Simulator Controller with AI-based virtual assistants (race engineer and race strategist)

Release 6.8.5 and 6.8.6 (02/06/26)

The release of this week and that of last week include many important fixes, for example for the Spotter, who no longer reports slower cars as being faster in average after a pitstop. Beside that, the calculation of gap times and standings has seen a major overhaul, after we realized that the LMU API reports cars which are in the entry list, but which are not connected to the session.

Release 6.8.7 (02/13/26)



With this release, we're bringing the long-awaited native support for Polish in voice interaction with the Assistants. Thanks to @Przem Lis DTM, all grammars have been translated, and the command reference documentation is also available in Polish. A translation of the user interface is still on our wish list for a future release.

As always, there are also minor other improvements. Details can be found in the Release Notes.

Relase 6.8.8

This time we have significants improvement for the strategy subsystem. Concrete tyre wear data of recent sessions can be used during strategy development to predict stint length, especially for races with a restricted number of tyres. There will be an online session, where I demonstrate the new functionalities on the upcoming Monday evening in our Discord.

Beside that it has become more intuitiv to prepare a race using "Race Settings" for all of you who are not using the more complex settings system in "Session Database".

Release 6.9.0

With this release, we start the implementation for the EA F1 series. Still pretty much a construction site yet and it is required to run Simulator Controller on a separate PC due to the Javelin AntiCheat software, but the next releases will bring more and more functionality to the table.

Beside that, all new cars and track updates of the latest Le Mans Ultimate release as well as several important fixes are included.

Release 6.9.1

The implementation of F1 25 is done, documentation has been added and all tests have passed. However, Javelin is still complaining, so you have to run Simulator Controller on a second machine or in a virtual machine. The following video gives you a brief overview, how to set up a virtual machine to run Simulator Controller on the same machine as F1 25:

As side-effect of the F1 25 implementation, Simulator Controller can now connect to all games on a remote machine incl. consoles which support a UDP-type API. Beside that, we have new and updated car data for Automobilista 2 and many important bug fixes.

Release 6.9.2

We introduce support for the native Anthropic API with this release. This will enable Claude models to be used for Simulator Controller. Claude Haiku is great for rephrasing and general conversation, whereas Claude Opus will shine as backend for the Driving Coach and for complex strategy decisions.

Release 6.9.3

We integrated support for AC EVO this week. Not yet complete, because the API of ACE isn't complete either, but a lot of stuff incl. on-track coaching is already working. Additionally we included a complete overhaul of the spoken command grammars for Portuguese thanks to a great effort of @Jimmy Sant'ana. And, as always, a couple of bug fixes are included as well. Details can be found in the Release Notes.

Release 6.9.5

We have integrated all the data available in the new shared memory API of Le Mans Ultimate, most notably information about TC and ABS activations. This will help the Coach to give you more detailed instructions on the track.

And the revised version of the shared memory API of Assetto Corsa EVO has been integrated as well.

Release 6.9.6

This release contains a very useful improvement for the "Setup Workbench" which now can analyze telemetry data for handling problems and recommend setup changes even after the end of a session. See the short video for a demonstration:

Release 6.9.9

After two technical releases with extensions to the rule engine, we finally introduce some new exciting stuff for the driver. The Engineer now will prevent tyre wear imbalance when it comes to a pitstop. For example, if one tyre on an axle needs to be changed due to excessive wear, the Engineer may decide to swap the second tyre as well to make sure the car shows balanced handling.

Release 7.0.0

Release 7.0 is here and it is huge:

First and foremost for you as a driver, this Release introduces the second part of the new tyre management. The Engineer can now handle multiple different tyre compound mixtures when it comes to pitstop planning. Depending on tyre wear rate, usable tyre life and the remaining number of laps in the next stint, he will pick the best of the available tyre compound mixtures for each wheel. Tyre wear data from the community, if available, may be used here as well (see below).

But that is not all, there are more important changes and additions:

- The community database comes with an all new storage format
- Tyre wear data can now be shared in the community
- Support for a new cloud service for speech synthesis and recognition
- Also support for a new GPT LLM service provider

Be sure to read the Release Notes and the Update Notes, because this Release includes a breaking change, for which you have to update some of your settings in the "Session Database".

Release 7.0.1

The Release of this week is focused on the Driving Coach:

- Several bugs has been fixed.
- Available reference laps from the community can now be loaded automatically and must not be assigned manually by name.
- A lot of new analytical data for the corner performance if provided to the LLM, thereby enabling high end models like GPT 5.5 to come up with even more useful instructions.

Here is a short example with a coaching session using GPT 5.5 (coaching starts around minute 4:00):

Release 7.1.1

Two major additions this week:

• Suspension related issues like bottoming out or swaying can now be handled by the "Setup Workbench".
• The 2026 DLC for F1 25 is now fully supported and the UDP connection can use either protocol version.

Release 7.1.2

This one is all about running large language models locally on your machine. The local LLM Runtime, which can be installed from a DLC, has been rewritten and now supports tool/function calling, which is required to run custom actions by the Assistants. Performance has been improved as well.

Beside that a new function allows you to modify the text returned by an LLM, for example, to remove unwanted test decorations generated by smaller LLMs, which will increase immersion.

Release 7.1.3

Today we introduce automatic detection of bottom out events in the "Setup Workbench".



The function is still under development, not yet tested and calibrated for all simulators, but already working quite well for LMU, ACC, AC and rF2. More is to come with the next release.

The same handling and suspension information is also available to the Driving Coach. See the attached conversation transcript for an example of a discussion with the Coach about handling problems.
