the game. That could increase (if in phase) or cancel this file's FFB details (if in opposite phase).
Please, control clipping (histogram, last bar, on tyre/suspension HUD), PARTICULARLY if you have a strong wheelbase. That (red) bar can appear on high suspension stress situations (high downforce + high speed turn + hitting a kerb), but just a touch.
This file assumes a (safety) best practice of limiting max torque at wheelbase software/hardware, not by reducing GAIN in game.
Use vehicle-specific gain (changeable while driving) to adjust FFB (low downforce cars may require adjustments, while LMDh and F1 should not).
From v6 onward, vehicle-specific gain has a double impact and is the best method to adjust clipping behaviour.

FILES:

 

There are 3 areas for tire_resistence. Additionally, tire_initial_resist and tire_resistence_timing are also included.
Tyre_initial_resist is the initial resistance of the tires when turning.
Tyre_resistence 1.2.3 is the resistance of the tires when turning, the higher the more resistance. And finally, tire_resistence_timing for a longer build-up of tire resistance. However, in my experience, tire_resiatence_timing should be left at 0 because otherwise there will be anomalies in the steering (too much delay in the steering).
Test everything and decide what feels best on the wheel.

 

Thx Daniel, I understand the fact they deal with the resistance and build up of resistance, but why are there 3 of them? TyreResistance1, 2, 3, what is the difference between them? Do they represent the force on the tyre at different track grip levels or different tyre heat levels?

 

I don't know for sure why there are exactly 3 tire resistances. You would have to ask the producer of the Original_dateien (Karsten Hvidberg). I always imagined it with 3 zones, i.e. on the outside in the middle and on the inside of the tire. Maybe it's your theory? But in the end, I don't really care, the main thing is that it works

 

I can't help thinking the second thing you change here is a direct result of trying to fix what the first setting does...

 

Thx again Daniel, I had not considered the different parts of the tyre, that seems the more likely scenario.

 

Sorry, I meant, "steering lock" (there's no steering ratio). Will change that.
And they are two different properties. One affects the transfer curve (linearity) and the other the absolute max turning angle of the wheels.

 

Is this for belt driven wheels or DD? I think you mentioned you're getting a Moza iirc.

 

Yeah I knew what you meant, it just seems that you're having to increase the steering lock in cars because you've moved the sensitivity to 100%

I tried your file and yeah for me to use it it would need scaling somehow with the steering lock - default lock it was like cycling over cobblestones on a bike with solid tyres (I can't remember which track but it was one of the Brazilian ones with long sweeping bends on it) Upping the steering lock made it feel better.

TBH with a geared wheel like I have that has a sloppy centre the only way really to drive it fast, especially RWD cars that are going to oversteer when you plant at the apex means less force because trying to correct the steering when it's going from effectively no force -> heavy is much harder. It'd be like trying to modulate an accelerator that took hard push for a bit and then suddenly went light - you'd press it too far every time you reached the light bit. Then if it went heavy again you'd be thinking whatever information someone is telling you you're getting it's more of a hindrance than a help.

I noticed too light and you end up spinning simply because it becomes difficult to simply point the wheels forwards and accelerate in a straight line, but too much and now the difference means you overcorrect or undercorrect. There's a sort of sweet spot (which may vary from person to person I suppose) but which, sadly is not really "nice ffb" and nothing like reality.

Maybe these 'light heavy light heavy' custom files work better with a DD wheel that doesn't have a sloppy lack of force at top dead centre.

 

Hello everyone I'm new in the world of AMC 2. The first thing I want to note is that an amazing simulator, you can finally delete ACC
I, like everyone else, wondered about feedback, but the suggested options on the forum, unfortunately, are not suitable for use. Going out on the grass, the effort should be minimal, in all the settings that I tried, wheel slip or loss of connection with the roadbed does not give any information. I can't go to TC 0 because I don't feel the moment of the wheels breaking. I decided for myself that for the time being I leave the default Custom settings for my ALpha 15 nm, where I can safely drive on the vehicle 0, and I get on the grass or tearing off the wheels, I feel the lack of friction force.

 

Sorry, sent you a private message about this, but I'll expose the idea here, nonetheless.

I believe there is a "max torque factor" and a "manufacturer factor" into how FFB feels.
I believe "belt" or "DD" don't qualify as factor/category on it's own, but I know what people mean (is more like a "torque range" categorization, low-mid-high).
