UFLT - Laptime / Telemetry logging tool

[filthz]

Hi,

Since I was missing a tool where I can compare my laptimes, see my progression and analyze telemetry data I developed a tool that is capable of handling all this stuff.

The tool is currently in heavy development and I think now is the right moment to get some users into it.

At the current stage laptimes and sector times are recorded. Telemetry is in the making, but this is a separate topic because of data amounts etc.
What you need to do:

• Download and launch the client from here
• Launch RR and do your laps.
• Find your recorded laps there: www.010102.de

For those who are interested the stack:
- Spring Boot Backend
- Cassandra DB
- Elasticsearch

Looking forwards to your comments and ideas.

Alex

Do you know the calculations behind this?
I have a module, where you can enter and display any mathematics for your telemetry. Would it help?

There is only 1 person who know the algoritms behind this - and because he didnt get any help inside the iRacing forum when he wanted it he from then on refused to make the code public.
He only from time to time accepted to calculate the grip values of some telemetry files PMed from some of iRacings pro drivers.

Actually its not a secret. Here are some calculations:

Calculating the grip of a tyre for a given surface

Is there a formula to calculate the grip generated by a tyre on a vehicle for a given surface? I have a 13,000 kg machine pulling nearly 200 N of weight. I need to figure out if we need to put any...

.csv export is in the making. It will be a part of the "pro" package.
The formula editor will be availiable soon as well, here is a first glimpse. It can be used to create such calculations as the grip or something similar. In the example below it´s a rather simple formula where the pressure difference between intake and discharge side is calculated.

Until now I have taken your questions rather serious - and have given you reasonable serious answers.
But this time your answer that calculation of grip (in racing simulations) is no secret - and you furthermore post a completely irrelevant link to some (again completely irrelevant) discussion where a bunch of engineering guys make fun with a guy who ask about how to calculate grip for a 13 ton "thing" pulling another "thing" with a force of 200 N.

Absolutely nothing in this link can be used to calculate grip in ANY racing sim - and by suggesting this you only does reveal your knowledge conserning both definition and calculation of grip in such a sim.

The mathematics behind lateral friction are not a secret. It doesnt matter if we are talking about a sim or a real world application.

A Strain-Based Method to Detect Tires’ Loss of Grip and Estimate Lateral Friction Coefficient from Experimental Data by Fuzzy Logic for Intelligent Tire Development - PMC

Tires are a key sub-system of vehicles that have a big responsibility for comfort, fuel consumption and traffic safety. However, current tires are just passive rubber elements which do not contribute actively to improve the driving experience or ...

After digging more in the RR api, the solution is even more simple: RR delivers current tire grip for each tire without any further calculations.

Additional Telemetry channels are being enabled now. Settings are on the profile page.

Happy new year!

Laps are organized in sessions now. Each session has additional infos (weather, humidity if avaliable), number of laps and fastest lap in session.

Clicking on "details" brings up session lap overview with telemetry etc

 

[filthz]

Driver profiles with statistics has been added.

If you dont know this tool yet - https://www.simracingdata.com is a tool that keeps track of all your laptimes and telemetry.
Its even possible to view live telemetry in browser while someone is on track:

Big news - we finally rolled out the lap-by-lap comparison feature to our Pro users.

This video shows how it works.

Enjoy!

Update:

Each session will show the fuel usage per lap now. With the fuel calculator its possible to get the required fuel amount with either the race duration or amount of laps.
