The "output real brake pressure" option in Content Manager - how to setup properly?

[Remili175]

I've been having an issue with different cars having wildly different brake sensitivities in AC CM, to the point that adjusting brake pressure in game doesn't address it, and I found this setting in Content Manager that should be able to help under FFB Tweaks in CSP settings. I attached a picture of it.

It's asking for the max pedal force AT THE PEDAL FACE, not at the load cell. How would I figure that out? My Fanatec CSP V3 load cell pedals don't give me a measure in kg and they're probably sensing the pressure at the load cell, correct?

This is the first time I've seen an option this specific, so I figured I'd ask people who would have more experience with this kind of thing. Does anyone have any experience with this setting, and how to set it up correctly? I was surprised to not find any real documentation or experience with this setting when I searched for it. Thanks!

Have you figured out what this does? Im curious myself, just havent had the time to sit down and mess around with it

It's obscure because it applies to a handful of cars that use CSP cphys extended brake configuration. Those cars in particular can use real pedal forces as inputs for braking.

The "max w/o data" line means the amount of force you want on everything else. So for example if your pedal's capable of a max of 60kg, and you set that with 50%, then most cars will reach max vanilla brake strength at 30kg. The majority of vanilla Kunos content is scaled so 100% pedal is near threshold braking, whereas on realistic brakes it's gonna have a bunch of headroom above that (especially downforce cars)

You can get force/weight meters with a point that you push into things to determine force although pull ones are more common. In essence its a scale but most scales don't go to 100KG or so necessary for this purpose. You push inline with the connection its making on the back of the pedal to the load cell (mid pedal usually) and then when it reads 100% the reading on the meter tells you the force necessary at the pedal face.

The challenge I think is getting one capable of the sort of forces we are talking about but its possible to get them even up to 500N but they are in the $100+ range.

Thanks for the replies! Sounds like it's probably worth keeping the setting off then if it only affects a few cars. It would probably feel really inconsistent going from cars without this setting to cars that use this.

Taking apart a $20 bathroom scale is also an option, already calibrated and everything

You could probably make something that forked onto the two feet positions and come to a point on the other end, 3d print shouldn't be too tricky. A bit of tape to hold it altogether. Good idea.
