Two years ago I had too much spare time so I’ve decided to teach myself something new. I am a software developer, was always curious about cars and electronics. I’ve decided to build my own standalone ECU from scratch - the stuff I’ve seen is so not user-friendly that I think there is a place for a nicer, easier to use platform based on modern hardware. Anyway. [ATTACH=CONFIG]33432[/ATTACH] This one has an LCD display on board and there are plans for a small joystick so that one would be able to scroll through the menus etc. There is also integration with the popular Tuner Studio online tuning software. 5 engines have puffed on this so far 🙂 ---

How is this better than Megasquirt feature wise? Also in NY you would only be able to run this on a OBDI car and most people use Megasquirt because of a large feature set(auto tune, anti lag, 2step, etc) ---

5 engines have puffed but none of them were tuned properly. One guy got busy with his health, another guy is too busy to play with all this. That’s the reason I am posting here - I am wondering if maybe someone in the NYC area (I am in downtown Jersey City) would be interested to play with this. I’ve got the software and electronics covered, but I do not hear nor feel cars good enough to tune them properly. The only car which has moved under rusEfi - that’s back in Chicago some time ago: [![](https://canada1.discourse-cdn.com/flex034/uploads/speedlife/original/3X/3/d/3da8dfd7e55334d5b87df656a64dafe5a97a9dfb.jpeg "#rusEfi - standalone engine control unit based on stm32f4") ](https://www.youtube.com/watch?v=M-qqHQ-quFg) Another engine: [![](https://canada1.discourse-cdn.com/flex034/uploads/speedlife/original/3X/0/5/05c3593fdc72572291917012760f7b761f424a12.jpeg "Neon 2 0 on RusEFI") ](https://www.youtube.com/watch?v=VxisTpoe88I) So, maybe someone here would be interested to get involved? - - - Updated - - - > [@LZ](#): > > How is this better than Megasquirt feature wise? Right now this is definitely behind Megasquirt, but The potential advantages over MS: this is GPL open source (older MS used to publish source code but the license was still proprietary), this is based on a modern ARM chip. Modern ARM chip means it’s simpler to write software which should mean it’s easier to build more features. I believe that error reporting and diagnostics could be much more user friendly then it is in current products. But as I said - right now this is a pretty raw project. ---

> [@LZ](#): > > Has anyone tried anything besides a 4 cylinder? Not on a real engine. The firmware is flexible so it does not really matter how many cylinders you’ve got - I think it would control a 13 cylinder engine if you would happen to have one. By the way there is a windows simulator of the firmware. Takes some time to set it up, but once you do you can connect to it with Tuner Studio and rusEfi own console - all without any real hardware: [http://rusefi.com/wiki/index.php?title=Manual:Software:Simulator](http://rusefi.com/wiki/index.php?title=Manual:Software:Simulator) ---

If you ever want to fund the ruseFI project take that Windows simulator and have it emulate OBDII with readiness monitor checks along with VIN selection :lol: ---

> [@LZ](#): > > Has anyone tried anything besides a 4 cylinder? We’ve recently got an inline-6 and a one cylinder running on this, looks like current average is 3.916666 cylinders per vehicle. Just got the fully integrated board running yesterday - finally everything is on the same board, like a real ECU for adults. Still looking for local people to help me tuning all this - need feedback from someone who would know what’s going on with the engine and how these things are done properly.
