Setting logitech profiler to 120-150 on G25.

So I put a real car wheel rim on my G25 and while it is a great mod it does lower the forces you feel from the FFB. I've setup AC so the FFB does not go in the red, and then went the try increasing the forces from the profiler. It works with the only problem that when in a RACE CAR and standing still there is a vibration which rattles the wheel. The higher the overall forces % the stronger the rattle. Anything above 100 introduces this vibration.
It is great having stronger FFB, but I am worried the rattle will damage the wheel.
Is anyone aware what causes the vibration? I guess it is the physics and ffb of AC since it only happens in a race car. Solution?

 

sometimes when I load a hotlap my g25 will shake too. It just has to do with bugs and kinks in AC's ffb I think. I don't get that in any other sim but have always gotten it sometimes in AC. When you drive off and are driving around do you feel the constant vibration? If not then it's just AC's ffb glitching when the car is stopped.

 

It's basically a feedback loop.

1. AC tells wheel to turn left.
2. Wheel turns left but goes past centre, so...
3. AC tells wheel to turn right.
4. Wheel turns right but goes past centre, so...
5. Goto 1.

 

No, I get it only when stationary. Also a high force induces a behaviour I see in GT games. When driving in a straight line if I let go of the wheel it starts shaking violently left to right and back.

So is there a drawback to increasing the forces level in the profiler?

 

I have that same rattling when standing still with the DFGT.
I thought it's meant to simulate the motor-rumble. It would be good, if you could turn it off though.

To decrease the rattling in general, try the filter setting in AC.
I have set it to 50% (with the G27 you can probably take less). It smoothes out those aggressive little spikes, which do not only feel unrealistic, but also make you worry about your wheel.

 

Known issue at idle in car. Causes crazy vibrations at standstill. Devs are working on it.

Try pressing break and see if the vibration stops

 

With the profile at 120-150 you will create lots of clipping and oscillations, even if the red ffb clipping bar shows no clipping from the sim, you will be creating clipping at your wheel.

 

I have a modded 310 m''m G25 rim and a light modded pedal shifters from Derek Spear. Honestly, to be fast you need to lower the forces so it is easier to catch the slides or counter steer...

In profiler my forces set to 100 and in game any force above 75 gain feels to me too high and sometimes I worry to apply high forces because I can brake my wheel fighting it...

This is my wheel with stock shifter pedals, would like to see some pictures of your modded rims...

 

Mine is hideous, but they had no black leathered in stock and i am not the patient type. It has holes for the buttons, though.

 

Ssuspected that. So, everything above 100, causes clipping?

 

No. If the bar doesn't show clipping, there is no clipping. By setting the forces above 100% you just boosting the low forces and sacrifice the linearity.

No clipping from the sim, but you can still create clipping at the wheel if your FFB is compressing the FFB at higher force levels due to running the profiler over 100% and making it more non-linear, the wheel will feel the same whether it's receiving a 70% or 100% force signal.

That's what happens when you fun over 100% profiler strength, the top end gets compressed, and the mid and low range is artificially boosted, this means you'll be feeling heavier forces than you should earlier on in the steering range, plus your wheels FFB will max out earlier making the top 25-30% of the FFB signal feel the same.

 

Here's some good info too re. FFB, from RD: http://www.racedepartment.com/forum/threads/like-your-ffb-strong-think-again.30763/

 

It doesn't work exactly like that. Setting profiler above 100% boost the low forces, so for example instead 10% you feel 30% - it is still far away from clipping. You're just compressing the dynamics and not introduce clipping. If the sim shows, that there is no clipping, there is no clipping.
