Hi all, I'm still digging around in the telemetry and now looking for anything that might resemble the front and rear downforce vectors on the car or at least anything that can be used to derive them. I saw mWings in the sharedmemory, but that appears static, so I suspect it's just the settings. There is a mLocalAcceleration, which I'm already using to calculate the lat, long and vert g forces on the car, but I'm not sure if that can be used to derive the centre of lift Any clues?
CoP is a downforce calculation. And Downforce is a load calculation. CoP = DFr/(DFf+DFr)*100 DF = SpringLoad + ARBLoad + DamperLoad Hope that provides some insight.
It gives me a decent starting point of where to look. I'm already reporting the suspension travel so I'm actually thinking it might be better to do this with a calculation in i2 based on the car setup. At any rate I have some bedtime reading sorted for a few days Ta!
I have seen that, and it's a great app.... the only issue I have with that is that it seems to take a fixed value of 150Nm/s for the spring rate, which if I am not mistaken means you'll be assuming both the rear and front spring rates are the same. Whilst the absolute value is likely to be incorrect, this should still be fine for calculating the downforce ratio to speed in general, however it's likely to give the wrong value when you try to determine the centre of lift
Interesting! I always found the numbers reasonably but different from RSTsoftware and as you said they do have some utility but not so accurate specially if you using Motec. Thak you!
In RST, if you don't get the and the ARB Load values right, (or at least close) the data graphs will look odd. This why ALL the AMS2 set up values need to be visually seen, even if they are locked in place.
So a custom worksheet is needed for MoTec to properly calculate Downforce? This needs inputs then from the driver on the car’s setup
Because downforce is not a direct telemetry output from any sim then any telemetry tool have to calculate the value from some of the different directly/simple output channels. ByTheWay: I guess you will have dificulties to find a direct setting among AMS2s car setup params saying: Downforce. OK?
I meant that, ALL the in-game car set up values seen in the menus should be visible, and if they're not adjustable, just greyed or dimmed. Not having the values (for whatever reason) doesn't help users in setting up telemetry analysis values used within the telemetry software. If there's some valid reason not to publish the values in-game, then all the user can do is estimate what the value might be, possibly from another similar car type, or data from another SIM that actually may have published it. Not exactly accurate, but what else can you do. Even web searching sometimes doesn't allow the values to be known either.
Reiza should try and make the setup able to be recorded by telemetry apps so it can be used in calculations
