Files LapLift accepts

CSV export
A TrackAddict (HP Tuners) CSV — the RaceRender-style export that opens with a “# RaceRender Data: TrackAddict” header.

What gets parsed

Speed (GPS)GPS positionHeadingLongitudinal GLateral GVertical GBrake (on/off)

TrackAddict is a phone app, so telemetry is GPS plus the phone's accelerometer. Turn on TrackAddict's Vehicle Calibration so the accelerometer axes read as car forward/lateral/vertical. The standard export has no yaw-rate, RPM or throttle channel; brake comes through as a calculated on/off trace when present.

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 a TrackAddict file?

GPS speed and position, heading, and the phone's accelerometer (longitudinal, lateral and vertical G), plus a calculated brake trace if the file has one.

Does it show RPM or throttle?

TrackAddict's standard export is GPS plus phone motion, so there is no RPM or throttle channel to read. You still get speed, the racing line, corner G, a delta against other drivers and video sync.

Should I turn on Vehicle Calibration in TrackAddict?

Yes — with it enabled the accelerometer axes line up with the car (forward / lateral / vertical), which is what LapLift expects.

Is it free?

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