RaceBox telemetry analysis — free, in your browser

LapLift turns a RaceBox session export into full lap analysis — the racing line, corner speeds, a delta trace against faster drivers and auto-synced video. Upload the CSV and go.

Files LapLift accepts

RaceBox CSV export
A CSV exported from the RaceBox app. Both the standard session export and the “Track Session” export read; LapLift finds laps from the file's own lap markers.

What gets parsed

Speed (GPS)GPS positionHeadingAltitudeLateral GLongitudinal GVertical GYaw rateThrottleBrakeRPM

RaceBox is a GPS + IMU unit, so speed, position, G-forces and yaw rate come straight from the device. Throttle, brake and RPM only appear if you logged them through the RaceBox OBD-II add-on.

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

Which RaceBox export should I upload?

Either — the standard RaceBox CSV or the “Track Session” CSV. LapLift detects laps from the file's own lap markers, so both work.

Does LapLift show throttle and RPM from my RaceBox?

Only if you recorded them through the RaceBox OBD-II add-on. GPS speed, position, G-forces and yaw rate come from the RaceBox itself on every session.

Is a RaceBox good enough for real analysis?

For lap work LapLift treats it like any other logger — you get speed, the racing line, corner G, a delta against other drivers and auto-synced video from a RaceBox session just like an AiM or MoTeC one.

Is it free?

Yes. Create an account, upload your RaceBox session, and analyze it in your browser at no cost.
