<story><title>Speeduino: Open-Source Engine Management</title><url>https://speeduino.com/home/</url></story><parent_chain></parent_chain><comment><author>asguy</author><text>&amp;gt; Ever wondered why black box, aftermarket engine management systems can cost thousands of dollars?&lt;p&gt;There’s actually a pretty good reason.  I can’t imagine starting a new engine management project in 2020 without using an FPGA to interface with engine positioning sensors and outputs.  Modern engines tend to be way too complicated to coordinate without paying close attention to your modeling of where all the fast moving mechanical bits are currently.&lt;p&gt;It’s cool they released this as open-source but the tech would have been novel circa 1992.</text></comment>
