The default ingame apps, telemetry and suspension, how they work?

ok i have 2 problems i dont know how to slove;

1st i drive shelby cobra on lake luise map, first i open telemetry tab, by driving i think i figured out that the yellow line is the end of suspension travel and the red line is the suspension moving...or so?

by this i think when my red line cross over the yellow line the suspension is bottoming out? is that right?

now i tried to work with this, and change dampers setting to get the suspension eat all the bumps without bottoming out. at first i looked like iam on the right path after some time i had something i thought is good.

to try it out i put some extreme values, i made front springs extreme soft and front fast bump extreme hard, only on front, i kept rear as it is.
now the telemetry thingy show horrible data on front, while breaking the red line almost allways touch the yellow one, often going over the yellow line in fast corners and stuff.

but, its makes brutal grip, when bottomed out? i dont understand that, when the suspension travel is at max or over the max(at least that what i think it means), the car just bites the road, it feels extremely strong on FFB(compared to what it was before), the the still more hard rear comes around and you can be very quick in it, it just drive horrible.

i think i dont understand the telemetry screen, maybe it show other data than i think it does? i need help with this.

2nd problem is with the default ingame "suspension" app, that shows the tire temperatures in the middle.

the tire temperatures are extremely unresponsive, i keep spinning the wheels and sliding in turns yet the temperature go casually up 1° in a turn, very slow, i do the weirdest things in car and the tire temperatures dont react at all as i would expect. they go up slow and fall slowly as i drive, but i can not read out actualy tire deformation(by wrong pressure) and effectiveness of camber setting by looking at temperature changes while i am in the middle of the turn?

so far the tire temp app is kinda useless to me, other than to see if tires are warm or cold but i feel that as i drive anyways, but its like the app does not care about what i do with the tires, its just does not react at all.
like when i spin out and tire surface should get extremely hot for short time and cool down rapidly soon after to a normal value, the app doesnt show that, i spin out and gain 1° temperature. how is that possible i dont understand it?

please anyone can help in this?

 

even if my questions may be very noobish, just tell me so and give some links where i can read up on the stuff
since noone post i guess it was already talked about a lot? help

 

sry, cant help you mate...

I´ve done (and enjoyed) more than 500h Assetto Corsa, but still dont understand this (poorly flashed/overlayed)
ingame stuff "telemetry/suspension" apps... its a shame, but true (and to me, it has every reason for it)

Anyone able to explain in a comprehensible way!? thx!

 

Regarding tyre temps, AC show core temperatures of the tyre, thats why they dont change quickly

 

Use motec for telemetry, its way easier to comprehend things.

 

I assume the telemetry menu was once planned to be developed into a full telemetry station, but they abandoned the idea, leaving this remains only. AFAIC these remains could safely be deleted from the program. A comfortable interface linking the data output by AC more comfortably with an external display software like MOTEC, would be more clever now. Right now it can be done, but the procedure is not really elegant nor comfortable.

 

You cant just play with extreme spring rates. To do that, you need to rewrite the suspension travel because of the change in the static deflection.

There are many threads in thr forum that covers the subject, so I recommend you give it a little search button love?

 

ok thanks guys,

now what good is core tire temperature? is there "any" use for it? if my tires are hot or cold i feel while driving, so what else can core temperature help me with? is it just so you can try to get optimal "overall" tire temperatures for the compound you choose, and thats it?

i dont quiet understand. i saw that less spring rate lowers my ride height, i am not sure how to see how much suspension travel i have available in the first place. the values in the setup are all just "numbers". like fast bump 2548? what is that, equivalent strenght to 2548 rubber ducks?
the thing is when i lower spring rate to minimum and add maximum amount of rubber ducks to front fast bump, its drives bad but make good grip while the suspension should just bottom out?

felipe can you remember any "good" thread about this you can link me, if not i have to start searching through all of them. i tried to use search briefly but there where so many similar topics with more or less info in it, it turn me off to look through all of them. maybe i used wrong search parameters.

about the telemetry;

ok good to know i just turn the telemetry off since its kinda pointless? so iam back to square 1, every setup change i did in response to telemetry app was BS it seems?
i never looked at motec so far, is there a free version that works with assetto? i have a single screen, do i need to have a 2nd screen for it? or can it just run in background and still record data and it work?

Works a treat and includes all of the required files. Should do everything you want.

 

Its not pointless, its very very useful if you know what to look for. The yellow line shows where in the full travel range is the bumpstop. When the the red line crosses the yellow, it means that the suspension is compressing the rubber bumpstops. If your car is constantly riding on its rubbers and its not a Bmw, then its probable that theres something wrong there.

The thing is that the suspension travel, in AC, is all relative to point 0, so everytime that you change spring rates, the car will also change its ride height, so you need to recalculate the travel range as its relative to point 0.

Im currently on vacations and on an Ipad, so I wont do the search for you, sorry, its your job, thus, searching and researching the forums is the only way you can learn it, besides, before you start messing with car physics, its highly recommended that you read some real car tuning and engineering literature, like Tune to win, Chassis Design, Competition car suspension, shock absorbers handbook, just to name a few. No easy shortcut really.

 

many thanks Phil_L! this looks overwhelmingly perfect, gona dive into this.

 

@Felipe

ok i see, yellow line is the packers/rubbers, thats why i can go over the yellow line, i was wondering why.
i go use search function.

i think the books are overkill, i just need to know how it works "ingame" and that is not necessarily like it works in real world. it aims to be be close but how close it is is anyone's guess. but thanks anyways i keep that literature in mind as last resort, its not like i wana tune real cars but if i have to read that stuff i guess i have to.
in real life iam not into cars so much, i just like the sim racing. i dont even own a car, just me and me motorbike, 2 wheels, a motor, a seat and handle bars. that all i ever need (EDIT: well maybe add front brakes to that )

 

how does the telemetry option work? how can you select an opponent? or is it that you can only compare it to your laps?
thanks
