About rusEFI

rusEFI is an open-source engine management project. It started in 2012 as a software engineer's answer to standalone ECUs that were closed and hard to understand, and the code has been public from the first day.

Today rusEFI sells eight universal ECUs, plug-and-play boards for popular engines and CAN accessories. Every board runs the same firmware, which is developed on GitHub with automated tests and a full change history. Schematics and PCB files for uaEFI and most boards are published too.

The boards are designed by contributors around the world on the Hellen One platform, which builds each ECU from proven blocks — wideband, knock, drive-by-wire — so they come on the board instead of as add-ons.

Help comes from the community: the wiki, the forum, Discord and the Facebook group. Paid one-on-one Technical Support is available separately.

Orders ship from Jersey City, New Jersey. The seller is rusEFI LLC.
