Quick Start

Get Braking Lab Capture running and capturing your first telemetry from iRacing or LMU in under 5 minutes.

This guide walks you through installing Capture and getting your first telemetry data synced to the web app.

Requirements

Before you begin, make sure you have:

  • Windows 10 or later (64-bit)
  • iRacing and/or Le Mans Ultimate installed
  • A Braking Lab account — create one if you haven’t already

Installation

  1. Download the Capture installer (.msi)
  2. Run the installer and follow the setup wizard
  3. Launch Braking Lab Capture from the Start menu

First Launch: Onboarding

When you open Capture for the first time, the onboarding wizard guides you through setup:

Step 1: Welcome

You’ll see a brief overview of what Capture does and how it works.

Step 2: Sign In

Sign in with your Braking Lab account using the device code flow:

  1. Capture shows a verification code
  2. A browser window opens to the sign-in page
  3. Enter the code and authorize Capture
  4. The app confirms you’re signed in

Step 3: Simulator Detection

Capture checks your simulator installations:

  • iRacing: Verifies that the telemetry folder exists and checks if Automatic Telemetry is enabled (see iRacing Setup)
  • Le Mans Ultimate: Detects the LMU telemetry directory automatically — no manual setup needed (see LMU Setup)

Step 4: Existing Files

If you have existing telemetry files (.ibt for iRacing, .duckdb for LMU), Capture offers import options:

  • Number of files found and estimated lap count
  • Import period — Choose to import files from the last 7, 30, or 90 days
  • Skip for now — You can always import later from the File Manager

Step 5: Automation Preferences

Configure how Capture handles new files:

  • Auto-process — Automatically parse new telemetry files as they appear
  • Auto-sync — Automatically upload processed data to the cloud

Both are recommended for a hands-free experience.

Your First Session

Once setup is complete:

  1. Start iRacing or LMU and enter a practice session
  2. Drive some laps — Capture monitors for new telemetry in the background
  3. End the session — The simulator writes the telemetry file (.ibt for iRacing, .duckdb for LMU)
  4. Capture detects it — The file appears in the status display
  5. Processing begins — Braking zones and lap data are extracted
  6. Sync completes — Data uploads to your Braking Lab account
  7. Open the web app — Your laps appear in My Laps

The whole process happens automatically if you enabled auto-process and auto-sync during onboarding.

Verifying It Works

After your first session, confirm everything is connected:

  • In Capture: Check the session status shows your track, car, and lap count
  • In Capture: The file status should progress from New → Processing → Ready → Synced
  • In the web app: Go to My Laps and look for your imported session
