Talk to your engineer on the radio

Your engineer already talks on his own. This is where he starts answering: hold a wheel button, ask, let go. He replies in his own voice, looking at your race. It takes about 5 minutes. In the pictures, the yellow outline shows where to click.

Before you start, have:
  • Pacedex installed and the engineer already talking. Not yet? Do your first race first.
  • A microphone on the PC: headset, webcam or USB earbuds.
  • A spare button: on your wheel, your controller or the keyboard.
Part 1

Switch on voice questions

One toggle. It ships switched off.

1

Click the gear (Settings), then the Engineer card

The Settings cards with the Engineer card highlighted
2

Turn on Ask by voice during the race

It's in the Talk to your engineer (voice) box. Scroll down a little to find it.

The Talk to your engineer (voice) box with the Ask by voice during the race toggle on and highlighted

Right below sits the Radio button: row, still empty. That's the next part.

Part 2

The radio button

The button you hold to talk, just like a real radio. Pick one you can reach without taking your hands off the wheel.

1

On the Radio button: row, click Wheel

Using something else? Keyboard for a key, Gamepad for an Xbox controller. On console, see the tip at the end of this part.

2

Press the wheel button you picked

You have 8 seconds.

Button set: and its name, for example Wheel · B7.

3

Under Test the radio, click Test. Hold the button and say something

The Test the radio row with Test highlighted and the message All good: button detected and voice captured

All good: button detected and voice captured. If not, the message tells you where it got stuck: the button, the microphone or muted sound.

Wheel not showing up?

  • “No button was pressed”: some wheels have buttons Windows doesn't expose. Use Console button: there the game itself reads the button, so it works with any wheel.
  • Playing on PlayStation or Xbox: in F1, under Settings → Controls, map a UDP Action (1 to 12) to a spare button. Then, out on track, click Console button and press it. The microphone is still the PC's.
Part 3

Who answers

Without doing anything, you already get 20 questions a day free through the Pacedex cloud. Want unlimited? Paste your own AI key. Google's Gemini is free, no card needed.

1

Scroll to the bottom and pick the provider under Provider and model

It's in the Engineer AI (your key) card, right below Talk to your engineer (voice). To start, pick Gemini (Google) — free.

Provider and model with Gemini (Google) — free selected and the How to get your key box

The How to get your key: box with the 3 steps for that provider. Claude and ChatGPT work too.

2

Get the key on the provider's site

Click the link in the box (for Gemini, aistudio.google.com/apikey), sign in and create the key. Copy it.

💡Want screenshots of every screen? Full key guide → Claude and ChatGPT need credit on the API account (the chat subscription doesn’t count).
3

Paste the key into API key and click Save key

The API key row with the key pasted, hidden as dots, and Save key highlighted

The key stays on this PC only. It never goes through Pacedex servers.

4

Click Test

The API key row with the key saved and the message answered in 1.1s

answered in and the time. Under 2 seconds turns green: good for the radio. The box above now says Unlimited — using your own AI key.

Part 4 · optional

A model on your own PC

Running Ollama, LM Studio or another OpenAI-compatible server? The engineer can ask it instead. No key, no limit. Skip this if it means nothing to you.

1

Under Provider and model, pick OpenAI-compatible (your server)

Next to it, type the name of the model you loaded, for example llama3.1:8b.

2

In Server address, paste its address and click Test

For Ollama it's http://localhost:11434. The /v1 is added for you.

OpenAI-compatible (your server) selected, Server address http://localhost:11434 highlighted and the test answered in 0.4s

answered in and the time. Leave the key empty unless your server asks for one.

💡Small models answer fast. On the radio every second counts. A big model leaves your engineer behind the race.
Part 5

The engineer's voice

The same voice he uses for his own calls. Change it whenever you like.

1

In the Neural engineer voice (offline) box, pick the Engineer's voice

Each language has male and female voices. The one you pick downloads once (about 60 MB). With Engineer's language, the radio can speak a different language from the dashboard.

2

Click 🔊 Test

He does a radio check in your headphones. Too fast or too slow? Adjust the Speech speed.

Part 6

Ask on track

Now just drive. Every question uses your race data at that moment: tyres, gaps, fuel, weather and the pit plan.

1

Hold the radio button, ask your question, let go

Talk normally, the way you'd talk to an engineer. For example:

“How many laps have these tyres got left?” · “When do I pit?” · “What's the gap to the car ahead?” · “Is it going to rain?”

2

Hear the answer in your headphones

The live dashboard with the question How many laps have these tyres got left? on the You line and the answer on the Engineer line

It all shows up in writing on the dashboard too: your question on the You line and the answer on the Engineer line.

💡You can follow up: “what if I stretch it two more?” knows you're still talking about the tyres.

No microphone? Ask with a button

In Settings → Shortcuts, the Engineer card has ready-made questions: Situation, When do I pit? and How's the tyre?. Click set and press a button. On track he answers right away. No microphone, no internet.

Something went wrong?

  • I hear nothing: click 🔊 Test in Part 5. Check the Engineer voice volume and, under Radio audio output, the right headphones (or Windows default).
  • I press the button and nothing happens: click Test under Test the radio. Pick the button again (Part 2). Seeing On, but no button.? You haven't picked one yet.
  • “No microphone on this computer”: Pacedex listens through the PC. On console, your headset is plugged into the console. Plug a microphone into the PC.
  • Invalid key or no credit: Test tells you why. Double-check the key on the provider's site. Claude and ChatGPT need credit on the API account.
  • The local model doesn't answer: Nothing answered at that address means the server is off or the address is wrong. Start Ollama (or your server) and check the host and port.
  • He stopped answering: without a key, the day's 20 questions are used up. Paste your own key (Part 3) to go unlimited.

Still stuck? Post a screenshot on our Discord and we'll help.
