iRacing · Assetto Corsa · Le Mans Ultimate

Your race,
called like a Grand Prix.

A broadcaster calling the action, an engineer on the radio and a spotter watching your mirrors — live, from the moment you leave the pits. Then a coach tells you which corner is costing you the most, and how to take it back.

"Lights out and away we go!"

Real clips, not actors. These are the same voices the engine speaks with in-session — pick a different register for each seat once you're in.

The race team

Four voices.
One race. Yours.

Each has its own register and its own job — and every one of them is watching your car, not a generic broadcast. Three come with the show; the fourth is the one that makes you quicker.

Broadcaster
"Lights out and away we go — and it's three wide into Turn 1, side by side through the Esses!"
Grand-Prix commentary on your overtakes, fastest laps and final-lap drama, in real time. Generated live, so you never hear the same call twice.
Standard and up
Race Engineer
"Box this lap. Fuel to the end plus one — target 1:28.4 and you've got the undercut."
Fuel, gaps, tyres, strategy — called without being asked, and answered when you ask. Press to talk and say it out loud; hands stay on the wheel.
Standard and up
Spotter
"Car left. Car left. … Still there. … Clear. Nice and easy."
Automatic proximity calls so you always know where the traffic is — before it bites. Plus your time, position and gap after every flying lap.
Standard and up
Coach
"Brake ten metres later into six and trail to the apex — that's three tenths right there."
Reads your telemetry against your own best lap and tells you which corner is costing you, in words you can act on next lap.
Pro · between laps Max · mid-corner

The coach is deliberately quiet during a race — you don't want instruction while you're defending a position. It talks in practice, qualifying and testing, and debriefs you after.

Setup King

Your coach fixes you.
Setup King fixes the car.

Four voices watch how you drive. A fifth one reads what you're driving — the actual setup loaded in your garage — and talks to you about it while you're on track.

01
It reads your setup without being asked
Change anything in the garage and the connector picks it up — every spring, bar, damper, pressure and wing the car exposes, plus the air and track temperature you set it under. You don't press anything.
02
It briefs you on the way out of the pits
Roll out and you get about ninety seconds' worth: whether the setup suits the car and the conditions, the one or two things you should expect to feel, and the first change worth trying. Once — not every lap.
03
Then you can argue with it
Hold your push-to-talk key and tell it what the car is doing. It has your actual setup sheet in front of it, so it answers about your car — and it will tell you when it thinks the setup isn't the problem.

"Setup King — the rear's stepping out on exit at turn four."
Setup King
"Agreed — you're on the low side for rear pressure and the track's warmed four degrees since you set it. Try two clicks off the rear bar before you touch the diff. It'll be in My Setups when you get out."
Every exchange is written to the setup's notes, so the reasoning is waiting for you in the garage
It advises — it doesn't touch the car Nothing is written back into the sim. You still make the change yourself in the garage, which means you always know what's on the car and why.
iRacing only, for now It reads the setup iRacing publishes. Assetto Corsa, ACC and Le Mans Ultimate don't expose one, so the other four voices work there and this one doesn't.
Where it lives Max — with in-lap coaching and Drift Mode. It's quiet during a race, like the coach.
Before you subscribe

Which sim you race
changes what you hear.

Voices that talk about the field need a field to read. iRacing and Le Mans Ultimate publish the whole grid. Competizione's named-grid / left-right path is coded and unit-mocked only — never proven in a live ACC session yet. Vanilla Assetto Corsa is still your car only. We'd rather you knew that now than found out on lap one.

Le Mans UltimateFull grid FullFullFullFull
Assetto CorsaYour car only Your laps only — Limited Full
Assetto Corsa CompetizioneUDP path · unit-mocked Named grid when UDP on · unit-mocked L/R geometry · unit-mocked Most · unit-mocked Full

Why: Competizione's Broadcasting UDP named-grid and Spotter L/R cells are unit-mocked / code-present — fixture-proven in CI, never verified in a real ACC session. Do not read the green checkmarks on iRacing/LMU as applying to ACC. When UDP is on, named grid still needs ≥2 cars with real positions; without UDP, names and standings stay dark. Spotter L/R from SHM geometry is the same honesty ceiling — unit-mocked only, not E2E-proven on a real ACC rig, with or without UDP.

iRacing and Le Mans Ultimate still publish the field (full grid), so Broadcaster and Spotter can talk about other cars. Vanilla Assetto Corsa remains your-car-only until UDP Phase 2 — Spotter stays empty; Engineer limited; Coach full. Engineer still needs more than pedals: ACC fuel/tyres/damage → Most; AC inputs → Limited. The engineer no longer calls out cars that aren't actually positioned on the timing screen.

Fair questions

"I already have
a spotter app."

Most serious sim racers do. Here's the honest read on where this is and isn't different.

I use CrewChief — it's free.
And it's excellent at what it does: scripted spotter and engineer calls, from a fixed phrase bank. RealRacer's three show voices cover that ground, generated live rather than sampled, so the commentary is about this race rather than assembled from clips. The real difference is the fourth seat: CrewChief doesn't coach. It won't tell you that Turn 6 is costing you four tenths, or what to change. If all you want is "car left", keep CrewChief — it's genuinely good, and free.
I use a telemetry tool already.
Then you have the numbers and you're doing the interpretation yourself. This is the other half: the analysis arrives as a sentence, out loud, between laps — which corner, how much, what to change. Your laps, deltas and ghosts still live here too, so you can go and read the trace when you want to. It's a coach on top of telemetry, not a replacement for it.
Do I need to buy anything?
No. A lightweight Windows connector reads your sim's telemetry locally and streams it up — nothing on your wheel, no capture card, no second PC. The overlay is a browser source in OBS. If you also drive at a real circuit, your phone is the device there; a RaceBox Mini is optional and only adds 25 Hz slip and friction.
Broadcast-grade HUD

A stream overlay
that looks like Sunday TV.

A clean, corner-anchored in-cockpit HUD — live delta, sectors, predicted lap — that drops into OBS as a browser source. Readable over any footage, built for the broadcast.

Your chat can hear the race.

The race team's audio plus the on-screen HUD turn a quiet practice session into appointment viewing. No green screen, no second PC — one browser source and you're live.

The bridge

And if you ever
drive the real thing.

What the coach learns about you here doesn't stay here. Your sim weaknesses become the brief before a real track day, and your real laps come back as a ghost you can chase in the sim. Same engine, same coach, same voice. Nothing else crosses that line.
