Vehicle parameters

Unit system

Vehicle

Kerb mass (kg)(incl. driver + fuel)

Inertia factor(1.05–1.15 typical)

Tyre size— W/A/R format is always metric (industry standard)

Width (mm)(e.g. 225)

Aspect (%)(e.g. 40)

Rim (in)(e.g. 18)

Drivetrain

Gearbox preset

Pull gear(Gear used for the pull)

Gear ratio(e.g. 1.521)

Final drive(e.g. 3.15)

If your log includes a speed channel (mph or km/h), gear ratio and final drive are used only for gear filtering — the inertia method will use the logged speed directly.
