Dragy & VBOX telemetry analysis — free, in your browser

LapLift reads the Racelogic VBO format that both Dragy and Racelogic VBOX export, and turns a GPS session into full lap analysis — the racing line, corner speeds and a delta against faster drivers. Upload the .vbo and go.

Files LapLift accepts

.vbo (Racelogic VBO)
The Racelogic VBO text format — the file Dragy exports, and the same container Racelogic VBOX units write. LapLift reads any .vbo that has the standard time, latitude, longitude and velocity columns.

What gets parsed

Speed (GPS)GPS positionHeadingAltitudeSatellitesLateral G (derived)Longitudinal G (derived)Yaw rate (derived)

Dragy and VBOX are GPS devices, so LapLift computes cornering G and yaw rate from the speed-and-heading trace rather than a physical accelerometer. Any extra columns your .vbo carries — from a VBOX with analog or CAN inputs — come through as additional channels.

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

Can LapLift open a .vbo file?

Yes — upload the .vbo directly. LapLift reads the Racelogic VBO format that both Dragy and Racelogic VBOX export, as long as it has the standard time, latitude, longitude and velocity columns.

Does LapLift show G-forces from a Dragy?

Dragy is a GPS device, so LapLift derives lateral and longitudinal G and yaw rate from GPS speed and heading. They are computed, not read from an accelerometer.

Will my VBOX's extra channels come through?

Any additional columns in the .vbo — analog or CAN inputs a VBOX recorded — are plotted as extra channels alongside speed and the map.

How are laps found?

From the start/finish line. LapLift uses the track's known start/finish gate where it has one, and otherwise finds the repeated crossing point in your GPS trace.

Is it free?

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