AI Summary

Co-driver is a free, private telemetry dashboard for Forza Horizon 6. It reads the data your game already broadcasts, turns it into a second-screen dashboard showing real-time tire grip, suspension movement, and driving inputs, then stores your laps so you can replay them, compare two runs, and build car setups with confidence. Everything stays on your own machine — no cloud accounts, no leaderboards, just you and your data.

How It Works

1
🎮 You love racing games

You've been playing Forza Horizon and want to get faster, not just feel faster.

2
📺 You prop up your phone as a second screen

You find a cool dashboard app someone made that reads data directly from your game.

3
⚡ Everything lights up the moment you start driving

Four corner panels show your tires working in real-time, a big circle shows how much grip you have, and a timer ticks alongside your best lap.

4
🔁 You finish a lap and watch it back

After your run, you scrub through the replay frame by frame and see exactly where you braked too late or got on the throttle too early.

5
You decide what to tune
⚙️
Tweak your setup

You adjust your suspension and tire pressure, drive again, and watch the graphs change to see if it helped.

🏁
Keep chasing the lap

You ignore the setup for now and focus purely on driving lines and trail-braking points to shave off time.

6
📊 You compare two laps side by side

You pick your fastest lap and a recent one, and the app shows you exactly where you gained or lost time along the track.

🏆 Your best lap finally breaks

You've got a clear picture of what's working, what the car can do, and where to push next. All on your own screen, private, no subscriptions.

What is co-driver?

Co-driver is a self-hosted telemetry workspace for Forza Horizon 6. It listens to the UDP data stream that the game already broadcasts, then renders it as a live dashboard, hotlap timer, dyno chart, and tune workbench. You run it on a laptop or mini PC next to your TV, point your game at it, and get a second-screen view of every corner's suspension, tire temperatures, slip angles, and damper motion in real time. The stack is TypeScript with Nuxt on the frontend and a Nitro server handling the UDP listener and WebSocket fan-out to the browser.

Why is it gaining traction?

The hook is that Forza already emits this data -- most players just never see it. Co-driver makes the invisible visible: a live G-G plot showing how round your traction circle really is, trail-braking automatically flagged on the input trace, and a dyno that builds itself as you drive. The auto-baseline tune generator is the standout feature -- it takes your current build and produces an FH6-correct starting point, adapting to your upgrades. No accounts, no cloud, no leaderboards. Everything stays on your machine.

Who should use this?

Forza Horizon players who want to tune their cars seriously. If you've ever wondered whether your dampers are actually working or whether your brake bias is causing understeer, this gives you the data to answer that. Track day enthusiasts who want real telemetry without buying dedicated hardware. Tuners who want to compare laps side-by-side and see exactly what changed between setups. Not for casual players -- the interface assumes you know what slip angle and damper velocity mean.

Verdict

At 10 stars with a 1.0% credibility score, co-driver is early and unproven -- the README says as much. That said, the feature set is genuinely useful, Docker deployment is one command, and the built-in manual pages show the creator understands the domain. If you're a Forza tuner who wants to stop guessing and start measuring, it's worth a look. Just expect rough edges and small breaking changes as it matures.
