Welcome

Welcome to the FreeEMS wiki, where free means freedom, and open source means open for anyone to read.

FreeEMS is a free Engine Management System. It includes both software and hardware designs for the experimental engine. Have you ever thought that an engine could run better than when it was manufactured, but haven't been able to make a prototype because it was too large of a task for you to accomplish? Or perhaps you want to do something special at the race track or on a closed stage. If so then this is the project for you. Here you will find downloads of software / firmware to run on a hardware system. The design files for the hardware system are also posted here. More information can be found at diyefi web page
