Export your lap data to MoTeC i2, VBO, KML and GPX
Your session should not be locked inside one app. VlastLap exports to the four formats serious analysis actually uses, including MoTeC i2 that most phone apps skip.
Four real export formats, one phone
VlastLap records 100 Hz telemetry by fusing your phone IMU with GPS, then lets you take that data anywhere. Every session can be exported to four formats, each built for a different job:
- MoTeC i2 — the analysis standard in pro and club motorsport. Channel overlays, math channels, lap-vs-lap and full data zoom. This is where engineers and fast amateurs live.
- VBO (Circuit Tools) — the native format for VBOX Circuit Tools, widely used for track-day analysis, line comparison and video sync.
- KML (Google Earth) — drop your laps onto satellite imagery to see the real racing line and your exact track-out points in 3D.
- GPX — the universal GPS format. Opens almost everywhere, easy to archive, share or feed into other tools.
The honest gap: most phone apps do not do MoTeC i2
This is the part worth knowing before you pick an app. MoTeC i2 export is a recurring request on the forums of even the best mobile lap timers, and many of them still do not offer it.
RaceChrono Pro is excellent and very reliable at 19.99 € as a one-time purchase, but it does not export to MoTeC i2. To get pro analysis files, you typically end up on dedicated hardware and its own software (AiM RaceStudio, VBOX, MoTeC loggers), which is a different budget entirely.
VlastLap gives you MoTeC i2 export at app pricing, from the phone you already carry. That is the whole point: pro-format output without buying a logger first.
Format to tool to job
| Format | Opens in | Best for |
|---|---|---|
| MoTeC i2 | MoTeC i2 / i2 Pro | Deep channel analysis, math channels, engineer-grade lap study |
| VBO | VBOX Circuit Tools | Track-day analysis, line comparison, video sync |
| KML | Google Earth | Seeing the racing line on satellite imagery in 3D |
| GPX | Almost everything | Universal sharing, archiving, importing into other tools |
Pick the format your workflow already speaks. The data underneath is the same fused 100 Hz session.
What you are actually exporting
Each file carries the session VlastLap built from sensor fusion, not raw GPS samples: a 100 Hz stream that tracks real GPS to within about 3 to 4 km/h on speed, with the racing line smoothed offline for analysis. On top of speed and position you get longitudinal and lateral g, and, if you connect an ELM327 adapter, 16 OBD-II parameters such as RPM, throttle and temperatures.
Be clear-eyed about what this is: phone fusion at 100 Hz, not a dedicated 25 Hz multi-constellation GNSS logger and not homologated transponder timing. For absolute position accuracy, that is what the upcoming VlastLap hardware (Anchor, Halo) is for. For immediate, lag-free telemetry from the device in your pocket, and clean export into the tools you already use, this is it.
