Track Attack telemetry analysis — free, in your browser

LapLift reads Track Attack CSV exports and turns them into full lap analysis — 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 Track Attack app CSV export — tab-separated, with “Start Date” and “Lap Number” columns.

What gets parsed

Speed (GPS)GPS positionHeadingLateral GLongitudinal GRPMYaw rate (derived)

The file interleaves GPS, acceleration and distance at different rates; LapLift merges them onto one distance grid. Track Attack doesn't log yaw directly, so LapLift derives yaw rate from GPS heading. RPM appears when your setup recorded it.

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 export does LapLift accept from Track Attack?

The Track Attack CSV export (tab-delimited). Upload it directly.

Where does the yaw rate come from?

Track Attack doesn't log yaw directly, so LapLift computes it from GPS heading — enough to drive the understeer/oversteer balance view.

Does RPM come through?

Yes, when your Track Attack session recorded it. GPS speed, position, heading and lateral/longitudinal G are always read.

Is it free?

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

Free, in your browser. Nothing to install.
