Lap Legend telemetry analysis — free, in your browser

LapLift reads Lap Legend app exports and turns them into a full analysis session — the racing line, corner G, a delta against faster drivers and auto-synced video. Export the CSV and upload it.

Files LapLift accepts

CSV export
A Lap Legend app CSV — the export that opens with “# Lap Legend CSV Data Export” and a metadata header. Keep the exported filename, which carries the session date and time.

What gets parsed

Speed (GPS)GPS positionHeadingAltitudeLateral GLongitudinal GVertical GYaw rateThrottleBrake pressureSteering angleRPM

Lap Legend pairs a GPS/IMU source (commonly a RaceBox Mini) with an optional OBD/CAN bridge. GPS, G-forces and yaw rate are always there; throttle (accelerator pedal), brake, steering and RPM — plus engine temps — appear when the OBD bridge was connected.

What you can do

Overlay a faster driver
Stack your lap on top of any lap shared with you. A time-delta trace shows exactly where you gain and lose, corner by corner.
See your line and corner speeds
Your GPS trace becomes a track map with the speed you carried through every corner, so you can see where the time really goes.
Auto-sync your video
One click lines GoPro or DJI footage up with your data. Scrub the trace and the video follows, frame-accurate — no nudging footage by hand.
Build a Theoretical Best lap
LapLift stitches your fastest sectors into one ideal lap, so you know what the session was actually worth.
See how you stack up
Compare against other drivers on the same track with crowd percentiles — where you rank overall and corner by corner.

Questions

What does LapLift read from Lap Legend?

The app's CSV export — GPS speed and position, heading, altitude, the vehicle-aligned G-forces and yaw rate, plus throttle, brake, steering and RPM when the OBD bridge was connected.

Do I need an OBD bridge for LapLift to work?

No. Without it you still get GPS, the racing line, corner G and yaw. With it you also get pedal inputs, steering and RPM.

My Lap Legend file has no date — will that matter?

Lap Legend puts the date and time in the filename, so keep the exported name (in the form YYYYMMDD-HHMMSS-…) and LapLift reads the session time from it.

Is it free?

Yes. Create an account, upload your Lap Legend CSV, and analyze it in your browser at no cost.

Free, in your browser. Nothing to install.
