SimHub Integration

One API key.
Every lap on the record.

Point SimHub at GTLane and your driving record builds itself — lap times, sector splits, fuel burn, top and average speed, tire compound, plus the car, track, session type and weather it was driven in. No clipboards. No screenshots. No retyping times off the sim screen.

Works with every sim SimHub supports — ACC, iRacing, Automobilista, rFactor, and more.

The problem

Your lap times live
on the sim screen.

You put in a session, climb out, and everything you did stays trapped on the rig — best lap on the in-game leaderboard, sectors lost to a session reset, fuel and tires nowhere on paper. Next time you sit down, none of it is there.

The workarounds are worse. Phone photos of the timing screen. A spreadsheet you update for a week and then abandon. Half the data is missing and the other half is wrong by the time you write it down.

The GTLane SimHub plugin pulls every lap and every session straight from the telemetry your sim is already emitting. Your driving record, stats, and share cards all run off the same source of truth — captured automatically, with nothing for you to do.

What a manual workflow can't do

  • Capture every lap time and sector split automatically
  • Tag invalid laps so they stay out of personal bests
  • Record fuel, top speed, average speed, and tire compound per lap
  • Stamp each session with car, track, type, and weather context
  • Put every stint on your profile in real time
How it works

From the telemetry bus
to your profile.

01

SimHub runs alongside your sim

Drop the GTLane plugin into SimHub on your rig. It listens to the same telemetry SimHub already reads from Assetto Corsa Competizione, iRacing, Automobilista, rFactor, and the rest — no extra game integration needed.

02

Session start fires once

On the first frame of every session GTLane captures the car, track, session type, lap total, and weather. The stint is anchored on your profile before the green light even drops.

03

Each lap streams to your profile

As laps complete, time, sectors, validity, fuel, speed, and tire compound stream up in real time. You watch your history grow live, and your stats update with every lap.

Setup

Plug it in,
start driving.

Seven small steps the first time. After that, every lap you drive streams to GTLane automatically.

  1. 01

    Download the free plugin

    Grab the GTLane plugin from our download page — no account or license key needed for the download itself.

    Download Plugin
  2. 02

    Move plugin to the SimHub folder

    Copy the plugin into your SimHub install directory. SimHub auto-discovers plugins from this folder on next start.

    C:\Program Files (x86)\SimHub

  3. 03

    Restart SimHub

    Close SimHub if it is running and start it again so it picks up the new plugin assembly.

  4. 04

    Enable the plugin in SimHub

    Open the SimHub plugin list and flip the GTLane toggle on. SimHub will load the plugin and show its panel on the next refresh.

  5. 05

    Generate an API key on GTLane

    Sign in to your free GTLane account, head to API keys in your profile, and create one. That key is the only thing the plugin needs to start sending your laps.

  6. 06

    Paste the key into the plugin

    Open the GTLane panel inside SimHub and paste the API key into the field. The plugin stores it locally and reuses it across SimHub restarts.

  7. 07

    Send a Ping to confirm

    Click the Ping button in the plugin. If the response shows your account, the integration is live — laps will stream from your next session.

That's it.

If the Ping response shows your account, the integration is live. Just drive — every lap, sector, fuel reading, top speed, and condition lands on your GTLane profile automatically.

What's included

Everything telemetry
captures for you.

Every lap, every sector

Lap number, total lap time, and sector 1 / 2 / 3 splits stream in from SimHub the moment you cross the line — plus a validity flag so cut laps are tagged and excluded from your personal bests automatically.

Fuel, speed, and tire compound

Fuel burn per lap, top speed, average speed, and the compound the lap was set on. The numbers you actually care about — captured per lap with no clipboard and no manual entry.

Session context, captured once

On the first frame of every session GTLane records the car model and class, the track, the session type, and total or remaining laps. You always know what you drove, where, and in what — independent of whether any lap was completed.

Weather in the data, not your memory

Air temp, road temp, and rain density are stamped onto the session at the start. A 1:42 in the dry and a 1:42 in the wet stop looking like the same lap.

Straight onto your profile

Every stint you drive — laps, sectors, fuel, speed, tires, car, track, conditions — lands on your GTLane profile in real time. Your full history builds itself across every session.

Powers your stats and share cards

The same telemetry feeds your lifetime stats and the share cards you post. Personal bests, optimal laps, and top speeds come from real lap data — not from a screenshot.

Data captured

The full picture,
per lap and per session.

Two layers of data come off your rig — a one-shot session header the moment you load in, and a stream of lap records as each lap completes.

Per lap

  • Lap number
  • Lap time
  • Sector 1 / 2 / 3 splits
  • Valid / invalid flag
  • Fuel used (litres)
  • Top speed (km/h)
  • Average speed (km/h)
  • Tire compound

Per session

  • Game title
  • Car model, ID, and class
  • Track name
  • Session type
  • Total / remaining laps
  • Air and road temperature
  • Rain density
FAQ

Frequently asked questions

Which sims does the SimHub integration support?
Anything SimHub already reads telemetry from. That covers Assetto Corsa, Assetto Corsa Competizione, iRacing, Automobilista 2, rFactor 2, Le Mans Ultimate, RaceRoom, F1, Project CARS, and the rest of the SimHub-supported list. If SimHub can see the telemetry, GTLane can capture it.
What data is captured per lap?
Lap number, lap time, sector 1 / 2 / 3 splits, a valid-or-invalid flag, fuel used in litres, top speed and average speed in km/h, and the tire compound the lap was set on. Each lap is timestamped and tied to the active session.
What data is captured per session?
On the first frame of every session GTLane records the game, car model and class, car ID, track, session type, total laps, remaining laps, air temperature, road temperature, and rain density. That context anchors the stint even if you never finish a clean lap.
Do I need to own a sim racing venue to use this?
No. The SimHub integration works for one driver on one home rig. Sign up free, create an API key, drop the plugin into SimHub, and your personal driving record starts building automatically.
What happens if SimHub or the network drops mid-session?
Laps are buffered locally by the SimHub plugin and synced when the connection returns. A short network blip does not cost you a stint — once SimHub reconnects, the missed laps upload with their original timestamps and slot onto your profile in order.
Do I need a separate license for SimHub?
SimHub itself is free for personal use, so your home rig is covered. GTLane reads the data SimHub already collects, so there is no separate per-rig fee from us for the integration.
