# rusEFI Feature Status

WARNING this page is PARTIALLY out-of-date!!! <https://github.com/rusefi/rusefi_documentation/issues/261>

**Update: 26Mar2023 changes are WIP with the goal to have current features correcly represented!**
This document should evolve into a table-of-contents (TOC) for rusEFI features (see <https://github.com/rusefi/rusefi_documentation/issues/459>

The layout here is based on the rusEFI Online (REO) navigation menu.
Links to the overall rusEFI project pages have been retained for ease of quick access to the relevant TunerStudio view.

Color code meanings:-  
(&#x1F49A;): **_OK to use_** - Working, tested and no ongoing work  
(&#x1F536;): **_Use at own risk_** - Believed working, may have bugs or has ongoing work  
(&#x1F534;): **_Do not use_** - Not working or potential of damage from testing
