Hi everyone. I've been working on my own ECU design as a personal project and wanted to share it with you. Progress has been slow due to many things that I won't go into right now. I'm hoping to pick up where I left off around the new year. It's far more basic than any aftermarket ECU you can buy today, but then of course that's nowhere near as fun.

Let me know what you think. Questions and criticisms welcome of course! Especially from engineers and people familiar with aftermarket ECUs

Re: I made my own ECU
Interesting - I assume you've looked at the megasquirt and diyefi ecus?

Re: I made my own ECU
They both look pretty good and I like the megatunix and tunerstudio software. DIYEFI seems much more friendly and open... Maybe I will contribute some day.

Re: I made my own ECU
Programming, electronics and cars are all fun. This was my way of combining them all

Re: I made my own ECU
That's an ambitious project! Cool 
As per your blog post, for the connector holes that are too small; of they are pth and you feel them out then you may need to solder both the to and bottom sides to maintain connectivity...

Re: I made my own ECU
I ended up making a new board that actually fits the multilock connector. Haven't put it all together yet.. Yeah the pads are pretty small so I will probably end up soldering both sides.

Re: I made my own ECU
Gonna share the code? I wrote a fair bit of good stuff the ms2 with regards to idle code and a few other things. Would be happy to help you if you want. Would even be keen to buy the board and bits from ya and help develop stuff.

Re: I made my own ECU
I haven't decided yet. The code needs a bit of a clean up anyway. Having someone to work with would be awesome.. But I worry that the project will run away from me since I don't get much time to work on it.
I might send you some stuff once I get it into a better state
