HotLap — Motorsport Lap Timer & Telemetry for Garmin

Built for the track — and the trail

HotLap is a purpose-built lap timer and data logger for track days, HPDE, autocross, karting, motorcycling and club racing — plus touring on snowmobile, ATV, boat, jet ski or trail.

Position (start/finish line), Distance (auto every set distance), or Manual (tap). Live delta-to-best, predicted lap, best & theoretical best.

Sectors

3-sector splits

Live S1/S2/S3 deltas versus your best, plus per-lap sector times saved to the activity.

Telemetry

G-force & more

GPS-derived lateral & longitudinal G with maxima, speed, HR, temperature, elevation, SpO2 and respiration.
