    If this application was an ingame feature and is off a few litres, the forum would be full with people complaining. Same with pressure, so many factors are affecting pressure a simple tool wont get the pressure right all the time.

    But people just like to complain, if acc had more "setup assists" all the purist Simracer would complain how this game is too easy.

    I don't get this argumentation. It's easy to focus on the negative and say people would just continue to complain and nitpick no matter what Kunos implements. But what about the majority of players that would be helped with at least a little bit of guidance? It doesn't have to be perfect. Doesn't have to do everything automatically. Even just a little bit of guidance so that players can get more easily to good results on their own would be a worthwhile addition. And I don't see how that makes it "too easy" either, it's rather like teaching people to drive. If anything it helps competition and the game's user base.

    Wow, that was inspired my my thread, let me tell you, I am inspired by you!

    Now this is where the impossible comes in, what happens if Q is dry and R is wet? Could there be some sore of weather implementation that suggests pressure due to conditions or even recommendations for tyre selection?

    What an achievement, I wish I had a brain like yours but then I probably wouldn't need apps!

    Cant wait to try your app!

    Of coarse that would be the result of something like this being implemented by Kunos.

    Just something else for the complainers to complain about, and possible justification as to why Kunos hasn't done something like this yet.

    Is the app by Wally appreciated, and really helpful, of coarse, thanks again Wally.

    But Wally, it needs more automation,... ;)

    I put up a new version in the first post which lets you have different front and rear PSI targets.

    The issue with rain or wet is it depends a lot on the standing water. When i switch from dry pressure to wet pressure i usually have to add 1,0 psi but when the standing water is above 20% is have to add another 1,0 psi. When its now also warm and not cooled down because of the rain you need a completly different pressure.

    I uploaded a new version which tells you at the end of each lap if any of your tyres are, on average, too hot or too cold (using Aris's stated range of 70 - 90 for slicks, 30 - 70 for wets).

    He stated 70-90 is optimal but the dry tires works still well from 60 and up to 105.
    I would suggest to add this region as yellow notice but not as a red warning.

    New version - exclude outlier slow laps from average lap time (for a better fuel calculation).

    Tested your new Version and looks like there is a Bug. Was driving in Qualifying some Rounds. Avg Lap is not filled out.... so we get a INT -2,147,483,648 ;)

    I'm not sure how you managed to do 12 laps and not have an average lap time, but I put up a potential fix (still version

    Here's a beta version of the app that helps you with understeer and oversteer. Feedback welcome.

    You need to enter your car's Steering Ratio (from your setup). As you're cornering, the app detects how often you're understeering and oversteering, which it displays as 4 percentages which indicate how much of the time you're understeering or oversteering while cornering (over the last 2 laps):

    Low speed US
    High speed US
    Low speed OS
    High Speed OS

    If your percentage is 0%, then you are never understeering. The higher the percentage, the more of the readings taken while cornering are in an understeer or oversteer situation. If the number is "too high", try to adjust your driving or your setup to lower the percentage.

    The app also flashes up a red indication when you're understeering and blue when you're oversteering, next to the percentages.

    How it works
    The app measures the ratio of your steered angle (at the wheels, not the steering wheel) to the car's rotational velocity. If you have massively turned your steering wheel, but the car is not rotating much, you are understeering. If you have not turned your steering wheel much but your car is turning around, you are oversteering.

    What you can tweak
    If you're unhappy with the results, you can adjust some settings in the registry, under the key HKEY_CURRENT_USER\Software\Local AppWizard-Generated Applications\ACC Engineer\UsOs.

    SlowCornerSpeed is the max speed in kph that is regarded as a slow corner. Defaults to 120.

    UndersteerThreshold: If the steer/yaw ratio is BIGGER than this number, you're regarded as understeering. Making this number smaller makes the app think you're understeering more often. Making it bigger makes the app think you're understeering less often.

    OversteerThreshold: If the steer/yaw ratio is SMALLER than this number, you're regarded as oversteering. Making this number bigger makes the app think you're oversteering more often. Making it smaller makes the app think you're oversteering less often.
