As explained in the wiki
Max force Set the force (in Nm) that corresponds to maximum output, lower values produce stronger output
Think of it as how much in sim force is mapped to the maximum level of torque you've got your wheel base configured to output.
So a max force of 30nm means that when the sim wants to output 30nm of ffb it'll be mapped to 100% of the torque available at your wheel base.
Therefore, a higher max force will result in "weaker" ffb. Say you have max force set to 60nm that same 30nm in the sim will be mapped to only 50% of the torque at your wheel base.
For what it's worth, the setting in iRacing works the same way.
Ok, now I understand it, this means that the maximum Nm the wheel can give will be mapped to the Max Force that you set, and this is specific for every car. For example, if my wheel has 10Nm and Max Force is 50 Nm when the car produces 50 Nm my wheel will go to 10Nm.
The problem that I see is that Max Force is specific to every car but not specified, so how can I know what is the value? Probably the best way is to set Max Force as small as possible, do some laps and then check the clipping, and stop when the clipping is close to 0?
BTW, is the value of the clipping from 0 to 1 or from 0 to 100? and is the unit of measure % or Nm? And what value of clipping should be acceptable, especially for wheels that are very weak, for example I have a Logitech DFGT and if I don't set Max Force to 65 Nm then the wheel is hard all the time. Thanks again for the answer, now it made it much clearer.

The best way to work on this is to enable "Use car specific settings?" This will save each cars settings and recall them when you're in that car next time.
"How to know what value to use" is by personal feel and trial and error.
Drive the car cleanly for a few laps and then exit the car. Look at the log window within irFFB. I believe you are allowed about 2% of clipping before the app suggests you turn the Force Feedback down / Max force slider up.
Find a value you're happy with and that value will be stored for that car if "Use car specific settings?" is enabled.
Also remember that you can change the slider whilst driving the car. For example you can drive for a few corners or laps and immediately decide that the feedback is not enough or too much.
You could pull off the road and change the slider and then continue driving. That's what I do in practice sessions to keep from damaging the car as well as get out of the way of others and still have a warmed up car to drive.
irFFB keeps its settings in an irFFB.ini file in the root of the documents folder of your user login.
You may want to rename or move it elsewhere to start with fresh settings.
Hope this assists you.
I don't understand the meaning of this slider, and it is totally counterintuitive, the bigger the value, the stronger your wheel will react.
