Pit Wall splits condition analysis across two tabs: Thermal for tyres and Environ. for weather and track evolution. Both respect lap scope from Stint analysis.
Thermal view
Open Pit Wall → Thermal tab.
Sections appear only when the recording includes tyre pressure, temperature, wear, and fuel channels. If nothing is available, you’ll see: No thermal analysis data available.
When scoped to a stint, all charts and tables recalculate for those laps only.
Pressure Stabilization
Bar chart per corner (FL, FR, RL, RR) comparing cold vs hot pressures:
| Bar | Meaning |
|---|---|
| Start (grey) | Pressure at stint beginning |
| Stabilized (blue) | Pressure after the tyre heats up |
| Stabilized (amber) | Corner that bled high — lost excessive pressure during heat-up |
Hover a corner for the lap where pressure stabilized and whether it bled high.
How to read it: Large gaps between start and stabilized bars mean aggressive heat-up. One corner consistently amber may need pressure or camber attention — cross-check Tyre Thermal Balance on that corner.
Tyre Thermal Balance
Bar chart of average inner, centre, and outer tread temperatures per corner.
| Element | Meaning |
|---|---|
| Three bars per corner | Heat distribution across the tread |
| Spread (in tooltip) | Difference between hottest and coolest tread zone |
| Diagnostic label (in tooltip) | Plain-language hint (e.g. pressure or camber suggestions) |
Even inner/outer spread often means balanced loading; heavy inner or outer bias can point to camber or pressure tweaks.
Surface → Carcass Recovery
Per corner, how far (in metres) the surface temperature takes to match carcass temperature on the longest straight in scope.
| Field | Meaning |
|---|---|
| Recovery distance | Metres until surface and carcass converge |
| Duct temp | Average brake duct temperature when logged |
Slow recovery on one corner can mean brake ducts are too closed, excessive scrubbing in fast corners, or uneven loading — pair with Chassis → Aero Efficiency on high-speed tracks.
Wear per Fuel Consumed
Line chart per lap: tyre wear divided by fuel used (ΔWear / ΔFuel, in % per kg).
| Trend | Interpretation |
|---|---|
| Flat line | Consistent tyre cost per kg of fuel burned |
| Rising line | Car becomes more tyre-hungry as it lightens — common as fuel burns off |
| Spike on one lap | Possible lockup, slide, or off-track moment — check that lap on Laps table |
Scope to a single stint to see whether wear acceleration happens mid-stint or only after the pit stop.
Environment view
Open Pit Wall → Environ. tab.
Requires track temperature, wind, and related environment channels. Empty state: No environmental data available.
Session Conditions
Full-session timeline (downsampled) vs session % (0–100% through the recording):
| Line | Meaning |
|---|---|
| Track temp (°C) | Rubber/track surface temperature |
| Ambient (°C) | Air temperature when logged (dashed) |
| Wind (km/h) | Wind speed on a secondary axis when logged |
Axes zoom to the data range so gradual changes stay visible — useful for long practice sessions or weather transitions.
How to use: Scan for track temp climbing in the second half — then open Track Evolution vs Pace to see if lap times moved with it.
Track Evolution vs Pace
Per-lap chart in scope:
| Series | Meaning |
|---|---|
| Track temp | Average per lap with min/max band |
| Ambient temp | Per lap when available |
| V-Max | Peak speed that lap (secondary axis) |
Shows whether lap pace and top speed move with track temperature over the session. A faster V-Max on a cooler lap may mean the engine or aero liked the conditions, not just grip.
Wind Sensitivity
Per-lap chart on high-speed sections only:
| Series | Meaning |
|---|---|
| Wind speed (km/h) | Wind during straights |
| Straight speed (km/h) | Speed achieved on those sections |
Helps spot laps where headwind or crosswind may have cost straight-line performance. If wind spikes but straight speed holds, the layout may shield the main straight — compare with Stats → Top Speed.
Lap scope
Selecting a stint on Laps recalculates Thermal and Environment metrics for those laps only. A scope banner appears at the top of the panel with Clear filter.
Inspector charts are not scoped — they always follow Base / Compare lap pickers.
Workflows
| Goal | Steps |
|---|---|
| Diagnose hot tyre on one corner | Scope stint → Pressure Stabilization + Tyre Thermal Balance for that corner |
| Check stint tyre fade | Stint 1 vs Stint 2 → Wear per Fuel trend |
| Understand pace vs weather | Full session → Session Conditions, then Track Evolution vs Pace |
| Explain slow straight | Wind Sensitivity + Stats → Top Speed on the same laps |
