What this mod does

ACTI (Assetto Corsa Telemetry Interface) is a telemetry tool by KLGreene. It consists of a standalone program and a small in-game app that together give you live access to the car’s data and log it in the format used by MoTeC i2, a motorsport data analysis program.

What it does

  • Logs telemetry to log files compatible with MoTeC i2.
  • Shows live data in workspaces you can configure.
  • Allows remote access: a friend or teammate can view or log your data in real time from anywhere while you drive.
  • Lets you control from the game when data acquisition starts and stops with the acti trigger control app.

What’s in the package

It includes the acti client, the in-game control app, a MoTeC i2 installer (the supported version is 1.0.21.30) and a sample MoTeC project with the data channels Assetto Corsa provides.

Version

Version 1.1.2 was released alongside Assetto Corsa 1.16.1 and added new channels, including extra KERS data. Version 1.1.1 had added track status channels. It’s a tool for anyone who wants to seriously analyze braking, racing lines and setups, or work with a data engineer in leagues and teams.
