Simracing is difficult. Learning how to drive fast takes time, dedication and persistence. Assetto Corsa Competizione is one of the best simulations with highly sensitive aerodynamics that want to be respected. Telemetry, such as motec helps with analyzing car behavior and finding major issues in the car setup or driving style. Special sim racing hardware also helps with becoming better, but certainly is not the solution to your problems. Load cell pedals offer better feel. Stronger but most importantly more detailed force feedback of e.g. direct drive wheels offer more immersive sensations. Though I know and I've seen throughout the years, people with entry level hardware perform on top level.

[@Vindisify]

This is probably the most interesting video I've seen on youtube regarding setups and motec. Thanks a ton dude!

[@thethirdman225]

At last! Someone actually explains to us plebs how to set up suspension with MoTeC. I never knew the ideal curve or how to adjust it. I still need to learn about spring rates and anti roll bars. Thanks Nils! MoTeC could be such a useful tool for helping people go faster but there is very little about how to use it. It’s like you have to be in on the joke.

Hi nils. Thank you very much for these videos. I understood the histograms, but did not know which values were the target. I test on acc one hour, and only changing springs and dampers improve my pace. I test it on iracing this week, with the Ferrari gte in Watkins Glen, and improve my pace in 1.5 sec. Amazing. Please do more videos like this.

Amazing work.... So hard to find a nice explaination on how to setup suspension/dampers using motec and not only explaining what it is.

[@fightblade]

Great video once again Nils! I think there is a small little mistake when you were talking about the bump stops and their range. If the front bump stop range is high, the car pitches forward during braking or goes super low at the front during compression on top of the hill. But this generates more and more downforce at the front because front splitter is more near to the ground. The worst thing that can happen is that the airflow towards the rear diffusor stalls and you get very abrupt oversteer moment. Talking in rake angle, if you lower the bump stop range at the front and not changing the rear you will get even more negative rake. In your example the negative rake gets less because you set the rear bump stop range lower so the rear suspension can't travel that much anymore and you get less negative rake angle :-) the change in the rear seems like to outweight the change in the front :-) Maybe you meant that in the video, but understood the opposite at first when following your explanation :-) Greetings, Dom

[@SimracingPopometer]

There are so many "if - then" chains that depending on how you start the sentence have to be said differently that I don't claim 100% accuracy in wording :p the written word is mostly the best as there was more time to think about it. Thanks for phrasing it how it should be (:

[@fightblade]

@@SimracingPopometer all good mate. I was just wondering, pausing the video, going backwards, watching it again and then made my head around how it is in reality, but took me at least 10min to figure it out 🤣 so hats off to you, that you explain everything in like a Livestream situation 👌🏼 One question, did you figure out where the ride height in ACC in measured? Is it in the middle of the car and then the lowest point of the vehicle (front splitter, diffusor) ? Or is it measured at the suspension?

[@urbly2638]

Hey Goelz. You mentioned airflow at the diffuser stalling. What does this have to do with the stuff you were talking about? When does the airflow stall? And why does it cause oversteer? I’ve just started playing ACC in the last 2 weeks, so I’m just trying to learn more and more about these GT3 cars and their complicated aerodynamics. Thanks in advance!

Im diving in deep here Pops, into MoTeC - My question: In regards to specifically ACC, where and what should we be paying attention to, in MoTec ?

[@SimracingPopometer]

I see a lot of value in the damper histogram and suspension obviously. Ride height or rather rake changes in certain situations during a lap, to look for balance issues. Evolution of pressures and temperatures throughout a stint. And then its really driver input and tire slip, just to see what you do wrong yourself rather than the car being wrong

[@skyhigh747]

So you say at 08:50 that the "rebound bar" is too high in the middle so you want to increase rebound - but a high rebound bar at the middle means most of movement is happening near 0 mm/sec range. Increasing damping would only make this "rebound bar" higher

[@SimracingPopometer]

If you're into those discussions join the discord - there are plenty of people discussing those

[@albrechtliebenau8667]

at 7 min, that is not true. harder springs create higher damper velocities. its a misconception people think harder springs will generate more grip. its the other way around. so if ur histograms are to flat u have to decrease the spring rate. or more high speed damping. most important thing is, to keep them symmetrically. they should be normalized distributed (gaus'sche bell curve) to statistically have the most grip. which doesnt mean if they look pretty u have a ton of grip. for example daytona or lemans create good looking damper histos because most of the time u drive in a straight line where the dampers arnt moving very much. anyway. good content, good video. keep it up.

[@SimracingPopometer]

all that is correct. i just cant change the things said in a video once I got my mind straight :D

Awesome video! I just started learning Motec, and following the video, I used the same Bin Values. What I instantly noticed, working on the Bentley in Suzuka, is that the top values were way higher, around 17%, I couldn't get it below 16% no matter how soft I went . I got a very good setup from someone, in that, top values are 20% front and 14% rear. I just can't get my head around this, seeing you tried to go to 12% in the example. Maybes setting are off in my view?

[@SimracingPopometer]

dont be too focused on getting all these values exactly as I was saying here. there's way more room in this and also the shape doesnt have to be perfect. All it does is giving you a rough estimation and it should be treated like that. There are no huge gains in this, just fine tuning

Just stumbled on this, great information, very useful. Just wondering how to get the rake angle as it's not one of the default channels. ??

[@horkrust7322]

I dont know man. I just cant get that middle one raised to 12 highest I can go is 8. (Hungary/Audi). But ive set the bumbstoprate und wheel rate to the max und the bumpstoprange to the lowest, just like you told us. Also I realy cant figure out when I have to raise which one to get what result. It doesnt really get that clear in the video I find. Anyways good video mate, keep it up

[@SimracingPopometer]

Hey! It just is A LOT more complex than this.The audi is a different car with different engine placement, with different dampers and different gaps between the individual clicks. We don't know how hard the "0" setting on the damper is on the Audi compared to the Mercedes. The relationship between changes on the rear and the front is important, too. If you raise the rear rebound damping, the bump related bars on the front will also be affected. Clicks on the dampers are not necessarily linear. You will have to really work out how that car responds to which changes. It is not trivial sadly and not easy to figure out. There are not much videos because there is hardly any generalization possible. If you want to get it right, you will need to go deep, there's no easy way out. We have a few guides posted on my discord. Additionally 12% is not the holy grail, it does not work on all tracks, it is a rough reference what to aim for.

[@mraeoius177]

Great video as it makes it a bit easier to know what you are doing and why you are doing it and just what it all means. Any plans on that second video yet Nils? I need more :P And I'm also curious if you ever look at the suspension travel.

[@SimracingPopometer]

I'm checking more if/when the bumpstops are being triggered. I hope I have more time once SRO Esports is over.

[@digitalT83]

Thanks for these videos, very helpful

[@theshark1999]

Question to the Rake Angle: So can you say the optimum Aero "Grip" is, when the rake angle tends to 0? If it is on the straight/highspeed corner at 3 so you can say it didnt reach the optimum rake angle of 0 where the aero performance should be the best? If it is negative, you can say the aero tends to understeer and above zero to oversteer?

[@SimracingPopometer]

no, it works different. rake ( =difference between front and rear ride height) generally adds downforce to the front. for some cars it also adds more downforce to the rear. for some cars rear ride height in general gains downforce on the rear, for some it loses downforce. the overall effect on balance and total downforce then differs per car, so you will have cars that prefer low and cars that prefer high rake

[@marcgSIM]

sehr gut, danke dir !

[@jennesheepskin]

[@shinjitsu6180]

I know that this is a very old video and a lot of things might be different now, but there's something that i literally do not understand about the dumper histogram...how am i supposed to achieve "x" result if by simply changing the bin width all the values change? Let's say for example that i want to reach the 12% with the bin in the middle, using a width of 5 the histogram might show that i reached the 8%, but using a width of 10 it might show that i already reached 14%...so what value should i actually consider to be the right one? 😅

[@jean-marctrappier4436]

Hey Nils, hey everybody, I am a little confused actually, the core is already known and you explained it quite brilliantly but I still fail to understand how to setup MOTEC exactly, the graph you shown was setting up the "slow bump and rebound" under 100 mm/s but on MOTEC you set it up at a much lower value, so what should we use exactly ? Is the goal only to get the same shape, not to reach 12% exactly ? I'm asking this because I've read a ton of articles and seen a lot of video and almost nobody deals with those parameters, if we change values the shape changes and the results as well, so....here is my problem.

People keep telling me you ideally want to be between the 10-12% range, but its very difficult to get the middle very pronounced with this, it starts to square off, but I can get my dampers looking perfect in terms of the graph if its a little higher. I can see with the changes you made, you go between the 12-14%.

The histogram is more of a orientation to show you if something is really off. Depends on track and car specifics and sometimes you just cant get it into the prototype shape.

Do you have a rule of thumb you can suggest regarding dampers when it comes to us console users. Would you always set the fast bump & rebound softer than bump & rebound. Would you always use softer rebound to bump??? Or visa versa or would you recommend running equal bump/rebound. On console we don’t have the luxury of data analysis tools.

in fact its the opposite :D lets just call this video old. you have to think in terms of time for the dampers. the harder the damper, the longer it needs to compress/extend, the more measurements in that area will be made, the higher the bar.

[@zoltanvastag-vasti2566]

Thnx for the perfect explanation, I learned a lot! But should your grey scale range for the slow bump not be 50 left and right adjusted=100 ? ( on your scale is 40 both=80!) On the perfect white Pic that you posted as a perfect curve is 50 both =100. That mean that you never would reach the 6-7 percent left and right near the grey field with the fast bumps.

Hey, in all books i read so far about these topics it's explained actually exactly the other way around. If the bars are too high in some area, decrease the clicks/damping. If its too low, increase the damping/clicks. see: www.springer.com/de/book/9783658155476 pages 262 and 263 see also: drive.google.com/file/d/1Y4v_C4lnP3UDziZaUpBG3Asz8aGPQ1V_/view page 101-104 of this manual

[@SimracingPopometer]

Thanks for bringing this up! I think you are right. I had a flaw in my perception of the histogram. Indeed increasing the damping on either side will lead to more (in number) slower damper movements which would result in the bars closer to the middle becoming higher. I was mixing up the amount of samples with their speed to some degree. Let me use this for a 2nd video on this to try and make the graph look even better.

the histogram is at best an indication. it varies per track how the histogram will look with the exact same settings, which also means, you cant always reach the same percentages for example. you're looking for a rough bell curve. the shape is not affected by the bin width in the sense that the key information wont change. you just have to think what the histrogram actually does. it simply collects all measurements of damper speeds and puts them into boxes. a box is 10 or 20 or whatever number you want wide.

[@Sports314]

I know this is old video, but does bump rate, bump range, annd preload differential impact the bell curve. Right now I have wheel rate maxed on front and rear. Front is good, but Rear tires are very flat on what should be a bell curve.

[@SimracingPopometer]

a flat histogram just means the rear is always somewhat moving - its fine as long as it drives around the track. don't take it as the holy grail

Hey🙂 ich hab mir jetzt schon mehrere dämpfer videos angeschaut und jeder hat eine andere methode. Ich hab gestern für SRO deine ausprobiert und hab festgestellt , dass wenn ich druckstufe und zugstufe höher einstelle, werden die balken links und rechts neben dem zentrum immer höher. Kannst du mir da bitte helfen? Danke😊

[@SimracingPopometer]

Ja, man muss sich das alles mal vor Augen führen. Das Histogram ist eine Statistik, es werden alle Dämpferbewegungen gezählt und kategorisiert. Alle 5 millisekunden wird einmal festgestellt in welcher Bewegung sich der Dämpfer befindet. Also ob er gerade im Bereich der Zugstufe oder der Druckstufe unterwegs ist und wie schnell die Bewegung dabei ist. Wenn du die Dämpfer jetzt härter machst, dann braucht die Flüssigkeit (oder Gas) im Dämpfer länger um von einer Kammer in die andere zu kommen (ganz grobes Konzept). D.h. halt auch, dass wenn es länger dauert, dass mehr Messungen in diesem Bereich notiert werden und darum werden dann eben auch die Balken größer.

[@michaeltauscher_uol4474]

Ohhh danke🙂🙏 ich brobier dann mal zugstufe und druckstufe zu reduzieren.

What is the change you made in 4:24 to display data in a different layout? What properties setup is? The screen changes instantly and don´t know how. Thanks!

[@SimracingPopometer]

I can't remember, probably adjusted low speed and high speed boundary? or some filter also possible. don't worry too much about it, adjusting dampers by feel is perfectly fine

if i maximase for 500 the curve go high, what is the good maximase ? if i put 800 i can reach the perfect curve but is correct or no ?

[@kaischaefer9717]

I got a question there is a point I always stumble upon: the histogram and ideal damper curve. With the Honda EVO I cant get the rear slighly near what you show us. Is the Data the Honda delivers buged? Its a very wide but flat curve, nothing I do can change that, the front axle is pronounced and looks very much like the things you show. The rear is kind of different. I made the springs max stiff. I did them super soft, i eleminated all dampersetting, I put all on max I did crazy stuff in between, the histogram doesnt change that much. would be very apreciated to get some inside.

[@SimracingPopometer]

with the engine in the back there's a lot more mass that's moving around in the rear axle and that usually comes with the rear also moving more and longer until things settle. hence the also get less "no movement" data in the histogram and eventually it looks flatter

[@kaischaefer9717]

@@SimracingPopometer thank you for sharing your knowledge, so for the Honda I can only work on the front axle with what you shown us with motec and the damper histogram. Is there a way (for us not so blessed) drivers to get a idea if damper and spring settings are OK? It's hard to understand when you see the difference in damper setup aka standard aggressiv versus commercial setups as CDA... Is there another way via Motec to judge dampers?

Your videos are amazing, thank you. Is there a way to adjust brake pressure in ACC? Because I've only found the option to adjust brake gamma, but that ist mit really what i am looking for. I want to be able to run less ABS without locking up when stomping on the brakes at high speeds

[@SimracingPopometer]

should work with ABS 1 really. Dont give away braking performance. On high speeds you can even press the brakes fully without ABS. Dont reduce pressure :) (It would be in the setup of the car if you really want to throw away laptime)

[@OtoWinkler]

It is excellent, now just wondering why the track maps look simplified as a circle? Is there a benefit of viewing laps like that? It's quite confusing for me, I'd prefer to see it as a real map. Any way to revert it? Thank you

[@OtoWinkler]

OK, fixed it. Maybe it will help others. When I had your track maps it showed them as a circle (not like a real map, weird). So I have deleted yours and imported ones from my previous ACC workspace. And it worked. Sorry for spamming your KZbin channel with comments :)

[@SimracingPopometer]

:) Motec sometimes just uses a wrong reference lap, that is just 1 minute long and then cant draw a proper track. all you have to do is redraw the track map using a proper lap and the right glat channel

[@OtoWinkler]

[@jcgrobler5816]

Okay this is a real eye opener. Did not think the aero really matters as much. But now my question is on tracks like PR where it is a lot flatter is it better to keep a medium stiff suspension to allow the car some roll or do you just stick with a hard one and then run the possibility of the car washing out in fast turns

[@SimracingPopometer]

Gotta say it depends on the car. Some react very harsh to ride height changes, some don't. Haven't really tested along those lines a lot yet
