The Feature Request Thread...

Request: The same TV stile replay for VR users. The replay when using VR is from a VR perspective. Not as fun as when using the screen only.

 

Please make the ICM element movable on screen.
I'm not able to fully see it through my physical wheel.
I just want to be able to move it to the left a bit.

Cheers

 

Display drag coefficient and downforce with stats.

 

Why do you want to see drag coefficient? I have requested them bringing a feature showing downforce relative between front to back like in ACC

 

In multi-model classes is important to understand all the differences between cars. I know that in both F1 and GT3, this plays a huge deal differing each model.

And, yes, the downforce being displayed as in ACC would be fine, but I also want to know how much max DF each vehicle can build (each F and R). Some graphs for each car wouldn't hurt... for DF F/R, power, torque, etc

 

Like this?
Use SecondMonitor

 

It doesn’t show drag from what I can see

 

Downforce instead

 

That could be useful, but I think percentages are maybe easier and better than raw figures

 

Just use "Cd" followed by a number... the large the worst. Maybe give two numbers, one for the car with all refrigeration closed and less wing and other with everything "open". No big deal, but very useful when comparing vehicles.

 

I would more like a percentage of showing downforce rear versus front of a car. This makes downforce setup easier knowing how much rake changes things.

 

Understand.
Center of Pressure, I presume, and you can get that from RST Software telemetry.
I'm not an expert user of SecondMonitor but I believe it is possible to mount a trace there based on (rear DF/ (front DF + rear DF) )* 100

 

One thing doesn't exclude the other

 

I have no idea how I would be able to do that

 

Please give me some hours...

 

Does secondmonitor have custom worksheets like MoTec?

 

Don't know, I have only a superficial knowledge of SM but I think you can do it.

Edit: But you don't need a new trace as you will see next post

 

Numerical example: Porsche 911 GT3 / Curitiba / Defaults

Sorry if it sounds pedantic, that's not my intention but I prefer to go into basics to give others in this forum to also take advantage of this.

Using RST you have: Axle load (N), CoP (%), Rake (mm), Speed (kmh)

Rear load trace is mostly outside bounds but it doesn't matter since the actual values are on the right panel

Cursor is at max speed on purpose.
Zero Brake and 100% Throttle.
There you have F_DF= 12631N and R_DF= 24677N
So R_DF is 64.5% of Total-DF wich is known as CoP (Center of Pressure).
And please don't bother with exactly numerical values, since the graphic is made on-the-fly and admit some small variations.

The standard target window of CoP is in the 55-65% range and our data sugest it is okish. Confirmed also by Rake near to zero.

RST IMAGE

Using SecondMonitor at aprroximately the same track position, you have: Speed (kmh), Overall DF (N), F_DF (N), R_DF (N), Rake (%)

F_DF= -18956, R_DF= -11232N, T_DF= -30188N
wich leads to CoP = 37.2%

SM IMAGE

Wait! CoP don't match between apps! Don't panic as both calculus are correct.

AMS2 telemetry doesn't directly give any tyre or axle load value and the apps have different approaches to estimate the loads. According to SM and in order to mantain compatibility with other game titles, all the vertical loads are negative numbers in AMS2 wich are not a mere -1 times change, while RST follow another route of calculus, more intuitive to the user.

Don't know but it also appears that F_DF and R_DF traces could be inverted or maybe a consequence of the negative forces involved, anyway if you consider it as positive number you may re-calculate CoP as (100- (R_DF/T_DF)
and then CoP will be 68.2%, a good approximation of the RST result.

The analysis don't stop ends here but is in a good way to go furthermore to fine tune.

Hope it helped you and someone else.

 

What does ACC show? It has low percentages. Does it just show how much more or less the downforce is on the front than on the rear?

 

SM you mean?
Take a look at the Rake graph in both images, they match!
Also look at the DF traces, they have the vary very same pattern.
And both are right, even with different numbers.
