The Lebois Racing

17/05/2026

It's been a while since we've shared any content for contributors, so I wanted to give you the roadmap for the coming months to show you that there's some serious work in the works:

SRT V10 GEARBOX:

I've been working on version 1.4 of the Config Center (RC9 firmware) for a while now. It will bring many improvements:

Support for the LedPanel mod with pin selection

Improved preload adjustment with the ability to test the clutch with a slider that simulates the clutch pedal

New, quieter servo

Much more integrated documentation, including schematics and annotated PCB views

It's currently in beta testing with a small group who are providing a lot of feedback, and I thank them. That's also why it's taking a while... as long as they find problems or ideas for improvements, it keeps progressing.

In any case, this v1.4 is a significant step forward in terms of ease of use and will allow you to get even more out of this amazing box.

COMPETITION CONTROL BOX:

The V2.0 firmware is also currently being tested. I've reworked the motor control to increase the control frequency (which partly determines the motor speed) from 52kHz to 82kHz. In practical terms, the difference is so significant that we have to limit certain effects that can become quite aggressive.

And this is just the beginning.

ON THE WEBSITE:

I'm currently testing 3D visualization modules. You can see one at the beginning of the TractionLoss documentation:

For the moment, I don't find it particularly practical; I hope to find a better solution.

THE STORE:

A major undertaking recently was migrating the store to a new hosting provider with a new theme. This resolved the bugs some users were experiencing and, most importantly, made the site faster.

It's not the prettiest website in the world, but at least it's functional. You'll find the same products at the same prices!

IN THE MEANTIME:

I'm offering contributors the Fanatec power supply mount I designed (next post). It's also available on Cults: https://cults3d.com/:4447917

Thank you all for your support! It's difficult these days to find the time to advance projects, and even more difficult to find time to ride, but the passion and motivation remain the same thanks to you!

🔧 Patreon Update

Over the past few months, Lebois Racing projects have evolved a lot:
new firmware releases, development of the Config Center, support improvements, documentation, hardware testing…

In order to keep developing, maintaining, and improving everything in good conditions, I’ve decided to slightly adjust the Patreon pricing for new subscribers.

👉Important: current supporters will of course keep their existing price❤️

This change helps ensure:

continuous development

better support

more complete and polished tools

Thank you to everyone supporting the project, for free or through Patreon — it’s thanks to you that all of this exists 🙏

Concretely: the PRO tier is going from €5 to €8.

Yes, €8 gives you instant access to 6 years of work — not too bad, right?

Firmware Update — RC7 for the SRT V10

Today I’m posting the RC7 firmware release for the SRT V10.

The full changelog is long, but the main highlights are:

eClutch fix for PCB v1.3

Added handbrake support (enable, calibration, live value display)

Added button plate button visualization to make key mapping easier

Known issue: Button 4 stays pressed on PCB v1.3

Next Major Improvements

Upcoming big updates:

In the Button Plate tab, functions will be displayed instead of raw numbers, using a dropdown list

For the eClutch, I will progressively add installation photos

More generally: more links to the relevant documentation throughout the Config Center

Major milestone in the development of the SRT V10 gearbox: I’m working on a dedicated software !

The SRT V10 Config Center will allow you to configure the gearbox and also debug it, without needing to flash the gearbox with modified code or enter lines of code in SimHub. Everything is designed to make testing and fine-tuning settings easy.

For now, this is a beta version that supports the e-clutch, mouse, and button plate mods. The interface will gradually evolve to include as much documentation and troubleshooting as possible, while integrating additional mods over time.

On the firmware side, I’ve worked to keep the V1.2 and V1.3 PCB firmwares as close as possible, so both can continue to be supported in parallel. In fact, I mainly used the V1.2 PCB to develop the software.

I’ll also update the documentation progressively so it reflects the software. The idea, however, is that the documentation will be directly accessible within the software itself—so even if the website isn’t fully up to date, it won’t be a big issue.

The Control Center is included in the firmware archive. You need to update the firmware for the Control Center to communicate with the gearbox, and it’s possible that future Control Center updates will also require a new firmware version. That said, I’ll try whenever possible to evolve the Control Center without touching the firmware, to minimize tedious operations.

As usual, the firmwares are available on this page:
