Files LapLift accepts

CSV export (Format 2)
A CSV exported from RaceChrono Pro in its “Format 2” layout — a RaceChrono header block, then the data table.

What gets parsed

Speed (GPS)GPS positionBearingLateral GLongitudinal GYaw rateThrottleBrakeRPM

RaceChrono logs GPS plus your phone's accelerometer and gyro. Throttle, brake and RPM (its “*canbus” channels) come through when RaceChrono was reading them from an OBD-II or CAN adapter.

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 RaceChrono export does LapLift read?

The RaceChrono Pro “Format 2” CSV export. Export a session from the app and upload the CSV.

Do throttle and RPM come through?

If RaceChrono was connected to an OBD-II or CAN adapter, yes — those “*canbus” channels are read. GPS speed, position, G-force and yaw rate come from the phone on every session.

Do I need RaceChrono Pro?

The Format 2 CSV export comes from RaceChrono Pro. Once you have exported the CSV, LapLift does the rest in your browser.

Is it free?
