Speeduino standalone engine management has become quite popular recently.
A few people have mentioned it in the forums so I thought let's get one and fit it to my spare Micra.
I'll try and make it as plug and play as possible using all the original sensors.



Fully sequential fuel and spark for £120. Sounds OK to me.

I'll try and do a tutorial on it if anyone is interested.

Assembly of the Speeduino has begun.
Shouldn't take too long, as its not as complex as the Megasquirt I did a few years ago.
You don't need to be particularly adept at soldering with this board it seems.
That's a good thing, as more people could have a go and get themselves a standalone ecu for pennies really.

I'm not going to do a tutorial on building it up, as it's literally just soldering components that are numbered to the board.
Also, this is for a coilpack Micra, not the dizzy one.

Ah right okay I see. Was hoping for a tutorial but I understand if its literally just soldering.
I am on a long waiting list for a standalone so it would be very interesting to see if I can do it myself.
Look forward to seeing more posts :)

OK, maybe some of you would like to know about soldering and how to put components on a pcb. I forget sometimes as I've messed with electronics for 40yrs. If you let me know what you'd like to see/know I can work something out.

I guess you could use it for fueling only
Or possibly if it has coil drivers you could block the distributer hole and use it to run coil on plug

I haven't seen what inputs and outputs it has to say either way

It can run logic coils but not dumb ones that are fitted to the Micra. To run the Micra coilpacks you need bip373's or a Bosch 0 227 100 211 unit like I use.

Ok, so i finished building the Speeduino ecu.





I did a few videos whilst building it, to give you an idea of whats involved.
You can decide if you have the skills needed to do it yourself then.
Yes they're a bit amateur and blurry, but that's the only camera i have at the mo.
Here's a link to the part one, I'll post more links as I edit and upload them.
 
We'll also need one of these to convert the VR crank sensors ac output into a squarewave digital signal.



Oh, and one of these to connect the Speeduino to the Micra.

Just watched the videos from start to finish. Thanks for sharing, I’ve subbed and look forward to more videos :)

I'll upload some more vids today to YouTube. The dual vr conditioner has arrived as you can see from the previous post, so I'll do a vid of fitting that.
I also need to record the firmware and base map loading. Need to get some software on my laptop for that.

I just cut it straight off an ecu. I then straightened the legs and filled it with epoxy to strengthen it.

I cut mine off at the bends and I'm in 2 minds as to whether some of the inboard pins may be too short.

At least the ECUs are cheap, so I can always take a heat gun to another one. I'm using one for a patch harness to hook up my standalone...

It should be OK as long as you have a few mm of pin to solder to.
My Megasquirted Black Micra has a patch harness like you've mentioned. If you scroll back a few pages you can see what I did. This Speeduino Build on my spare car is just for fun and to help ppl out with hopefully a cheaper mapable ecu option.
I'll just be doing a simple jumper lead for this to get it going.

Just making up the jumper lead from the Speeduino to the ecu loom.

Had to dig out the ecu wiring diagrams again. Not used these since fitting my Megasquirt so long ago.

Just had 2 questions if you could answer please, that'd be much appreciated!

Would you recommend testing each component before soldering it onto the board or is the kit you bought pretty reliable?

I noticed you were using the 0.4.4c version. Is there much difference between this and the 0.4.4b version? (I've researched online and can't seem to find the answer).

Thanks :)
 
I'm using the slightly older 0.4.3c board instead of the 0.4.4b. I will have to fit ULN2803a chip in the proto area to give me an additional 4 medium current outputs as I want to use the oem pwm iacv and I'll most probably run out of medium/high current outputs.
The.0.4.4b board already has this modification that's all I think.
As for component quality, they're all OK, you don't need to test any of them.

Thank you for the information :)
 
Finding the videos very useful! Just wondering if there is going to be any more video's on making a plug and play harness or tuning etc?

Thanks :)

Steady on there tiger lol. Yes there are more videos on the way. This isn't my day job, so as and when I have time I'll upload more. The next one will be about the patch harness.

Some more goodies have arrived for the Speeduino install.
Wideband for tuning, Bosch 211 ignitor & connectors to fire the coilpacks and an idc breakout connector block just for ease of connecting Nissans 88 pin connector to the Speeduino.

Been a bit busy at work the last few days so not had chance to carry on the Speeduino standalone ecu build till today.
I've added a ULN2803A chip to the proto area on the board so I can control the fuel pump, radiator fan, output to the rev counter, and have an input for launch control if I choose.
The newer versions already have this I believe.
