GSC Request for an expert drivers to upload a DataAcquisition session

[Rick Malm]

Sure would be nice to have an AI setting where the GSC program makes no mods to control the AI performance since this would show max performance base on driving nearly the best line and with high driver skill. Given this feature, one could compare against something closer to reality. MoTeC analysis could really be a nice training aid.

Since its unlikely that my wish will ever happen in the near future, I have a 2nd idea.
This idea could also be used in the RaceDepartment's premium members group training sessions as well.

Request:
Could some of you winning drivers upload to dropbox some telemetry files captured with the DataAcquistion plugin? Just do at least a few laps to allow tires to warm up. This would allow new racers some expert real human data to compare against instead of only AI data on only multiuser data in traffic. Any track session will do if you already have it. Best if you run alone on the track. This output data comes as a pair of files about 2-4Mbyte and a small 2Kb file.

If you dont have the plugin here is a link.
http://www.rfactorcentral.com/detail.cfm?ID=Data+Acquisition+Plugin
This link also contains a link to MoTeC install that will reads the files created by the plugin.
Its easy to install and you just hit cntl-m in pit lane as you start the session.
Look at the README.txt that comes with the install.

Doing this on a number of tracks would allow a way to document the worlds best laps in detail and would allow a way to find out who is the best driver when there is no traffic.

To get the ball rolling, I will put my novice example files and AI at 85% example in dropbox. Remember I am still 4 sec slower than the 85% AI at Brasiia Full. Using V8 no default.

These files are too large (>1M) for a file upload on RD forum RD so here are links to the files in dropbox public area.

Hi Mr Rickmalm,
I'd like to ask for your opinion regarding the Motec plugin:
http://www.nogripracing.com/details.php?filenr=26691

I think that you have a good method for visualizing any car but the min and max might need some adjustments based on how the car feels on the track. I will have to explore this idea. You might find that the visualization of the amount of non green gives you a hint in the direction to test.
One can get too sucked in the the analysis and think there is not room for optimization. Your link to Spad will motivated me to be more formal about saving MoTeC workbooks/worksheets and projects instead of hacking from one project file.

 

[Rick Malm]

I wrote a very long reply this morning but it seems to have gone to the bit bucket.
I like spad and your histogram solution.

Could you upload some of your motec ld and ldx files for best laps that you have had some GSCE tracks, I would like to see them and compare mine with yours. I am going to focus on Brasilia full and then just move down the list in alpha order learning each track with the same V8 (default setup) until I become a better driver. At some point I will add something simple like brake bias changes and then move on into suspension so your way ahead of me. I assume I will need to match your trackmaps as well so make sure you advise me when you have time to do some ld/dlx uploads.

My thoughts were only theoretical, I'm not that good a racer.
But with some cars with respective setups I noticed that the color scale for the suspension histo wasn't accurate at all.
In my opinion you can only judge the suspension positions and velocities if you are using the right scales.

By the way: I just uploaded some more detailed Motec track maps with named sections and corners, because I experienced that the standard and/or automatic generated ones aren't always right regarding shape, length, or not to speak named references. Hope you find my work usefull. If you need/want others, just PM or post!

 

[Rick Malm]

What if you think of the histograms as just a figure of merit and dont expect them to
be that accurate, just take them for what they are without too much work trying to polish them. Its how the car does on the track and in traffic that matters.

I saw your MoTeC track uploads: how about Brasilia Full since I still need to perfect that one 1st then Campo Grande and Cordoba if you have time. Then I can comment on usefulness. And I will use your Interlagos tracks once I get down the alphabet order.

OK. I'll give that a go.

 

[Marco Versele]

I've uploaded Brasilia Full. See download section.
Don't forget to rename.

 

[Rick Malm]

Got it, thanks and renamed and loaded. In Track report image I can not really see the difference in shape or length at this point. I see the turns and straights are labeled and you used a fatter track width making it easier to see the changes. Do you use track editor to do this and do you make size adjustments or what?

Hi Mr Rickmalm,
I'd like to ask for your opinion regarding the Motec plugin: spad....
http://www.nogripracing.com/details.php?filenr=26691

This issue you posted is a sidebar from my 1st request for people to upload their
Data Acquisition Plugin output files.

But I wanted to get back to you per your request
I downloaded the MoTeC project your referenced. (spad)
1. DataAcqusition working with GSCE does not output
and Tire Temp and the worksheet wants Tyre temps so all these had to be remove
re channels needed to be re added.
2 The suspension tabs refer to Damper Pos which DataAcqusition
does not report. I changed them to use Suspension position since
they might be pretty close to the same on most cars.
3. The springs tab also refers to Damper Pos
I notice that in Spads examples he is using Damper Velocity but in the project often used Damper Pos. I changed the channel reference.
4. Brake. Ref to Wheel Speed is wrong. It Wheel Rot Speed.
5. Virtual Dash No engine or Oil temp channel name changes. No Damper pos, change to Suspension pos.

The project file design still has some issues like Fuel Used per lap is NA and with my version of MoTeC I dont know how to calculate differences between end of laps (just use 2 cursors points and look at delta). Oversteer needs wheel base size as a constant which is not picked up from the veh files, as well as a math for Steering Wheel Angle and Oversteer needs value in the right units. I started some hacks (overstear2) but dont have time to finish more of it and check it. Also missing Track temperature so to I changed the tab to tire slide pct. Removed Ambient Air Temp graphic since its not reported in the data as well.

So I think most of the displays have data showing now and people could use this MoTeC project. I uploaded the zip file for this project (rename the file type from txt to zip).

 

[Marco Versele]

Rick, thank you for your Project. I'll give that a view, but it will need some time before I understand.
At first sight I can see that some of your channels aren't generating anything in my Motec software, so I guess we're working with different versions. Mine is version 1.021.0030 (update on august, 25. 2013). That's the latest I could find on the internet.
On the other hand you've some nice analysis sheet. Gonna have to give this a try.

 

[Rick Malm]

Marco, What GSCE plugin are you using? I could not get my version (1.32) output to be processed with the latest Motec software and had to use the old one recommended on
Data Acquisition Plugin 1.32 download page (link earlier in this thread) which shows
MoTeC. mi2_pro-wxp_1.01.0082 is a requirement for that version.
If you give me the links to a later version for Data Acquisition that works with GSCE and that works with a more current version of MoTeC this would be helpful since later versions of MoTeC allow per lap math calculatioins.

It's an *.exe file, but I had no problems or viruses ...
I installed it in a new Folder.

Inside the file you'll find installation explanation. I didn't reinstall Motec itself, but redirected to the existing Motec directory in the 'yourname.PLR'.
No need neither to reinstall the Motec trackmaps.
Succes!

 

[Rick Malm]

Marco,
From your link you posted I could not find where you did the download, the link you sent was herdProtect analysis of the exe. What is the actual download location you used?
Or what do I poke on on the link page you sent?

Not knowing, I google the file name but the downloads that I see are infected.
My system will not allow this download due to Trojan
W32.SAPE.Cloud9.1 is a heuristic detection designed to generically detect malicious files. A file detected by this detection name is deemed to pose a risk to users and is therefore blocked from accessing the computer.

I also tried the old location, link, where this if found in rFactor but the link is bad.

[Marco Versele]

On the page I sent, scroll down and you'll see a download section (under the 'file PE metadata' section).
You can also download directly from Motec on http://www.motec.com/filedownload.php/mi2_pro_1.0.21.0030.exe?docid=2409.

I said in my previous post that you didn't have to reinstall Motec, but of course, as this will be a newer version, you do have to install it. But I don't have Motec in a rFactor or GSC directory, I just have it a own separate directory.

Hope you succeed.

 

[Rick Malm]

Marco
I tried it in firefox and ie with the
link
http://www.herdprotect.com/chris-ki...e9d6c1968628c6c22e772849f1d30538b6b370ff.aspx
and then under file PE metadata line that you suggested that shows
http://download1102.mediafire.com/nlg4bsqoaayg/.../Chris Kinsman\'s MoTeC Telemetry Plugin V1.4.exe
Poke it and I dont get a download but get another herdprotect site
http://www.herdprotect.com/chris-ki...e9d6c1968628c6c22e772849f1d30538b6b370ff.aspx
I also tried to just cut and paste the link name but its not right.
What is the trick here? More details on how you use these link pages please.

 

[Rick Malm]

Maybe you could upload the exe somewhere that I could get to it. Dropbox or to
mediafire and send me a link.

 

[Marco Versele]

That's awkward indeed.
Here's the link to mediafire with the file:
http://www.mediafire.com/download/fz5yma3ne49c0fp/Chris+Kinsman's+MoTeC+Telemetry+Plugin+V1.4.exe
Keep me informed?

 

[Rick Malm]

Yes that worked and Norton says its clear. I work on this as time permits.
Thanks for a clean link.

Just, installed, now I have to go and change the Project data
to reflect the new names but its worth it to get a newer MoTeC program that has
more math functions. Will upload the project after I getting it working for you at least to the
point that the last project was at.

[Rick Malm]

Well I spent all morning doing names changes and creating some new maths to fix the missing dampers and oversteer channels.
Then i screwed up and tried to save under a new name and lost it all except for my math exports BUT I found out something. Spad must have deleted some stuff or something was wrong. With his stuff and the new GSCE plugin and newer Motec log processor that damper channels were NA. But when I create a new project from scratch and use the same GSCE log file both Damper and Oversteer channels were there. So I would not use the old spad project files if you find stuff is missings like the damper channels that are created from the suspension channels.

Last night I noticed the Oversteering channel is wrong. There is data but what is wrong is that in the math it uses Steering Angle and that is 0 for all time. The earlier plugin did put out Steering Angle Pct There must me something missing in the new plugin that we installed.

I guess one can use spads project file as an example and use a new project and start over with the worksheets that what you want.

I have decided the the FFT plots might be more useful for damper adjustment.
Maybe one could Kasprzak's documents.
He wrote a guide to damper analysis
http://www.kaztechnologies.com/file...E_Damper_Guide-_Jim_Kasprzak_Kaz_Tech_Tip.pdf
and has a web site with class charts
/http://www.kaztechnologies.com/downloads/seminar-downloads/
I dont see him using histograms.

Sidebar:
You might find my math equations useful for getting a plot of Rolling time. Just import the integrate xml into the Math tool. Again rename the attached file type from txt to xml or just try the project file (again rename project file type to zip)

 

[Marco Versele]

That's quite interesting, but very technical! Don't know if I'll understand it all, but I'll give it a try.
The KazTechnologies site is also interesting.
But I'll race now and then first!

 

[Rick Malm]

Marco,
Yes I wish I had a simRacing Cliff Notes on this subject or The Guide to Damper Adjustments for Dummies.....

I created another RD thread about the missing Steering Angle that I mentioned and will make the changes to the project if someone give an answer. I am also looking for a way to modify my old MoTeC log files that will not work with the new version that you suggested and I installed.
