Highlights

UltraLog now opens RaceChrono track sessions. Export a session from RaceChrono or RaceChrono Pro as CSV v3 and drop it straight into UltraLog — your GPS trace, phone sensors, and OBD/CAN channels land on one synchronized timeline, with lap numbers and the GPS Track Map working out of the box. Analyze your track days on a big screen instead of a phone.

This one came straight from a user request: a RaceChrono user asked whether UltraLog could read their lap-timing exports and shared a full 2.5-hour, 125 MB session from a track day to test against. That real session — 515,000 rows, 34 channels, six recording fragments — now parses in under half a second. Thank you for the data; real files are what make format support solid.

New: RaceChrono CSV v3 imports

  • Everything on one timeline. RaceChrono merges GPS (position, speed, bearing, altitude, fix quality), phone sensors (accelerometer, gyroscope, magnetometer, lean angle), and any OBD-II/CAN channels you logged (RPM, oil temperature, throttle, …) into one table — UltraLog reads it all.
  • The Track Map just works. Latitude/longitude arrive in decimal degrees under their standard names, so the v2.13.0 GPS Track Map appears automatically: the circuit drawn beside your chart, laps detected, any channel painted onto the racing line.
  • Lap and fragment aware. RaceChrono sessions that were paused and resumed at the track record multiple fragments, and the in-file elapsed time resets at each one. UltraLog builds its time axis from the GPS timestamps instead, so the whole day stays in order. Lap numbers come along as a channel.
  • Duplicate channels stay distinguishable. RaceChrono logs some channels once per source — you'll see speed (gps) next to speed (calc) so you can compare the GPS speed against RaceChrono's calculated one.
  • Resilient parsing. Sessions survive an Excel/Numbers/Sheets round-trip (trailing-comma padding is handled), a malformed row is skipped rather than failing the file, and temperatures exported as .C display as °C.
  • Clear guidance on the wrong export. Only CSV v3 is supported — pick it in RaceChrono's export dialog. Loading a CSV v1/v2 export shows a clear "re-export as CSV v3" message instead of a confusing failure, and .vbo/.rcz are not supported.

Improved: unit preferences now cover more source units

Channels logged in °C, °F, m/s, or meters now honor your display unit preferences — previously they were shown as logged regardless of your settings. This applies to RaceChrono's GPS speed (m/s) and altitude (m), and to the °C temperatures written by the AiM, ECUMaster, Emerald, MHD, RomRaider, and Woolich parsers. Meters follow the short-distance convention: the metric preference keeps meters, the miles preference shows feet — so GPS altitude never displays as 0.003 mi.

Documentation catch-up

  • The Supported ECU Formats wiki gained full pages for RaceChrono plus the five formats that shipped without one: MHD Tuning, BlueDriver, Motorsport Electronics, DynamicEFI, and Locomotive — and its auto-detection list now covers all 15 formats.
  • README and ultralog.co now list the complete format roster.

Under the hood

  • Fixed a fixture path casing bug that had been silently skipping the RomRaider and OBDLink example-file tests on Linux CI — they run (and pass) again.
  • A RaceChrono file missing its Format metadata line now reports exactly that, instead of an unsupported-version error.

Installation

macOS

  1. Download the appropriate .dmg file for your Mac:
    • Intel Mac: ultralog-macos-intel.dmg
    • Apple Silicon (M1/M2/M3/M4): ultralog-macos-arm64.dmg
  2. Open the DMG and drag UltraLog to your Applications folder
  3. Launch UltraLog from Applications. The app is signed and notarized by Apple, so it opens without a Gatekeeper warning.

Windows

  1. Download ultralog-windows.zip
  2. Extract the zip file
  3. Run ultralog-windows.exe

Linux

  1. Download ultralog-linux.tar.gz
  2. Extract: tar -xzf ultralog-linux.tar.gz
  3. Run: ./ultralog-linux
