# Engine Configs This directory contains pre-defined configurations for popular engines. These configurations are a convenience, not a limit. Most engine types can be manually configured. In TunerStudio or rusEFI console use the "Popular Vehicles" dialog to apply one of these presets. See https://github.com/rusefi/rusefi/wiki/Engine-Types This folder is also used by the continuous integration testing suite. New configurations should follow the pattern of _.cpp for consistency. A future change may rename these to _.cpp
