How to Use Prediction Tools

Getting Started

Select your Bike Class and Ambient Temperature in the global controls bar — these apply to both tools. Hit Get Weather to auto-fill ambient temp from your location or a ZIP code.

Engine Temp Tool

Tape Strips: Reflective tape strips cover the radiator and oil cooler. More strips = less airflow = higher temps.

Log a Session: Click the green ＋ Log Session button in the Sessions table to enter session data in a modal form.

Predictions: Once you have 2+ sessions, enter tape counts in the Predict section to see predicted temps, adjusted for ambient temperature.

Adaptive Model: With 3 sessions it fits a linear model; 4+ sessions may upgrade to quadratic or cubic if the data warrants it (R² threshold).

Physics-Informed: Ambient temp uses a fixed coefficient (0.4 °C per °F deviation from 70°F) to prevent sign-flip with small datasets.

Tape Recommendation: The app back-calculates which tape count is predicted to hit your target temps.

Tire Pressure Tool

Log a Session: Click the green ＋ Log Session button to log ambient, track temp, tire compounds, start temps, start PSI, and avg race PSI.

Compound Effect: Different Dunlop compounds have different pressure-rise rates built into the model.

Predictions: Enter your planned setup and the model predicts average race PSI for front and rear.

Bar ↔ PSI: 1 bar = 14.504 PSI. Seed data is pre-loaded in PSI already.

Weather Integration

Click Get Weather to open the weather tool. Grant location permission for automatic coordinates, or enter a ZIP code.

Choose Current, Past (historical), or Future (forecast) to fetch the temperature at any date/time.

The fetched temperature auto-fills the Ambient Temp field.

Backup & Import

Backup: Downloads a JSON file with all your sessions (built-in seed data excluded).

Import: Load a previously exported JSON to restore sessions on another device.

Data is stored locally in your browser (localStorage). Clearing browser data will erase it.

Tips

The more sessions you log, the more accurate predictions become.

Predictions are per-class — Supersport and Superbike data are kept separate.

Built-in seed sessions (marked "Built-in") are excluded from exports and cannot be deleted.
