Building the Speeduino Standalone ECU - Against the Clock

You should try : 1 conformal coating 2. Solder the Arduino Mega directly to the main board 3. Design & 3dprint an enclosure for your hardware with gasket, proper mounting of the connectors on the enclosure even have your own logo on the case

As a fellow car enthusiast (on a budget) and IT guy, this is exactly what I want. I do a lot of tinkering with SBC's, mainly Raspberry Pi's, and your previous video pointed me in the direction of Speeduino and I'm already planning my build. Better yet, being Australian, it's local for me too!

I'm overwhelmed by this whole thing but this is the only way for the car I have without spending more than I bought the car for so I'd appreciate all the help

A budget standalone ecu is the holy grail!

I have been wanting to build a stand alone ecu for years now. I have experience with arduino and soldering. Thank you for making the videos. Information like this helps make it easier to get into a project like this.

just sorted out getting my speeduino dropbear because of all these videos, currently getting reliability on my 1987 205gti with a big spec and swapping twin 45s to throttle bodies.

This is a complete game changer for engines like the 1ZZ, which had previously not been economically viable to tune, thanks to the exorbitant price of standalone ECU's, as you could just do a 2ZZ swap for the same money. But now good 2ZZ's are getting thin on the ground, and you can get 3 or 4 1ZZ's for the same price.. well, this just opens them up to all sorts of modifications. Hayabusa throttle bodies, and forced induction spring instantly to mind. Bloody marvelous :-)

I have a couple of Motorhomes, both near the same YM, one is powered by a 350 and the other is as far as I can tell, a 427 industrial or truck version, both Chevy engines both are running Qjets at the moment. Ok so I have a 3rd BBC which I have dumped a $^*t load of money in and still have to dump more into it, it's a 540 which will be a race rig if I live long enough. Anyhow, for the 540 project, I dumped another load of funds into a MS3X with everything needed to run 2 stage fuel and 2 stage N20. COP, SFPI, dual knock sense, RTCC, 2 low impedence injector driver boards, a GPIO for controlling a 4L80E, there's absolutely NO room left in the case for anything else even if DIY made anything else that could be installed. So now I have to spend more for the full version, not a problem, I expected that. Then there is the MSQ file that must be developed, that's a problem for me at this time, I'm going to need some serious support for that. Again, anyhow, I knew a little ( very little and still very little) about Speeduino before starting the MS3X system and now I want to have a go at this to convert both or at least the BBC powered Motorhome first. IMOP I'm thinking this would be a good deal for either engine. Any opinions to offer from anyone?

I have a Speeduino ECU that I will be putting in a Honda Civic ECU case for a auto trans. I will be using the OEM harness on my 97 Honda Civic Coupe manual with the plug for the trans control being used for my waste gate control solenoids and more.

I'm running a speeduino n02c board on my turbo mx5. Great ecu. Has all the features I need for a turbo road car.

I just received my Speeduino board, now I just need to order up the parts to populate it. Thanks for posting this one.

This eventually will be our only option, since the EPA is making it illegal for companies to sell stand alone ECUs and piggyback ones, we will have to make our on, so the earlier you hop on this wagon, the better off you will be, thanks for sharing bro

Amazing to see more love for the speeduino project. There are many variants of Speeduino Compatible ECU's also. Josh allowing this to be an open source project has empowered some of us to make our own. For me it started as refining the project for my own car. This gained traction and I now design and sell my own Speeduino Compatible variants.

I've been waiting for someone to vouch for speeduino. This is the push i need. cheers!

Initially I was going to fit some throttle bodies from a zx6r to my 1982 kz1100. After some thinking and the accidental acquisition of a turbo, I’m leaning towards using a single throttle body, thinking the inlet size matched to the compressor size. I’m not 100% on the wiring or programming but I figure I’ll just take it 1 step at a time.

This is the best thing i have ever seen. will be building one for my turbo d16 project.

Thank you so much for introducing this ecu to me, I am working on boosting a 08 scion tc right now and this ecu has solved my issue with not wanting to spend 1k or more on another standalone and it makes this dream now possible for me. This was my first car and decided I wanted to keep and have the best time I could with it.

This is the most well presented speeduino channel I’ve run across! I subscribed after your last video and I’ll probably get a speeduino because of you! Thank you for putting these videos together and I hope your having a good one.

Very encouraging. I'm gonna tackle my K24 😃 soon!

That cheap one is completely fine. That 12mHz osc is for the ch340g USB chip. The actual XTAL for the 2560 is pins 33 34 and uses a much smaller footprint osc.
