    Moved the "main thread" of this application here. The older thread was in Apps section.

    This is the tool to make you drive faster regardless of your driving level.

    The tool can be used both during and after the sessions to analyze telemetry data, car behavior and race history.

    Key features:
    • Realtime and offline (after-the-fact) Telemetry
    • Compare your own laps (speed, controls, forces, line driven etc) in many different ways
    • Compare many laps at the same time
    • Opponent laps: Speed, time and gear traces from your opponents from online or offline races are saved, and you can analyze and compare them to your laps to see where you are losing those tenths.
    • Use Math Channels to look deeper into the data to e.g. analyze your setup changes
    • In real-time map see position of other cars + the pit window (i.e. where you will land after successful pitstop), same map can be used in offline to see the driving lines
    • Extensive data for race, fuel use averages (also per fuel mix mode), how much to refuel etc.
    • Very accurate time Delta to other cars
    • Race history, which you can also save for later viewing
    • DriveDNA: Tool to view your consistency over many laps
    • Can reside on the same computer as ACC or e.g. on separate laptop.
    • The tool can be run in Windows, Mac or Linux.
    • Data can be forwarded to another location, where e.g. your race engineer can work on the data
    You can download the tool from RaceDepartment: https://www.racedepartment.com/downloads/telemetry-tool-for-acc.34563/

    Before installing, read the ReadMe.txt inside the .zip packet. I have also put installation and guide videos on Youtube.

    Enjoy, and get faster.

    PS. Some screenshots:
    RaceEngineer: View a race engineer could use to look at the driver's data

    Telemetry, telemetry traces + user defined math channels in the same view

    Multilap, compare traces from different laps in easy way

    Map, real-time map also shows the yellow flag sectors

    Race Timing, race timing has info about how many pitstops other drivers have made, their best and last laps.

    Statistics, statistics of current lap, fastest lap and for the duration of the session. Handy e.g. to see total fuel usage, tyre temp ranges + max tyre pressures.

    Driving, basic driving data, e.g. wheel slip is visible and temps and pressures and estimation for the repair time needed.

    Racehistory, graph normalized on leaders laptimes. There are few other graphs, like per lap track position history, history compared to your laptimes etc.

    RaceInfo: This shows laptimes listed + fuel usage statistics (per ECU mode). If you need to do many refuels, this will also show how much you need to fuel per pitstop to make it to the end. This also shows the time history of cars around you.

    DriverDNA steer. Visually see, how consistent you are on driving. You can see the data on few key controls, like streering, braking and throttle.

    BTW, this tool also works with AC (both PC and console version).

    Some limitations with the AC
    • On the console version track detection doesn't work, so you have to change the track by hand, when you start in new track.
    • AC the tool works as single car tool, so there is no racetiming or race history etc, as there is no proper data from other cars.

    Version 10.5 of the Telemetry and Race Strategy Tool is here.

    The new version is at https://www.racedepartment.com/downloads/telemetry-tool-for-acc.34563/

    Biggest addition is system to sync your laptimes + basic lap data with a global database. When there is more data, I will add functionality to the Tool, which will allow you to compare your own times to the times of other users of the Telemetry Tool. The tool will ask consent for sending the data, when you start it for the first time.

    For old installations run the 'Fix database' from the Tools menu as there were some car id issues introduced by the latest ACC release.

    Notable ACC related additions
    • In online or other events, added to Map the gear indicator to opponent cars
    • Fixed issue, where on online races many players' TLA was "PLY".
    • Fixed car id issue introduced with latest ACC version.
    • Proper ACC tyre compound data is saved to the local db
    • Fuel at start values were bad for first out lap. This was fixed. Still if you "fly" back to pits, the fuel values for that lap will be "odd".
    • Opponent lap saving: Fixed issue, where the opponent lap might have 0.000 or near zero laptime.
    New general additions
    • Multi-histogram view
    • Multi-XY-plotter view
    • Map: Border color added to leader, car in front and behind for easy detection
    • New trackfile format, which is more compact + also loads bit faster.
    • Tyre pressures are now saved to lapdata files
    • PgUp and PgDown work as zoom in all views (handy if there is no mouse scroller on the system)
    • Many little fixes and tweaks.
    For update, backup old installation, then unzip the .zip on top of the old installation. There are many new files in bin, lib and tracks directories.

    For new installs, check the ReadMe.txt in the packet or the Youtube videos on how to install the tool

    If you have any questions, let me know.

    Enjoy, and get faster.

    The Telemetry Tool updated to 10.6.

    The new version is at https://www.racedepartment.com/downloads/telemetry-tool-for-acc.34563/

    With this version I updated the JRE to version 15. So if you are updating, you need to
    - update the bin directory (there is also for Linux and Mac a custom JRE binary included)
    - update the lib directory
    - update the Telemetry.jar + the .bat (windows) and .sh files (linux/mac)

    Key new features
    • Support for ACC driver swap. This feature has been tested, but not extensively. Any feedback is welcome
    • Added Statistics table, which will show much more driving statistics on per lap basis
    • Added Launcher, which you can use instead of the several per game .bat files. The runWin.bat (and runLinux.sh and runMac.sh) have been updated to start the launcher. You can still use the per game .bat files to start the Tool, if you prefer that.
    • Added to UDP forward option to send the data out in F1 2020 format for all supported games, including ACC. You can use this e.g. with Thrustmaster SF1000 wheel to get data to the wheel's dash, or to send data to other dash, which supports F1 2020 format.
    Other notable ACC related updates/changes.
    • Fixed the "non-realtimeness" of the ACC track position data. Now the tool should show that data as it is in the track, no just update at sector change. This most likely fixed the sometimes odd delta values in race info
    • Fixed issue, where player lap number might be wrong
    • Fixed issue, where laptimes for first lap would be odd in race and causing the "History vs. Me" to be erroneous.
    • The tool should now keep receiving/showing data even if you change driver in endurance racing.
    • Fixed issue, where the first lap would show 0 laptime.
    • Added new system, which will show the Delta also on the last laps after the session time has run out. Also works on time-multiplier races.
    • Fixed random/odd situation, when in some tracks (like Oulton Park), the lap data might not get written.
    New users: In short, unzip the .zip to your system (e.g. to Program Files) or some other place. The start the tool with one of the .bat files (on Windows) or .sh files (on Linux/Mac). The tool will the ask for location of the data etc. Check the ReadMe.txt for details.

    Enjoy, and get faster.

    New version of my telemetry and race strategy tool is here. This is mainly a bug/stability/performance fix with few interesting additions.

    You can get the Tool from https://www.racedepartment.com/downloads/telemetry-tool-for-acc.34563/

    What is new in version 11.1?

    Notable ACC related fix is the UDP Redirect fix. This should also fix issues some people were having with the driver swaps. It also made UDP redirect for the SF1000 to be more stable.

    UDP Redirect
    • Fixed a very nasty random bug, which prevented the UDP redirect to work properly. This fix also improves the performance of the F1 2020 format redirect (ie. the TM SF1000 rim feed).
    • With the UDP Redirect F1 2020 format, the rev lights will blink, if the pit limiter is on.
    • Plenty of smaller fixes/tweaks to the redirect model. This should improve the performance in any game mode, most notably with ACC.
    • Added option to show the map with as transparent background, so if you have only one screen, you could have the map still visible with e.g. the lines driven. See the images below. This does not work on Linux (yet)
    • Made tire core temps to be more prominently displayed. Also moved things bit around
    And many little tweaks/fixes. Check the ReadMe.txt for details.

    For update, update the Telemetry.jar + tracks\ams2 (if you use AMS2) + the .sh files (if you are on Linux/Mac).

    For new install, check the ReadMe.txt file inside the .zip for details on how to install the Tool on Windows, Linux and/or Mac.

    A heads up for those, who are using or plan to use my Tool with driver swaps.

    I have had some endurance racing teams testing my tool, and now there is two ways to make the Telemetry Tool work with driver swaps.

    Simple way is to just UDP forward data from all drivers to one central server using the same IP and Port number. All drivers have to have the ACC Broadcast also working (if driver short names are like D01, D02 or long names like Driver 01, Driver 02, then the broadcasting is not working, and needs to be reset by saving the ACC Settings once). Also for all drivers, disable the 'Automatic Track Detection' via 'Settings' --> 'ACC Settings'. In this mode, the server could also be on driver 1's computer.

    Bit more complex, but maybe bit more robust way is to again have central server, where Driver 1 sends data via normal UDP Redirect. In the central server set UDP port for drivers 2 to driver 5 and then the drivers 2 to driver 5 send data to the corresponding UDP port on the server using the ACC Swap Driver UDP format option. The tool will detect the active driver and use data from that driver. And ACC Broadcast must work for all drivers, otherwise the tool will not detect the active driver. Also for this setting, disable the 'Automatic Track Detection'

    Enjoy, and get faster.

    What is new in version 11.2?

    Notable new additions
    • New trackmaps for new tracks in F1 2021, AMS2 and Kartkraft
    • Statistics table: Added wing setup data
    • HTTP Server output:
      • Fixed deltaToLeader in the json/aidata
      • Made JSON/tracks to output track list for the current game
    • + Many little fixes and tweaks
    See the ReadMe.txt for details

    For update: Copy Telemetry.jar + the tracks directories content to your current installation. The changes are in AMS2, F1 and KartKraft directories.

    For new install: Check the ReadMe.txt for the installation instructions. In short, just unzip to somewhere on you system, either to 'Program files' or somewhere else. Now you don't need to anymore edit the baseSettings.xml, as the tool will create it automatically.

    Enjoy, and get faster!
