“Turning while braking — impact leading to loss of control”
Open sessionTyrian
Bringing deeper insights to your existing telemetry. Upload your iRacing IBT files to surface the story hiding in your laps — corner by corner, lap by lap.
Accounts are closed at the moment, so uploads are anonymous: your session gets a link anyone can open. Only the newest 100 anonymous uploads are kept; older ones are deleted automatically.
See it in action
Real sessions, analysed by the same engine your upload goes through. Each map carries the session's heat — where its insights cost the most — and each strip is every lap, in order.

What you get
Upload a lap and Tyrian goes to work — detecting mistakes, scoring corners and laying it all out to explore.
What the analysis finds
Every upload is scored automatically, and overlapping events are grouped into the handful of things that actually happened.
- 23 detectors across eight categories — traction, stability, braking, chassis, track, inputs, racecraft and diagnostics
- Events cluster into insights, so a spin is one thing that happened rather than four separate alarms
- Per-event time-loss estimates, and the three issues worth fixing first ranked ahead of the rest
- Recurring problems told apart from one-offs — trouble on 8 of 12 laps reads differently from a single mistake
How you explore it
One selection drives the map, the lap list and the charts together.
- A chart stack on session time rather than lap distance, so you scroll and zoom straight across lap boundaries
- One row per lap with sector times, deltas and event chips — or switch the same rail to corners, or to an event ladder ranked by cost
- Open any lap into its own drawer, timed corner by corner against your best
- Filter to a kind of event and it highlights on the map, the lap list and the timeline at once
- Deep links that survive reanalysis — lap, corner, viewport, playhead and filter all ride the URL
What's on the picture
Synchronised surfaces that agree with each other.
- GPS track map with corners named outside the circuit, and two lanes of marks — the events, and the insights they group into
- Insight timeline with a narrative lane above the event lane, time / distance / percent axes, zoom, pan and a minimap
- uPlot charts with one cursor across every graph and live readouts
- A delta chart against any reference lap, with a ghost trace of your best
- 21 computed channels — slip, weight transfer, balance and more — plus surface bands read from the sim's own enums
- Drop a video onto the page and it plays in sync with the charts
Sessions and data
The context around the laps, and a way to get your numbers out.
- Pit visits stamped from the sim's own track location — entry, standstill and exit drawn on the charts and as a seam between the laps
- Sector times on every lap, toned against the spread of that session's own laps
- Conditions in the header — sim time of day, sky, wet flag, air and track temperature
- Export a Markdown digest, the whole session as JSON, or lap times as CSV
Known issues
It's early alpha — here's what's rough so you know what to expect.
- Insights still need work — expect rough edges and some calls that miss the mark.
- Sharing is not wired up: you can't make a session public or send anyone a link to one.
- Track map generation can be iffy on incomplete laps (active reset points, out-laps and teleports can distort the outline).
- Event detection thresholds may be too sensitive right now — they're actively being tuned.
