Atlas is a free and open ECU calibration suite designed for performance tuning and reverse-engineering of modern vehicles. This project started as an effort to better understand the behavior of the 2022 WRX ECU but, as there is a lack of free and maintained tooling for software engineers and auto enthusiasts to gain first-party access to their ECUs, has since pivoted towards adopting a much broader feature set that encourages modern ECU research, recalibration and modification across increasingly diverse make and model lineups.

- Enables in-depth ECU research and to full recalibration capabilities through an automatic ROM analysis and table match function
- Supports multiple platforms, including Windows, Mac OS X (including M-series), and Linux (including SteamOS and Raspbian), leveraging Java and open-source libraries
- Integrates the Ghidra SRE Framework bundle to analyze tables and emulate ROM machine code
- Supports the Tactrix OpenPort 2.0, OBDLink wireless and wired adapters as well as various ELM327 adapters via direct serial/COM connection with a natively-written driver in Atlas
- Provides 2D and 3D OpenGL visualizations for gauges, tables, and function charts
- Offers a 1-2 dimension table editor with common arithmetic functions for efficient calibration editing
- Includes a live table definition interface to manage project tables and expedite table definition
- Features a value scaling configuration UI to rapidly create new scaling operations as they are identified within ECU logic
- Allows customization of memory parameters to notate ECU RAM offsets corresponding to specific metrics (e.g., RPM, Requested Torque, etc.)
- Provides a simple node graph to create and browse documentation of ECU behavior
- Includes gauges and a data logger for calibration diagnostics and troubleshooting, with project configuration and CSV export capabilities
- Offers a composite project system that consolidates all calibrations and ECU configurations in a single file
- Features an intelligent table-matching system to automatically detect new tables and discover existing tables in unknown variants
- Enables a consistent experience across model years and variants with an intelligent calibration cross-application function
