MoTeC i2 is professional data-analysis software from real motorsport, with fully configurable workspaces and custom maths channels, and it reads logs that a sim or a separate logger has written. Flowix records Automobilista 2, Assetto Corsa, Assetto Corsa EVO and RaceRoom laps by itself and analyses them in the browser, trading that configurability for almost no setup.
| Feature | Flowix | MoTeC i2 |
|---|---|---|
| License / price | Every feature free, AI connector included; free limits are 14-day trace storage (7 days for non-clean laps) and 500 MB; lap times and personal bests are kept forever. PRO from $5/month: 1 year, 5 GB, private traces | Free download, no account or cloud; which i2 Pro features unlock depends on the log source |
| Simulators supported | AMS2, AC, AC EVO, RaceRoom | Any sim whose data reaches .ld format: ACC exports it natively, others need a plugin or converter |
| Setup effort | A few minutes: sign up, run the agent, sign in once (AMS2 needs one in-game option) | Install i2 plus a logger or exporter for your sim, then build or import a workspace |
| Background footprint | Native tray agent, 1.3 MB installer, about 5 MB RAM when idle | 15.6 MB i2 Standard installer (measured by us, November 2026); i2 is opened after driving, so the recording footprint is whatever logger you use |
| FPS impact / disk I/O | No window or overlay to render; samples buffered in RAM, one compressed file written per completed lap | Nothing on screen while driving; logging cost depends on the sim or tool writing the .ld file |
| Capture rate | 60 Hz | Set by the sim export or logger |
| Advanced physics channels | Up to 57 channels; full 3-zone tyres, dampers and ride height in AMS2 (fewer in AC and AC EVO) | Whatever the log contains, plus unlimited custom maths channels |
| AI coaching | AI chat over your laps via a free MCP connector (Gemini, local LM Studio, Claude, ChatGPT): ask anything, including one-off calculations | None; you read the graphs and build any extra analysis yourself |
| Sharing | Short link that opens in any browser, with lap overlays | Send the .ld file; the other person needs i2 and a matching workspace |
| Data export formats | CSV and CSVY per lap | Native MoTeC .ld / .ldx logs |
The free plan is not a trial or a cut-down version. Every analysis feature is free, including the AI connector. PRO only changes how long detailed telemetry is stored and who can see it.
Most telemetry tools stop at graphs you interpret yourself, or at tips in a pre-set format: you get the analysis the tool was built to give, and you cannot ask a follow-up. Flowix connects the AI assistant you choose to your laps, so it answers the question you actually have and works out non-standard analysis from your data when you need it.
The AI can run its own calculations on any channel for a one-off question, so you are not limited to built-in reports. Answer quality depends on the model you connect; larger models give better coaching.
How the AI Race Engineer WorksThe Flowix agent is a small native Windows program that sits in the tray, detects a supported sim through shared memory and uploads every finished lap. There is nothing to open after a session: laps are already in your account.
i2 does not record anything itself. Data has to be logged by the sim (ACC writes .ld files natively) or by a community plugin or converter, then opened in i2 on a Windows PC.
Flowix stores a fixed set of up to 57 channels at 60 Hz. Automobilista 2 fills all of them; Assetto Corsa lacks 3-zone tyre and brake temperatures and damper velocity, and AC EVO lacks damper velocity.
i2 shows whatever is in the log at the logged rate, and lets you add your own maths channels, for example custom slip ratios or weighted tyre averages. This flexibility is its biggest strength.
Analysis runs in the browser with lap overlays, 2D/3D track maps, sector splits and leaderboards. The AI connector lets your own assistant query the same data and run custom calculations in plain language.
Analysis runs locally in workspaces of graphs, histograms and scatter plots that you arrange yourself. Results are as deep as your workspace, and sharing means passing files around.
For simple setup and for drivers new to telemetry, Flowix is the easier choice: install the agent, drive, and your laps are ready to analyse in the browser or by asking your AI assistant, with no workspaces or log files to manage.
Advanced racers get the most from using both. Let Flowix record every lap automatically and use its AI-driven analysis to spot where time goes, then open MoTeC i2 to dig into the raw numbers and custom maths channels for the corners that matter. The Flowix agent only reads shared memory, so it runs alongside your MoTeC logger without conflict.
