Help with my Motec suspension Histogram?

New to Motec but want to learn the suspension setup at the very least, see my Histogram below, what is needed to fix it? I've watched a load of YT vids and can't seem to get the bars to move how I want. Looking at the current chart what should I be doing to bring the peak and overall down a bit in the fronts? (assuming I'm aiming for about 12%) and how do I make the rears a bit more pointy? (Am I aiming for 12% peak again on the rears?)

 

Been having a real hard time trying to nail down exactly how to get the bars to move up and down. I've watched a load of YT videos and some of them contradict eachother.

I've done 200 laps of Imola and one minute I have to lower slow rebound in game to get the slow rebound bars on the graph to go up and the next minute I have to raise slow rebound in game to get the bars on the graph to go up so it seems the rules keep changing. The same goes for wheel rate, one minute when I raise it in game it raises the middle bar of the graph and the next minute it lowers the middle bar. I was trying to put '+' and '-' symbols on the arrows on my graphic below so I knew whether I had to + in game or - in game in order to get the bars to go in the direct of the arrows but as I said it just keeps changing. If anyne can with 100% confidence tell me which arrows should have a plus symbol and which should have minus symbol to make the bars go in the direction of the arrows then I'd greatly appreciate it.

 

Recommend forgetting histograms even exist

 

lol, that would be ideal but when I accidentally managed to get decent looking bell curves my laptimes did actually get faster and the car most definitely gave me a lot more confidence to put it where I want it without it sliding about.

 

Try lowering the rear fast bump and fast rebound. then raise the rear slow bump and rebound. Maybe that gets rid of that binomial character. It's an indication of a digressive type curve vs. a progressive type curve.

 

I think I've lost the setup now that creates that particular Histogram but I'll whip up another one tomorrow afternoon so we can work on that.

 

This is a typical graph that indicates too much fast bump.

 

That goes along with what I have learned so far but sometimes I find that +/- fast bump can make that graph better but also sometimes worse. When I get a min this week after work if I do some laps and post a histogram, would you be able to give me a few pointers to fix it which I'll implement and then post the histogram again so we can see the changes. And my God those two top graphs look perfect!

 

I would say just start out with all fast bump and fast rebound at zero (in ACC), then just add them in as needed. And, sometimes just because the histogram looks good, doesn't always mean it will drive the best. Depends a lot on the car and track.

 

I'll give that a go, thanks. And yeah I totally realize that the Histograms are very subjective but I just wanted to get the hang of manipulating them how I want so I can then build on it.

 

I wrote a big long post about dampers here: https://www.assettocorsa.net/forum/...e-most-from-data-analysis.69903/#post-1202566

If you remove filtering it will lower the graph because it introduces more hi-speed data. If it's still too tall for your tastes and changing damper settings doesn't work, try softening the suspension springs. At the end of the day though, I wouldn't make such a drastic change just to get a nice looking histogram without taking into consideration all the other things that can happen when you soften a suspension.

Also how you look at your histogram matters a lot too. I set mine to 200 mm/s as my max +/- range, which will affect how tall it looks. More important is the distribution numbers up top. I go over all this in my post.

 

Brilliant thank you, I've just got my wheel back from an RMA so I'll take a look at it again.
