For the histograms. if one damper shows higher percentage in one way, that means it's spending more time in that movement. So what we looking for is stiffen that damping and that will slow it down? An example: If bump is 38 and rebound is 40 than we need a bit stiffer rebound? Also, is it always best to have them nearly equal?
To start off with, yes you want them nearly equal. The reason for this comes from basic control theory and intuitively you can see in your mind that if you want maximum grip you need the tire to be in contact with the ground and if it rebounds way more than it compresses it will lead to a funky response and limit your grip because that will not lead to optimal damping of oscillations. Once you have a setup well developed and the histograms are decently balanced, you can ask yourself about what the car needs to go even faster. Are you struggling on turn-in? Are you understeering as you apply throttle? Are you oversteering as you release the brakes? If you want to make a change to one of those characteristics you then make a change to the slow damping only and this may throw off the histogram symmetry but it will lead to faster lap times hopefully.
Hey Mauricio I have a question about this answer. I really can't see why symmetry is something that you want to have. It's incorrect to say that if you have assymetry in the speed histogramm your tire will rebound more than it bump, because if that were the case this would mean that the car is constantly going up or down lap after lap. Since this is not the case, the assymetry balance itself between high and low speed, rebound and bump. (So more time spent in low speed bump will automatically means more time in high speed rebound for example) But why would you want to have the same time spent in rebound and bump low speed ? Or why the same amount of time spend in rebound and bump High speed ? For me the aim is to control wheel and chassis mode the best you can, and I can not figure out the symmetry in wheel speed repartition will help for this. Thanks !
There are two versions of dmaper velocity. One is an output channel from iRacing and the other is a calculated channel done automatically by Motec which differentiates the Susp Pos channels. The channel is made already for you but it is usually broken and you have to go to the Suspension histogram properties to fix the velocity calculations. The other channels like hi and lo speed, I made myself.
i watched ep.5 it's all clear now, but not quiet sure how can i fix damper velocities in Suspension histogram properties, i'll check other videos maybe i find it out.
Very intuitive11 Could you please share your workbook as I'm new to Motec and need a template. Appreciate your help. Subscribed!
Does this tuning works for other sims also like acc??
I dunno if you’re going to see this but you ever change them and nothing changes on motec?

Yes, more damping will cause the speeds to slow down and the histogram to look pointier or sharper looking.

If you run out of compression in a situation where it is that unbalanced, wouldn't that necessitate stiffer rear springs as a possible solution?
i dont have damperVel or damper Lo speed etc channels, did you made them for yourself somehow?

I found it already. Thanks for the videos!
