What Is Racing Lab?
Racing Lab is an AI sim racing coach integrated into Pit House. Its goal is to help beginner drivers make progress in practice and give more experienced drivers new insights for improving lap times. We present the AI’s driving behavior, the user’s own driving performance, and the differences between the two in a more intuitive way, so players can clearly understand where they can improve.
The main features of Racing Lab include:
- Viewing the AI’s optimal racing line;
- Viewing the AI’s throttle, brake, steering, and gear references;
- Performing real-time comparisons while driving;
- Allowing the AI to directly take control of the car;
- Recording your own practice data;
- Comparing your trajectory, throttle, brake, speed, and gear data with AI data through charts after a practice session.
Who Is Racing Lab For?
Beginner sim racers
If you are new to sim racing, you may run into problems such as:
- Not knowing when to brake;
- Not knowing when to start turning or how much steering input to apply;
- Understanding the in-game driving assist line, but still struggling to drive well yourself.
Racing Lab helps you understand how a track should be driven more intuitively through real-time assisted control.
Users who want to improve lap times systematically
If you can already complete laps consistently but want to further improve your lap times, Racing Lab can help you compare more details.
You can view the difference between your driving trajectory and the AI trajectory, and you can also compare throttle, brake, speed, and gear curves. Compared with practicing purely by feel, data comparison helps you understand more clearly where your driving differs from the AI reference drive.
Technical Principles Behind Racing Lab
Racing Lab currently uses a self-trained AI driving model based on reinforcement learning.
The AI learns how to drive specific track and vehicle combinations, then generates corresponding reference data for racing line, throttle, brake, steering, and gear. During practice, users can compare their own driving performance with these AI reference data in real time or after the session. Because only a small number of manual constraints are added during the training process, and no real human driving data is imported as the AI’s reference, some AI inputs may appear unreasonable. However, the overall lap time is fast.
AI Driving Control: Driving Data Presented Through Haptic Feedback
One important feature of Racing Lab is that it not only displays AI data, but can also let the AI take control of the vehicle during personal practice to demonstrate how to drive.
When AI Driving Control is active, Racing Lab can control the MOZA wheelbase to turn the steering wheel and can also control the mBooster Active Pedals. Users can observe, through real hardware, how the AI brakes, turns, and accelerates out of corners, making it easier to understand the driving rhythm.
Core Features Currently Supported
Real-time AI control reference
The real-time Racing Lab overlay can display key AI driving control references, including:
- Throttle;
- Brake;
- Steering;
- Gear;
- Trajectory.
Users can observe the AI reference data while driving and compare it with their own actual inputs. You do not need to be a telemetry analysis expert to understand the differences between yourself and the AI through these intuitive data.
This feature backs up the original files, supports one-click restoration of the original racing line, and does not affect game file integrity verification. Currently, in-game racing line file replacement is supported only in Assetto Corsa.
AI Driving Control
After meeting the hardware and firmware requirements, users can turn on the main AI Driving switch in the top-right corner of the AI Driving Assistant page in Racing Lab, allowing the AI to control the vehicle during personal practice.
AI Driving Control supports:
- Controlling the MOZA wheelbase to turn the steering wheel;
- Controlling the mBooster Active Pedals;
- AI driving demonstrations in personal practice mode only.
Telemetry recording and post-session comparison
Racing Lab currently supports recording users’ practice telemetry data. After a practice session, it compares the user data with AI data through charts.
Initial Support Scope

Hardware and Firmware Requirements
To use Racing Lab properly, users need to meet the following requirements.
Software version
- Pit House: version 1.3.8 or later.
Firmware versions
- Wheelbase firmware: version 1.2.9 or later;
- mBooster pedal firmware: version 1.2.7 or later;
- Mechanical pedal firmware: version 1.2.5 or later.
Hardware connection
- A MOZA wheelbase must be connected;
- At least two MOZA pedals must be connected;
- The two pedals are used for in-game throttle and brake;
- Mechanical pedals must be connected to the wheelbase instead of directly to the PC;
- Third-party pedals are not supported.
Racing Lab requires at least two MOZA pedals because AI Driving needs to control both throttle and brake. This allows users to switch more conveniently between AI control and manual control without rebinding axes in the game.
If the hardware connection does not meet the requirements, the Racing Lab program title bar will display an unsupported status.
Game Telemetry Configuration
Under normal circumstances, telemetry for Assetto Corsa and Assetto Corsa Competizione is automatically configured by Pit House.
If the data in the real-time overlay does not change as the car progresses through a lap in the game, you can first check whether game telemetry has been configured.
You can check it as follows:
- Open the Pit House home page;
- Find Assetto Corsa or Assetto Corsa Competizione in the game list on the right;
- Check whether the “Configured” badge is displayed;
- If “Configured” is not displayed, click Configure.
If telemetry has been configured but the overlay still does not display AI data, continue checking the following:
- Whether the corresponding AI data resources have been downloaded;
- Whether the current track and vehicle combination is within the officially supported scope.
Current Limitations and Notes
Racing Lab is still under continuous iteration. For a more stable experience, please note the following limitations before use.
AI Driving can only be used in personal practice
AI Driving is intended only for personal practice and demonstration. It is not allowed in multiplayer mode.
When Racing Lab detects that the user is in multiplayer mode, it disables the AI driving feature.
In human-AI shared control, the AI may not be able to recover from severe loss of control
In certain human-AI shared control scenarios, such as when the user controls throttle and brake while the AI controls steering, or when the user controls steering while the AI controls throttle and brake, the vehicle may crash into a wall, spin, or go too far beyond the track limits if the user’s inputs exceed what the AI can manage.
In such cases, the AI may not be able to recover from the loss of control, and the user will need to manually restart the session.
The AI does not support driving out of the pit lane
In the current version, AI Driving supports only on-track driving. It does not support automatically driving out of the pit lane, nor does it support route planning within the pit area.
This is because the current version is mainly trained around on-track driving scenarios, and pit area map data has not yet been collected.
Vehicle setup changes may affect AI performance
AI reference data is generated based on officially supported tracks, vehicles, and configurations. If the user significantly changes vehicle setup or settings, AI driving performance and reference data may differ from the actual vehicle state.
Tracks and vehicles outside the supported scope are not available yet
If the current track or vehicle is not within the officially supported scope, the following situations may occur:
- AI Driving cannot be enabled;
- The overlay cannot display AI references;
- No practice record will be generated in Pit House after the lap is completed;
- The Racing Lab program title bar displays the corresponding prompt.

Future Roadmap
In the future, we will continue expanding Racing Lab around the goal of “helping users improve their driving skills more effectively.”
More precise performance analysis
Racing Lab will continue improving its driving performance analysis capabilities, including more precise corner-by-corner performance analysis, clearer identification of time loss sources, brake release smoothness analysis, steering input analysis, and beginner-friendly training suggestions that are easier to understand.
The goal is to let users not only see “what is different,” but also understand more clearly “what should be practiced next.”
A stronger community atmosphere
Racing Lab will add leaderboard features in the future, allowing users to compare performance under the same track and vehicle combinations.
We hope this will motivate users with clearer practice goals and make lap-time improvement more engaging.
More considerate training assistance
Racing Lab will also add training plan features in the future, helping users practice continuously around specific tracks, vehicles, and driving issues.
Compared with one-off practice records, training plans can help users build a longer-term path for improvement.
Broader game support
In the future, Racing Lab will continue expanding support for more games, tracks, and vehicles.
