Camber Extravaganza 2.2.1

Real time optimal camber calculator

  1. Chuzuki
    Camber Extravaganza

    App for Assetto Corsa to show wheel camber angles in real time, helpful for tuning suspension.

    Shows instantaneous and peak camber, and has an optional short-term history graph with some settings to play with.

    Calculates optimal camber from config files - per car, per tire compound. Turns blue when camber is too negative, green when near optimal camber, and red when too positive.

    Installation

    1. Extract the apps and content folders to steamapps\common\assettocorsa\
    2. Enable the app in Options > General
    3. Enable the app in-game

    How to Use

    Adjust camber to try to keep as many wheels green as possible through turns, giving preference to the outside wheels. If the outside wheels are mostly blue, add more positive camber. If the outside wheels are mostly red, add more negative camber.

    Once everything is mostly green, add some positive camber to the fronts or rears to tweak balance if necessary.

    Mod cars

    If your target camber is showing 99°, the app can't find data for your car. You can add it to a custom file `tyre-data-custom.json` that won't be overwritten by updates.

    For example, adding [garyjpaterson's Dallara FX17](http://www.racedepartment.com/downloads/dallara-fx-17.13928/) with semislicks (short name "SM") would look like this:

    Code:
    {
        "dallara_fx17": {
                "FRONT": {
                "SM": {"DCAMBER_0": 1.2, "DCAMBER_1": -13.0, "LS_EXPY": 0.81}
            },
                "REAR": {
                "SM": {"DCAMBER_0": 1.2, "DCAMBER_1": -13.0, "LS_EXPY": 0.81}
            }
        }
    }

    Adding any more cars follows the same pattern as tyres-data.json, for example a fictional Abarth 500 Stage 2 with Soft, Medium, and Hard slicks:

    Code:
    {
        "dallara_fx17": {
                "FRONT": {
                "SM": {"DCAMBER_0": 1.2, "DCAMBER_1": -13.0, "LS_EXPY": 0.81}
            },
                "REAR": {
                "SM": {"DCAMBER_0": 1.2, "DCAMBER_1": -13.0, "LS_EXPY": 0.81}
            }
        },
        "abarth500_s2": {
                "FRONT": {
                "S": {"DCAMBER_0": 1.2, "DCAMBER_1": -13.0, "LS_EXPY": 0.8071},
                "M": {"DCAMBER_0": 1.2, "DCAMBER_1": -13.0, "LS_EXPY": 0.8071},
                "H": {"DCAMBER_0": 1.2, "DCAMBER_1": -13.0, "LS_EXPY": 0.8071}
            },
                "REAR": {
                "S": {"DCAMBER_0": 1.2, "DCAMBER_1": -13.0, "LS_EXPY": 0.8071},
                "M": {"DCAMBER_0": 1.2, "DCAMBER_1": -13.0, "LS_EXPY": 0.8071},
                "H": {"DCAMBER_0": 1.2, "DCAMBER_1": -13.0, "LS_EXPY": 0.8071}
            }
        }
    }
    More examples can be found in the full `tyres-data.json` file.

    Calculation Details

    Grip in Assetto Corsa is multiplied by a factor determined by camber.

    [​IMG]

    Where c is camber measured in radians. Converted to degrees and plotted on a graph, it looks like this for the Ferrari 458 GT2:

    [​IMG]

    Peak grip for a single wheel (blue) is acheived at roughly -3.3°, but the total axle grip is the important value. As the inside wheel during a turn effectively has inverse camber, it must also be calculated (red) and added to the outside wheel, weighted by the tire's load sensitivity factor. This gives total grip for the axle (yellow), peaking somewhere below the single-wheel target.

    More Math

    DY_LS_FL is front-left load sensitivity, TIRE_LOAD_FL is the vertical force on the tire in Newtons, and the rest of the variables are found in the car's tyres.ini.

    This is incredibly useful. Amazing the excessive negative camber I was generally using in the rear! Thank you!

    logfile with a recommodation how much the camber should be modified would be excellent.

      All the calculations are done in real time given the dynamic Gs and camber changes from suspension geometry. Asking simply to just give you a number isn't feasible. Switch to delta mode and adjust from those values.

    Good app, though i would like a mode with more contrast for VR, especially the lower numbers are almost impossible to read

    Fascinating gizmo to play with, particularly in conjunction with a skid pad. Perfect for a velodrome; for Cadwell, not so much. Some values are frozen in replay (bug or featch?). Five stars for concept, one or two less for execution. But you deserve a gold medal for trying!

    Very useful. Great Job! Could you please explain the "target angle"? And it´s a bit hard to watch the values at the app... It would be great if there would be a kind of logfile with a recommodation how much the camber should be modified. Again, thanks, would give 10 stars if possible :)

    So far I've only used this with a few cars but wow, I'm loving this app! Camber is one of those things in my setups that I was always worried about adjusting too much one way or the other and this app has helped immensely with that. Only issue I have so far is that sometimes the target numbers do not get me into the green, but having the real time visual graphs help me adjust on my own when needed. Thank you so much Chuzuki, great job! 5 stars
