Experimental ECU calibration editor and live-data viewer built with Go, Wails, Angular, and Plotly.
Warning
Experimental software. Not validated for vehicle use. Do not flash files produced by FreeBeamer.
Wails hosts the Angular calibration workspace and live-data viewer. The UI provides editable tables, line/heatmap/3D views, undo/redo, diff review, and guarded Save As. Live-data sources and vehicle-profile bindings remain experimental.
Install the Go version in go.mod, Node.js 24, and Wails v2.15.0. On Linux, install the Wails GTK3/WebKitGTK development prerequisites; webkit2_41 is for WebKitGTK 4.1. See the official Wails prerequisites.
