How do you predict cold pressures from real data analysis?

The predictor builds a statistical model from your historical sessions. It analyzes the relationship between cold starting pressures and resulting hot pressures across different tracks, compounds, and conditions. When you input a target hot pressure, the model calculates the cold pressure needed to reach that target based on patterns learned from your actual data.

How does the tool clean and validate incoming data?

The processor automatically filters out unreliable data before training. It detects and excludes: wet condition runs, pre-heated tire runs, aborted laps, pressure bleeds during pit stops, and laps with anomalous length. Sensor spikes in pressure, temperature, and speed data are also removed. This ensures the ML model trains only on clean, representative dry-condition data.

How accurate are the pressure predictions?

Accuracy depends on data quality and quantity. With sufficient historical sessions (typically 5+ per track), predictions typically fall within 0.02-0.05 bar of actual results. The system provides confidence intervals showing prediction reliability and warns when data is insufficient for reliable predictions.

What telemetry formats are supported?

The predictor accepts telemetry exports as ZIP archives or linked folders containing CSV files organized by track folder. Supported formats: WinTax4, WinDarab, and MoTeC, with auto-detection. Linked folders auto-scan when you switch pairs and are remembered across sessions.

Does it work with vehicles without TPMS or when using tire heaters?

Yes. For vehicles without TPMS or when using tire heaters/blankets, you can use the Tire Pressure Logs in the Session Logs tab to manually record cold/hot pressure pairs, track compounds, and calculate K-factor regression per wheel. The built-in pressure calculator uses the OptimumG gas law formula to recommend cold pressures.

How does the linked folder workflow work?

Instead of creating ZIP archives, you can link a CSV folder directly. The app auto-scans the folder contents when you switch vehicle/tire pairs. Linked folders are remembered across sessions, and you can drag and drop folders onto the app. Especially convenient for teams exporting telemetry to a shared network folder.

How does Session Logs verification work?

Every prediction can be saved with metadata (driver, event, session, tire condition, notes) and filtered by track, driver, date, or event type. After the session, add actual hot pressures and the system compares predictions vs reality with color-coded accuracy feedback. Expandable bleed coefficient columns show per-wheel expansion ratio R for each entry.

What data do I need?

Telemetry exports (ZIP or linked folder from WinTAX4, WinDarab, MoTeC). More sessions = better predictions.

How does the Run Filter work?

The Run Filter is an interactive scatter plot showing training runs by ambient temperature (x-axis) and best lap time (y-axis). Drag to select a region, or use step arrows for ±0.5°C and ±0.5s precision. Only selected runs feed into the prediction — exclude outlier sessions or match race-day conditions. Runs Summary Stats below the filter show per-run details, a laps histogram (green = enough laps, amber = fewer), and a warning when your target laps exceed available data.

How do temperature corrections work?

When current conditions differ from your training data, the predictor applies up to three corrections using the OptimumG gas law formula: (1) ambient temperature change (ΔT.Amb), (2) track surface temperature change (ΔT.Track), and (3) tire setup temperature — when tires are pressurized at a different temperature than ambient (T.Tires@Press). Each correction shows per-wheel pressure deltas. A color-coded bar indicates how large the temperature difference is.

How does the bleed correction work?

The bleed correction uses an exponential pressure build-up model fitted to your telemetry. Per-wheel expansion ratios (R = P_hot / P_cold) are computed from real data. Set race laps and formation laps — the system calculates R at the formation lap point and the bleed needed per wheel. Three modes: Constant Bleed (set desired bleed, get start pressure), Custom Start Pressure (set grid pressures, get expected bleed), and Grid Pressure (enter measured pressures from a practice grid simulation).

Can I transfer pressure data between tracks?

Yes. The Track Relations Matrix generates cross-track coefficients that let you transfer pressure knowledge between circuits. It uses bilinear interpolation within the data range and linear extrapolation outside it, providing reliable starting points even for tracks with limited data.

Does it work for long runs vs qualifying?

Yes. Training runs (qualifying, practice) feed the ML model for cold pressure prediction. Long runs and race stints are handled by Tire Pressure Logs, which tracks stabilized pressures and calculates K-factors per wheel.

What is Plateau Detection?

Plateau Detection automatically identifies when tire pressures have stabilized during a run (reached 97% of total build-up). These stabilized runs are auto-saved to your Session Logs as verified baselines, giving you reliable reference data without manual work.

Can I use it without TPMS?

Yes. If you record pressures manually (pre-session cold, post-session hot), you can use the Tire Pressure Logs in the Session Logs tab to track compounds, calculate K-factors, and get cold pressure recommendations.

What is Tire Pressure Logs?

Tire Pressure Logs lets you track tire compounds, build ΔP vs ΔT charts with trend lines, and auto-calculate K-factor regression per wheel. It includes a pressure calculator with OptimumG gas law formula for hot/cold conversion. Free-text cells with autocomplete and autosave.
