Live timing & track map

Watch your friends
race, live.

A live track map and a broadcast-grade timing tower for the people you race with in iRacing. Put it on the TV, keep Discord in the corner, and follow every lap they run — while they are running it.

If you race, you need the app — it reads iRacing and broadcasts your session. If you are just watching, the browser is all you need.

What it does

Everything the timing screen has — for everyone you race with.

The map, the tower, the sectors and the flags. Yours and theirs, at the same time, on whatever screen is nearest.

A live track map

Every car as a moving dot on the circuit. Positions arrive fifteen times a second and are extrapolated between frames, so the dots glide instead of stepping.

Standings and gaps

Position, car number, driver, last lap and the gap to the leader — tabular figures, fixed rows, nothing jumping as the digits change. Switch to the relative and it reorders to whoever is physically nearest you on track, you in the middle.

Sector times

Purple for a session best, green for a personal best, yellow for anything slower — on sectors and on the lap. The same language a broadcast uses.

Fuel and pit stops

Burn per lap, laps of fuel left, and how much you need to reach the end — for your own car. Who is in the pits right now, for everyone.

Flags that mean something

Track flags across the top; black flags and meatballs on the driver's own row, so you can see at a glance who has one.

Built for a room

One slider scales the whole interface — type, rows, panels and all — so the tower is still readable from the sofa on the other side of the room.

Your friends

See who is out, right now.

A friends list that knows who is in a session. Somebody fires up iRacing and they light up; click them and you are watching their race from the first corner. Close the sim and they go dark again.

Your group is whoever holds the invite link — the kind you paste into Discord, because that is where this group actually talks. There is no public directory and nothing to browse.

Several at once

Three friends. Three races. One screen.

Nobody schedules their races around anybody else. Watch every session your friends are in side by side, and open the one that gets interesting.

Read it at a glance

Colour that means exactly one thing.

Broadcast graphics stay near-monochrome until something happens. Then the colour is not decoration — it is the information. Pitwall holds to that everywhere a number can change.

Sectors

Four blocks a lap, each one filling as the car crosses the line.

Purple — fastest anyone has gone
Green — their own best
Yellow — slower than that

The colours in the tower above are computed, not painted. They mean what they say.

Fuel

Burn per lap, what is left, and what the finish needs.

In the tank27.4 L
Per lap2.61 L
Laps left in it10.5
Laps to the flag11

Fuel is your own car only. iRacing does not publish anybody else's, and Pitwall will not guess it.

Flags

Track flags across the top of the stage; personal flags on the driver's own row.

Green Yellow White Blue Meatball Black Chequered

On a TV across a room, a yellow you have to hunt for is a yellow you missed.

How it works

One small app on the driver's PC. Nothing on yours.

Worth being straight about, because it is the one thing that shapes everything else.

The driver's PC iRacing shared memory 60 Hz, that machine's session only Pitwall agent reads it, sends 15 frames a second Relay One in, many out Your browser nothing installed The TV in the corner same page, bigger type The desktop app works with no account at all
Why an agent at all? iRacing has no live API for a session you are not in. Results appear after the session ends; the only real-time source is the sim's own shared memory, on the machine it is running on. So somebody's PC has to push the data out — there is no other route. Everything in Pitwall follows from that one fact.

Racing? Download the app

Windows. It reads iRacing and broadcasts your session, then gets out of the way. It keeps itself up to date — when there is a new version it says so and updates when you say yes.

Just watching? Open the site

Nothing to install, nothing to configure. Click a friend who is out and you are watching them.

Where it runs

On the TV, in a tab, or on its own.

The same view runs in a browser and in the desktop app, so nobody has to install anything to join in. Turn the interface scale up and it reads from the far side of the room; leave it on the TV and it picks a session up on its own, without anybody getting off the sofa to click something.

The desktop app also carries its own relay, which is the interesting part: on a LAN, or with no internet and no account at all, it still shows you your own session. That is the offline mode — not a degraded fallback, a supported way to run it.

Honest about the edges

Things Pitwall does not do, so nobody arrives expecting them:

No results history or championship tables. No setups, no telemetry analysis, no coaching. No phone app and no VR overlay. Fuel is your own car only. And a friend who is not running the agent is a friend you cannot see — unless they happen to be in your session, in which case iRacing has already told your own PC where they are.

Privacy

Only your friends. Only when you drive.

Your position is visible to people you have added, and only while a session is actually running. There is no public list and nothing to browse — the friends list you see is only the people you share a group with. Close the sim and the telemetry stops immediately; you stay in your friends' list the way anyone does in a chat app, shown as offline.
