Strategy that plays the result
Plans are ranked by projected finishing position and championship points, not just elapsed time. Undercut maths accounts for cold-tyre out-laps, and it will not recommend a plan that finishes the race disqualified.
For F1 26 on PS5
A race engineer that actually reads your telemetry.
Pit Wall listens to the UDP feed from your console, runs the strategy, tyre and corner maths locally on your PC, and talks to you over the radio while you drive. Every number it says is measured — never guessed by a language model.
One-time payment. One computer. No subscription.
Watch it make a real call
Hungaroring, sixteen laps left, running fourth on old hards with a quicker car three seconds behind. Box and lose the position, or stay out and defend? Everything below is the running application: telemetry arriving over UDP, the strategy engine doing the maths, and the engineer's own voice answering questions asked over the radio. No dialogue was written for this video.
Turn the sound on — the engineer's answers are spoken by the app's own voice. The race is synthetic, generated as genuine F1 2026 packet structures and sent to the real receiver; the software reading them is not.
What it does
Pit Wall reads all 24 cars from every packet, not just yours, so a question about a rival is answered with that rival's data.
Radio you can talk to
Ask for the gap, a rival's last two laps, or what changes the call. Say the wake word or use a button. It can be interrupted mid-sentence, and it remembers standing instructions across sessions.
Calls you didn't ask for
Rival pit stops as they happen, a car behind closing over a rolling window, safety-car delta breaches, damage, and power-unit wear heading for a grid penalty.
Corner coaching with numbers
Not "brake later" but "brake 8 metres later while protecting apex speed" — measured against your own personal best, with differences below the noise floor left unsaid.
Sessions you can reopen
Recorded sessions replay without the game running. Compare two laps distance-aligned, see where the time actually went, and keep a permanent history of every stint.
A connection screen that tells the truth
It separates "the socket is open" from "real telemetry is arriving", recommends the right LAN address for your console, and names the actual bind conflict when something else owns the port.
The part that matters
Most "AI" tools hand your telemetry to a language model and hope. Pit Wall does the opposite: deterministic code computes every number, and the model is only allowed to say them out loud.
That split is the whole design. A model that invents a lap time sounds exactly as confident as one that read it, and mid-race you cannot tell the difference. So the model never sees raw telemetry to interpret — it receives computed results from an allow-listed set of tools and narrates them.
Common questions never reach a model at all. Gaps, tyre temperatures, damage and strategy status are answered locally, which is why they come back instantly and cost nothing.
Your data stays on your PC. The database, the raw 60 Hz traces and your Windows username are never uploaded. Only compact situation summaries go out, and only for questions that genuinely need judgement.
# where each request goes
Exact telemetry / commands → local, deterministic
Unsolicited radio calls → local, deterministic
Normal interpretation → model, low reasoning
Strategy / setup / what-if → model, high reasoning
# the model can only call allow-listed
# tools, with validated arguments and a
# bounded number of rounds. it has no
# filesystem, shell, network or database
# access of any kind.
Every screen
Real captures from a running build. The race is synthetic; the software is not.
What you need
- F1 26 on PS5, with UDP telemetry set to format 2026.
- A Windows 10 or 11 PC on the same home network as the console.
- An OpenAI API key of your own. You paste it once when the app first starts.
- A microphone and speakers, if you want to talk to it. Everything else works without them.
The API key is billed by OpenAI, not by me
Pit Wall costs $20 once. The engineer's voice and reasoning run on your own OpenAI account, so those calls appear on your OpenAI bill. Most questions are answered locally and cost nothing at all, but a long race with heavy radio use will run up a small charge. You set your own spending limits on the OpenAI dashboard.
macOS is not ready yet
Pit Wall is Windows-only today. The macOS build is in progress; it is not sold or promised here until it exists and has been tested on real hardware.

Get Pit Wall
Paid by Venmo, sent by hand. It is a one-person operation, so codes are emailed personally rather than issued by a robot.
$20
once — not a subscription
-
Send $20 on Venmo to @scott-v-sv. Put the email address you want the code sent to in the payment note.
-
Get your activation code by email. Usually within a day — it is sent by a person, not automatically. If it has been longer than that, email vale.scott00@gmail.com.
-
Install and enter the code once. It activates on that computer and then runs offline. You will also be asked for your OpenAI API key on the same screen.
One code activates one computer. Reinstalling on the same machine is fine and does not use it up. Moving to a new PC needs a new code — email me if a machine died and I will sort it out.
Already have a code?
Enter it to download the installer. The same code activates the app the first time you run it, so keep it to hand.
No code yet? Get one for $20 — it takes a Venmo payment and a reply from me. If you have paid and not heard back, email vale.scott00@gmail.com.
- Download and run the installer. It installs for you only, so Windows will not ask for an administrator password.
- Pit Wall starts by itself at the end of the installer and asks for your activation code and your OpenAI API key. That is the whole setup.
- After that, just open it from the Start Menu or the desktop icon. It goes straight to the dashboard — no code, no setup, ever again.

Questions
Does it work on PC F1 26, or only PS5?
It is built and tested against a PS5 sending UDP telemetry in the 2026 format. The PC version of the game emits the same packets, so it will very likely work, but I have not tested it and will not claim it does. Ask me before buying if that is your setup.
Will it get me banned, or count as cheating?
No. It reads the telemetry stream the game is designed to broadcast, the same one used by overlays, sim dashboards and motion rigs. It never sends inputs to the game and never touches its files.
How much will the OpenAI usage actually cost?
Less than most people expect, because the common questions never reach a model. Gaps, tyre temperatures, damage and strategy status are computed locally and cost nothing. What costs money is open-ended conversation and deep strategy reasoning during a long race. You can cap your spend on the OpenAI dashboard, and Pit Wall keeps working without the radio if the key stops.
What data leaves my computer?
Compact situation summaries and selected computed results, only for questions that need model judgement, and only to OpenAI. The database, the raw 60 Hz trace files, your Windows username and full microphone recordings are never uploaded. Audio clips do go to OpenAI for transcription when cloud voice is enabled.
Do I need to be online?
Once, to activate. After that the app runs offline — telemetry, strategy, analysis and the dashboard all work with no connection. Only the spoken radio needs internet, because that is the part that calls OpenAI.
What happens if I reinstall Windows or change my hardware?
Reinstalling Pit Wall on the same Windows install is fine. A fresh Windows install or a new PC will need a new activation — email me and I will issue one. I would rather do that by hand than build a system that gets it wrong.
Is there a refund?
Yes. If it does not work for you, email within 14 days and I will refund the $20. Please tell me what went wrong — for a one-person project that feedback is worth more than the money.
