Open Assetto Corsa Competizione telemetry

Assetto Corsa Competizione exports telemetry as native MoTeC .ld, with its .ldx sidecar, into Documents/Assetto Corsa Competizione/MoTeC. No plugin is needed: you enable it in the car's Electronics screen by setting how many laps to save. Wild Telemetry reads that .ld directly, with no i2 installed.

How to enable it

In the car setup screen, under Electronics, set how many laps you want saved. Every time you drive, ACC exports that many laps; drive more and the last ones are kept.

Upload the .ldx next to the .ld whenever you can: the sidecar carries the lap metadata the importer cross-checks the count against.

The product: FUJI

What you get when you open a session.

Fuji, coloured by how much time changes hands over each 50 m window between lap 15 (2:04.975) and lap 1. Neutral is exactly zero, the scale runs to ±1.12 s, and the 9 corners come from the stored layout.

What it does not do

With no GPS there is no track map until heading-based reconstruction is wired in - documented, not implemented.

No file written by ACC has been decoded in this repository. The claim is that the format is the same, not that it has been tested.
