   thank you for sharing.
   How many teeth are in the flywheel of this engine?

2. 

   I made one too! Though mine's a lot more primitive! I used the points to sense the crank position. It runs though 🙂 https://www.youtube.com/watch?v=K-y3dsq0RuE

   richtig cooles projekt 🙂

   The website asks me user name & password to enter why ?? please mention another address here .

   Thank you for sharing!
   Your website seems to be messed up, it's asking for a login and password. I'd love to see what you came up with for reading cylinder pressure!

   Thank you for sharing your wisdom.

   Hello, great project, how do you keep EMI at low levels where it doesn't interferes with the atmega microcontroller?

8. 

   Great! Can the arduino adjust the fuel mixture automatically from the oxygen sensor readings?

9. 

   speeduino is the place to start on a project like this is 2019

    analog hybrid pretty impressive

11. 

    any testable improvements?

12. 

    Awesome build man! You were first hit when I searched for arduino fuel injection! Still reading about setup, however wondering why you would use manual trim pots when you have a controller that can do this for you and at a faster and more accurate level based on feedback from engine exhaust and possible exhaust temp? Keep up great work and thnx for great post and info! U ROK!

    seems awfully complex replacement for a set of points and condenser

    my brother is having trouble with the carbs on his dirtbike so we were thinking about doing arduino fuel injection for it! we'll leave the ignition stock for now for simplicity's sake. thanks for the motivation!

15. 

    how does the engine run compared to carbourator? how's the exhaust? is the fuel mixture pretty even? I'm not an environmental freak but I was wondering how more efficient this runs and the differences, it be cool to build something like this for a lawn tractor for fun, I got more than adequate mechanical knowledge but probably inadequate knowledge building arduino devices, pretty awesome you made something like this, and screw the haters calling this pointless, i think its fascinating

    Sir, you have all my respect.

    Thank you for sharing such an incredible project.

    Hi, Im interesting to do an arduino work like this… for a Renault 5 1984, could you share some files or doccumentation about your project. Like de injectors you have used or  the sensor… Greetings 

18. 

    hello!
    you cool idea
    if you is not difficult, send a sketch for Arduino

    Brilliant work. The link to your website appears to no longer work.

20. 

    I'm trying to make the same ! http://brenamanf.wordpress.com/

    maybe you can find something useful …

    How did you made the arduino recognize the lambda?

23. 

    Wow, could we adapt it for an 4 cylinder gasoline engine?

    Hi I am a Electronics Teacher in Brazil, I've been teaching electronics for two years and the first student that I have been able to work with is aptempting to build a project similar to yours, I worked in audio projects in my PHD because I love music and I sugest this work to this student since he is crazy by cars, maily turbo engines, I rather prefer V8s.  But this is another topic.   I think that we will use a old carburated VW AP engine 1.6L from the 1980s.   If you can help us a bit.   He is doing his work as a graduate final course project.   If you could help us with information I would be very greatfull.  It seems that we cannot find many information on ECUs on the internet.  Please send us your email so we can exchange information.  We intent to use arduino as base for the ECU also.

25. 

    great project! is there any reason you decided to go with an op amp based vr conditioner over a dedicated vr chip like an ncv1124? i want to build an arduino based ecu for my 4 cylinder engined car one day…

26. 

    Seems like a whole lota extra junk to break. Whats wrong with the old gravity fed carburetor and magneto. Been working fine for a hundred years now. If it ain't broke, don't fix it.

27. 

    There is more information available on my website, and an example of how accurate the timing is. I managed to achieve about 3 degrees accuracy without much effort, I think 1 degree is quite doable http://scottsnowden.co.uk/?p=320#more-320

28. 

    How precisely do you control timing? 60000000 us / 6000rpm / 360 degree = 27 us for one degree precision. What values are achievable with Arduino?

    I am working on an ECU based on stm32

29. 

    can you show me about your code of arduino plz ?
    Coz. I want to study about this project. I think it's interesting.

    Thanks for the info. I know basic electronics, but am lost at this level of complexity, so I am thinking of trying a mechanical/ electrical set up. Basically a small carbon brush sliding on a circular plate, with a narrow copper strip on it, being driven at crankshaft speed, as it is for a 2 stroke engine.I would be using an injector from a small car engine. I will have to do a sketch and some math to see what the injector duration would work out to be, probably take a miracle for it to work! 🙂

    The electronics aren't too complicated really, they're just in separate boxes. Certainly the fuel injector driver is the simplest part.

    Idle requires a single pulse per revolution (so two pulses per full cycle) of around 1.5 ms, but that's obviously specific to the flow rate of my injector which I'm not sure about – it's pretty oversized.

32. 

    WOW, lots of electronics there!
    Any idea of the injection duration say at idle?

33. 

    I believe this is from a Ford Sierra, but I think mostly they are all very similar from port injected cars. It's just like driving a solenoid.
