Building and Installing a Speeduino Standalone ECU - Turbo Micra Ep.2

In this video, I go through the process of building a V0.3.7 Speeduino Standalone ECU and installing it into the car along with the Wideband AFR Gauge and External Igniter needed to run the coil packs. I also load a base tune onto the ECU using Tunerstudio.
Huge thank you to MegaMicra for creating and sharing the 1.4l base tune that I used in this video.

Awesome! I’ve subscribed to your channel as this is right up my alley lol.

[@shujabeg7625]

This guy has given me the confidence to try this myself

[@the_mintiest_micra]

Happy to hear, good luck👍

[@kafkasbugmusic]

I'm doing a Peugeot 405 with a 406 swap and i'm planning on getting a speeduino, your video is really helpful! And funny too 😅😅 i will keep watchinh the next one!

[@the_mintiest_micra]

Happy to hear, let me know if I you need any help👍

[@izaakramsay4819]

I've had my speeduino and 1.3 march with a TD04, intercooler, custom fuel rail with pink subaru injectors etc ready to go for a year now and I think this is the motivation I needed to actually wire it in.

[@the_mintiest_micra]

It's not too hard of a job to get it set up, would love to see a build like that up and running. Good luck!👍

[@ericsemskar1635]

Always looking forward to another vid

[@2loudspeakers]

Fantastic job!! And great video! You will have an amazing set of skills and experience from all of this. Fair play!

[@Spice-xs4ie]

sick job, cant wait for more

[@gavinearls2935]

cant wait for ep3

[@the_mintiest_micra]

Working on it, should be out soon😁👍

[@micrafamily1432]

Wow fair play that's a lot of work and effort 👌

[@morganwalsh4717]

I really hope ecu works I will love to do this for my micra

[@thephantomarse]

Just subbed nice little project Im building a version 4.0.3 speeduino for my k10 micra i havent decided which engine to put in it yet though

[@sofidaboss725]

Awesome! I was researching Speeduino cause I'm broke and standalone ECUs would cost me my kidney, and came across your channel! Looking forward to ep.3, best of luck, hopefully everything is going according to plan!

[@the_mintiest_micra]

Thanks, mate. I highly suggest you check out some speeduino tutorials if you're thinking of doing something like this. They helped me out a lot. I probably don't explain it very well in this video.😆

[@b1zertoon910]

Currently working on a cg13 most of the problem is with the wiring from ECU non of the sensors are working trying to fix it and built it 🙌🏼

[@the_mintiest_micra]

Unfortunately I'm not too familiar with the earlier distributor engines, I know some of the hardware is different and same with the ECU wiring. There's some info on the forums though. Good luck 👍

[@stephenwalsh8184]

🚘👍👍

[@franz1242]

This is a really interesting project I watched all 5 episodes in a row, but I was wondering how did you make the original speedo and rpm-meter work with speeduino?

[@the_mintiest_micra]

Thanks for the support mate, I can't take credit for getting the tacho working as I just copied what MegaMicra (here on YT) did in his step by step series on his K11 Micra. It really depends on the type of tachometer your car has. For example, I had to add a 1k resistor from a pin related to the crank sensor, I think, on the ECU to the tacho signal wire in the cars wiring loom.

[@franz1242]

@@the_mintiest_micra wow I love how analogic is this mod, unlike some software adjustment or an additional board with fancy PID technology. So well every case is different, I'll learn something by checking MegaMicra but I'm sure it's gonna be a trial-and-error work, i have a lancia Y first generation btw.

[@luukvanoijen7082]

Do you have a wiring diagram? I've got a 1.4 but I hope it's not too different from the 1.0 coilpack engine. I was looking at the MegaMicra videos but the wiring is a bit confusing

[@the_mintiest_micra]

If you hadn't mention you looked at the MegaMicra videos, I would've told you to do exactly that as that's the files I used. 🤣 I have some extra stuff in a shared folder that might help you. I can even try to send you like a voice over walk-through if anything is a bit confusing. Check this folder with the files I used: drive.google.com/drive/folders/1e8W5z4EhZHwW03Oq3Q42SkolCVaGhJ8m DM me on insta if you need any help👍

[@riktanius]

Did you add a VR conditioner to your ecu? I dont see where that would be

[@the_mintiest_micra]

@riktanius Yes, its in the bottom left of the board, higher than the rest of the components.

[@skun80]

Nice! where we can find this ECU? thanks

[@the_mintiest_micra]

There's some places that sell kits depending where you're based. Otherwise, you can buy all the parts yourself, look up Sppeduino ecu kits, and see what version suits you.

[@SeeLikeMe]

Hello my friend i have a big question i want to do the same ecu setup as you i do have a 1.4 and im desperate to figure it out what step did you go through to buy this

[@the_mintiest_micra]

There's a few websites that will sell kits or pre assembled ecus like this. Depends where you live, I got mine from the UK, from DIYEFI. Otherwise you can look up the bill of materials for the ecu you want and order all the components yourself. Check out MegaMicra here on KZbin as he has a series of settings up a V4 speeduino ECU to a 1.4l K11 Micra.

[@SeeLikeMe]

@@the_mintiest_micra thanks man do you also have a scheme for it or something so i can check all of it

[@ouew3872]

Doesnt the micra already have a ingition module somewhere?

[@the_mintiest_micra]

I'm not 100% sure, I think the distributor engines have an igniter, but I don't know about the coilpack models, might be built into the ecu hance the need for an external igniter when going standalone with the Speeduino. I do know however that it was necessary.

[@ouew3872]

@@the_mintiest_micra do you know the signal voltage to the three pin coils? I have some beefy transistors laying around and was thinking if i can make my own igiter.

[@the_mintiest_micra]

@ouew3872 I'm no expert so I'm not too sure, but if you're asking about what voltage signal is going to the igniter from the ecu it's 12v. Im not sure what that gets amplified into by the time it actually gets to the coilpack for there to be a spark.

[@robinlehtinen7819]

can you share the map files for the micra?

[@the_mintiest_micra]

Ye mate, latest version of my tune should be in this shared folder. Will more than likely need adjustments, nowhere near perfect yet, and it might work differently on other cars with less/more/other mods. drive.google.com/drive/folders/1e8W5z4EhZHwW03Oq3Q42SkolCVaGhJ8m

[@potopoto6308]

How do you know how to connect the ignition audi module to each cable?

[@the_mintiest_micra]

There's a 5 pin side and a 4 pin side. The inputs go on the 5 pin side in order of the engine firing order (pin 1 is cylinder 1, 2 is cylinder 3, pin 3 goes to ground, pin 4 is cylinder 4 and pin 5 is cylinder 2 for me). The pins on the 4 pin side go to the signla wires of the coil packs (same as input side but no ground pin). Also part number for the igniter I used is 4D0905351, can be found in late 90s early 00s VWAG four cylinder petrol cars. Be very careful wiring the ignition and research the firing order of the engine and in what order your ecu sends out the ignition signals. Good luck.👍

[@potopoto6308]

Thank you! Im puting de speeduino on a Alfa Romeo 145 1.6 Twin Spark It has two pins coil, this WAG igniter Will fit?

[@the_mintiest_micra]

That's cool, will you be using all 8 spark plugs? I think all two pin coils need an igniter to work with a Speeduino, usually 3pin coils don't but the Micra is an exception as they're still "dumb coils". I would assume the igniter will work with your coils but definitely double check, read the Speeduino manual and see if you can find any info and specs on the hardware your engine has.

[@willembroeders473]

Where can i buy the speeduino kit?

[@the_mintiest_micra]

I got mine from DIY EFI in the UK but depends on where you're from, they sell a kit but you can also buy all the materials separately yourself.
