Feature Comparison Overview

The table below was intended to provide a quick glance at what we can currently do today, while comparing it to similar products. This table is not a complete feature table, it was designed to highlight the most important requirements by potential users. If you need something we don’t have please post about it here.

*  means this is a shared resource, ** denotes a different shared resource etc. For example if you have a 4 cylinder engine with sequential fueling(cam and crank triggers) that leaves you with 6 channels to use for either ignition or speed input via LibreEMS or only 2 channels via FreeEMS-vanilla.
