If anyone is interested, here is the source code for speeduino [1], megaSquirt [2] and rusEFI [3], two comparable open source ECUs.<p>[1] <a href="https://github.com/noisymime/speeduino/" rel="nofollow">https://github.com/noisymime/speeduino/</a><p>[2] <a href="https://github.com/onesk/ms3-source" rel="nofollow">https://github.com/onesk/ms3-source</a><p>[3] <a href="https://github.com/rusefi/rusefi" rel="nofollow">https://github.com/rusefi/rusefi</a>
Nice to see another option in this space. I shall have to come back to this when it comes time to resume on various engine-related projects I have on backlog.<p>A question for any of you more familiar with this project: Does it support MAF sensors for measuring intake air? Or is this purely a speed-density system? Scanning the documentation, I see mention of different MAP sensors, but a search finds nothing for MAF sensors. If this is presently only a speed-density system, is support for mass airflow on the roadmap, or this intended to remain only a speed-density system?
> Ever wondered why black box, aftermarket engine management systems can cost thousands of dollars?<p>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.<p>It’s cool they released this as open-source but the tech would have been novel circa 1992.
While I love that this is possible you have to be very literate in electronics for this to make sense. A lot of car guys just aren't going to rip apart their wiring harnesses and do testing to make sure it'll work with their onboard sensors. That being said I'm currently looking into this for a turbo econobox. Haven't decided whether to go this route or a standalone but I still have plenty of time to source parts.
I've been looking at EFI options for a 427 ci stroker Windsor build so this is very interesting to me, but I'm curious really how much effort it would be to put together a working system for this vs. just buying something like a Holley Sniper EFI.
This is really neat!
About 13 years ago (when I was a late teen) I was really keen on the whole engine management idea, and tried to wrap my head around megasquirt.
Today I'm running diesel lumps from the late 70's (Land Rovers) so can't really use this even tho it would be really cool. Makes me want to get a small petrol engine from a scrapyard to play around with this.<p>A note: took me a little too figure out which MCU this is build around. Surely it couldn't be the classical AVR arduino, but yes, it's a ATMega 2560.
This is neat, I've been daydreaming about this being possible to make for years now. Practical? Probably not, hard to beat a multi million dollar budget, but still, neat.
I've been looking into this for my Miata. There are a few plug and play options for hardware that you can buy from small companies. This is all platform dependent of course.

This is super cool. Much like the Raspberry Pi, I could see this as a way for non-developers to start getting interested in FOSS software/hardware hacking.
Am I supposed to already know what "engine management" means by the time I click on this? I get that it has something to do with car engines, but ...?
