- Some time ago I did design this Arduino Mega replacement board for Speeduino ECU that uses STM32F407 processor. With this processor board you can have all the modern features that Speeduino offers, on your old speeduino ECU just by swapping out the processor card.

The guy not only is a mechanic and electronics extraordinaire, but gives us his hard work and design efforts for free instead of doing business... I sometimes feel like we don't deserve you! hats off, Sipa.
I agree 100% with you!
I admire him.
Good job man!👌🏻
Wow how did you teach yourself how to do all this stuff man ❤
Now I’m thinking to get one of these ecu to convert my 94 m3 on to a more modern ecu. Would you say this Is this the best solution ?
This guy is an amazing member of the Speeduino society. If only he understood my mother tongue.🤣🤣
Well yeah I only speak Finnish and English..
You’re a saint. I was gonna do this but never got to it and you’ve done it way better than I would have lol.
Thanks for your work. Sub
Hello pazi88 . This looks very good. Can I use this in ms40.1 m50tu?
Well, yeah, if you have already speeduino running on one that uses ie. v0.4 pinout.
Amazing work pazi, as always ❤
Thanks!
Hy Pazi! Can you help me? I have M52B28 single vanos, and i need IAT and CLT sensor calibration... where can i find the bias resistance, and the temp-resistance table? Many thanks :)

Is it possible to do a video as to how to enter the good information in PCBway to get the correct copy of your STM32 ?
Hello, thank you for your Video. I can't order a pcb because its to hard for me with a lot of options at Pcbway. I like to have a board like yours with a little bit of soldering. Maybe you have a link where i can order it.
Hi! Unfortunately these aren't for sale anywhere currently. You need to get these made by yourself.
is anyone producing this as a drop-in for purchase? I would love to upgrade my ecu to the 32bit, but I have no time to reproduce this excellent work.
I have the PNP Ecu for the m52/tu from DIY-EFI, can i replace that main board to this STM32 version?
Unfortunately no. It doesn't use the standard Arduino Mega board, but the Core4. So this doesn't fit that.
So Cool, very very thanks for your work. sorry i´m very new in pcbway, if possible, can you explain how to make the order on pcbway?
13:28 Gauge.S foreshadowing :D
Yeah it will be in the next video (finally) 😄
Finally. The arduinos uncontrolled power really headache. While road tuning the engine shut off and on.
Thanks to you the e30 ecu community has evolved to another level, to bad mine is diesel :P
PCBway sould have given you a sonsored link so you get something more out of it.
Yeah bit strange that they didn't give any sponsored link or so. But at least they gave me free hands to do anything with the video, so that's nice 😁
Thank you very much for your work! This is awesome!
Could this new chip allow us to have more inputs and outputs?(soldering new connectors) On old boards? Or we would need a whole new ecu to take advantage of the higher i/o of the stm32 chip?
The number of IO has never really been a problem. Even the Arduino Mega has way more IO than you need. The Speeduino boards just don't utilize those well (and earlier there really weren't features that would have benefitted from that). So not even half of the IO is actually being used. I have designed my newer boards to have more IO than other Speeduino boards have to be able to use the new features easily. Problem in Arduino Mega has been lack of timers to do more than 4-cyl full sequential, but this board solves that problem. And also the Mega doesn't have enough external interrupt enabled pins to be able to use all features that require those. Like VSS, dual CL VVT, flexfuel etc. But this board solves that too.
@@pazi88 Parabens e Sucesso Sempre!!!
Thank you for your amazing work, keep it up! Also i have a question, will we be able to setup basic traction control (i.e. rear wheels speed > front wheels speed or external signal to lower engine power)? I have an a idea to use BMW's DSC mk60 (it's kinda standalone for ABS) on my E30 and it would be great to read signal from DSC to ECU that it should reduce engine power to gain traction, it's might be hard to implement on cable-driven throttle body, but i should get away with spark and injection cut.
Thank you Pazi for helping the community so much!
I also appreciate your English a lot - best regards from Germany
Hi. I’m interested in using this with an NO2C board to improve stability with a dash screen (mega has slow refresh & crashes). But I use modified firmware to get 4 channel injection (sequential). Is it possible to upload custom firmware or do you modify the speeduino firmware to work with your custom board?
Yes, should work fine.
very interesting, I'm currently soldering ms 41 rev2.0, after that I'll try to order this board on psb. After installing it, do the jumpers need to be disconnected for bath fire and wasted spark?
The jumpers between wasted spark/sequential and for injection too were on the rev2.0 because of the speeduino FW limitations at the time. With current FW versions, you can leave those open and assemble the board with 6-cyl sequential fuel and spark. Then run the custom 6-cyl sequential injection FW in the Mega and use wasted COP mode for coils and it will work. And if you later upgrade to this processor, you can just switch to sequential ignition in TS.
@@pazi88 great, thanks for the tip
Hello, great project. I assembled a board, uploaded the latest firmware, works ok. Howerver when i try to set the time in the RTC i get an error "Timeout of 1500ms. expected. time:1583" Using the USB mode not the FTDI.
Yes. Just set it again after the error and it's fine.
@@pazi88 I did it but it doesnt seem to get the correct time. Still shows the old time. Battery is also in.
This is amazing, thank you for being awesome and bringing this to the public.
Great stuff man! I have GOT to get Speeduino up and running on my E30!
Can someone please help me with components for ecu, some of components i can't order from digikey they are discontinued and i dont have alternative components i mean idk what to use as alternatives.
Can you be more specific that what components are discontinued?
Magnificent work - simply stunning
Thanks.
You are such a legend. Massive respect to you.
Where can I find this board for sale?
As I said in a video, you need to order those by yourself.
Hi bro my speeduino not firing up no fuel injected no spark
Ask from Speeduino Discord: discord.com/invite/YWCEexaNDe
I am using STM32_mega for a motorcycle ECU with a Ducati engine. I am not using it on a real car yet, but it is working fine on an engine emulator. There is a discussion about "SD logging" on the Speeduino forum "STM32 development".
I have a few questions.
1. What exactly does it mean that SD logging is experimental?
Does it mean that SPI mode is used for data transfer?
2. Why is the SD logging menu disabled?
3. How can I get SD logging?
Any information would be appreciated.
It was experimental at first, because it was working for me only and no knowledge thst does it work for others. But AFAIK, it works fine currently. Change the MCU to STM32 in the project config in TunerStudio and it should be enabled then.
@@pazi88 Thank you for your reply.
I understand that it should work.
I think there may be a problem with my hardware or software.
Thank you for this project.
I completely forgot that there was a board type in the engine settings. After setting it up, I confirmed that the SD card worked properly.
Thank you.
Can this board run rus efi firmware?
@@livewire2404 I know some have done it.
This is really helpful
This is so useful. Was looking at vems but this gives us an open source solution that can be upgraded and extended. My S52 is going to be very happy using air density and and turbo.
@pazi88
Thank you so much. Most of the Mega based boards meet my needs except for motorcycle I4 engines that go 16,000 RPM.
Order from PCBWay in progress.
can you tell me how to get the sequential ignition and injection to work? I have used the binary files from your github and changed in tuner studio to sequential but doesn't seem to change anything on the outputs.
You need cam signal.
@@pazi88 after restarting the board the hardware test output is working. I can turn the ignition leds individually
@@b3dr01994 Ok. It should prompt to reboot the ecu after changing things like that. It needs to reset properly to apply those kind of changes.
very good very nice 😋🫰🏽
Mitä oot opiskellut ja mitä töitä teet? Vaikuttaa hyvältä toi kortti!
Tietotekniikan insinöörin oon AMK:sta, ja tällä hetkellä oon Keysightilla töissä. Voit googlata firman, jos ei oo tuttu 😁
can STM32F407 processor utilize knock control ?
Thank you, Great job! I'll try to use it sometimes ;)
Great job pazi and great contribution to the speeduino community
Amazing! When will you upload it?
??
@@pazi88 on GitHub I mean, but I already found it. thanks for your work! 💪
This is cool, thanks for your open-source contributions. Technically speaking I could also make it work with your older BMW PnP boards? I have one of yours for M42, it works flawlessly, but it would be cool to also have CAN bus in E30 (with Gauge S) :)
It should work just fine on any speeduino v0.4 based board.
Aivan loistavaa! 🙏😮Kiitos Pazi! ❤
Thanks for the work, I finally managed to get stm working! Do you have any tips or 4-cylinder projects to help me?
The BMW in the video is very beautiful!
Hi! Thanks. No I don't have any specific tips for those.
Wow, English!! Very nice very good!!❤
You are a saint. Could i just buy a few from you lol
If i change the cpu can i use the same tune?
I have the 2.0 board m50nv with sequential injection would this change enable sequencial ignition also?
Thanks for the videos i have started my e34 build learning from your channel
Yeah same tune should work just fine.
Great job ;) When will be avaible 202310 speeduino firmware for this??
Thanks. The 202310 is full of comms bugs, so I wont be making it available for these. I'll wait for next one. There isn't really any new features on that, so it doesn't matter.
Great work. Seems like fun. Just ordered five PCBs from PCBway. Where is XTSD04GLGEAG / U13 supposed to go? Found it in your all components BOM while trying to figure out which components I have to order myself.
That's alternartive for the sd-card slot. It's basically sd-card in a chip. But if you have sd-card slot there, you can't even install it.
@@pazi88Suspected as much but had to ask. Thank you for your prompt reply. Looking forward to trying things out.
I övrigt anser jag att Danmark gör bättre lakrits än Finland. Salta pingviner ❤
Would you mind to explain to me why it allows the original speeduino to run up to 4 extra cylinders? I'm new in this learning field and I'd like to know more about mods for these chip Ecu's
In speeduino the Arduino Mega only has 9-timer channels left for inj/ign outputs. So it can run up to 4-cyl as fully sequential. But with this, there is plenty of timer channels to run 8-cyl as fully sequential. Or even 12-cyl with some code changes.
@@pazi88 thx for the explanation! :) also, with this one it wouldn't be necessary to buy the Arduino one right? I could straight up buy this one
Speeduino saint!
😎👌Great Work!
Nice work 👍👍👍
great stuff
Any way to order your PnP Speeduino units fully (or mostly) stuffed? Do you have pick and place files for those or is there any way to get those?
Most of my designs are with through hole parts, so I don't think it's feasible to get those assembled. But the rev 3.0 M52 board is SMD and so is the m52tu/m54 one. And for those the pick and place files should be in GitHub.
thank you@@pazi88
@@pazi88 any plans to update the m50 board to 3.0?
@@tre_2EC0 Yes it's in the plans, but I don't know when I have time to do that 😅
Is it possible to convert ms41 to ms41.2 or something?
Yes it is.
@@pazi88 would you be that kind and make a video about it? Btw best youtube channel!!
Miksi pakettia ei voinut avata Fiskarsin kirveellä 😂
Oli tarkotus, vaan vaimo oli pätkiny sillä VOM koiranruokia ja haisi niin pahalle se ettei kehdannu käyttää 😅
Oon odotellut koska näitä tee se itse ecuja tulisi suorasuihkutukselle. Kaupalliset vielä yllättävän hintavia.
Tuskin ihan hetkeen on tulossa. Ainakin mitä oon DIY yhteisössä tekemisissä, niin ei oikeen hirveästi ole suorasuihkutukseen kiinnostusta. Lähinnä kun niissä kummiskin melko äkkiä tulee rajat vastaan lisätehoa hakiessa (mikä on se juttu miksi siirrytään pois orggis ecusta). Niin sillon on vaan helpompi siirtyä perinteisiin suuttimiin.
@@pazi88 karstahan on kaiketi suorasuihkun ongelma ollut ja siihen on reagoitu laittamalla toiset suuttimet perinteiseen tyyliin. Eli isot perinteiset rinnalle niin tehojakin tulisi ja muutoin käyttöauton normiajelut menisi sitten niin että lisäsuuttimet olisivat suurimman osan ajasta kiinni tai lähes kiinni. Se Linkin ecu ei nyt enään maksa kuin 3keur mutta sekin on liikaa kun koko koneen saa monesti jo siihen rahaan. Toivottavasti sen Linkin joku hakkeroi😃 ja muuttaa esim. Speeduinoon.
how much does it cost to make?
Roughly 50€ per board with current prices.
Uskomattoman hienoa työtä taas kerran. Ihan oppimismielessä haluaisin kysyä kolme kysymystä. 1. Onko usb-c:n käyttämättömyydelle jokin perustelu? 2. Miksi et käytä Linuxia näissä hommissa? 3. Joko kennotit Thinkpadin akun itse? YT:ssä on video jopa pcb:n reverse engineeraukseen ja videon sponssilla valmiit reseptit :D
Kiitoksia! 1. Oman kokemuksen mukaan tommonen THT USB-B liitin on kaikkein jämäkin fyysiseltä rakenteeltaan, mikä on iso plussa autokäytössä. Niin siksi valitsin sen. Toki ko. projekti on saatavilla EasyEda:ssa että jos haluaa, siihen voi vaihtaa USB-C liittimen
2. En oo ikinää oikeen lämmenny Linuxille, vaikka sitä oon koittanu opetella. Onnistuu kaikki hommat niin paljon nopeammin winukalla.
3. En oo vielää, mut pitäs kennottaa 😅 Monia akkuja on kyl tullu kasattua ja korjattua, mut noita thinkpadin akkuja en oo väsänny.
@@pazi88 Kiitos vastauksesta. Oman T430:n akkukesto tuplaantui uuteen tarvikeakkuun verrattuna, kun nakkasin Panasonicin kennot sisään. Pitää vaan muistaa herättää jumpperilla se turvapiiri 0V:n jälkeen ennen kuorien kiinnitystä.
@@vicmac3513 Joo tuossa on aika kuollu akku jo, vaikka onkin isoin tehoakku mitä noihin on saanu. Varmasti riittäs akku melko pitkään jos tuon kennottaa uusiksi moderneilla kennoilla.
Nice job man! Congrats!
Thanks!
Hi pazi. a very good evolution to this speeduino. I have a question, do you plan to develop a kind of speeduino for 8HPxx box later?
Not really. 8HP is really complicated beast and good tcu controller for it is hard to acheive. I know there are few tcu's for it that replaces the stock one, but those aren't really good for street car 😅 But anyways I plan to step up to the 8HP game with in my mind better option.
@@pazi88 yes indeed there are not many ecu for the gearbox the only one that I know is turbolamik I also currently mount an 8hp but I am missing the calculator.

Meinaatko enää tehä videoita suomeks? 😁
Joo, kunhan UA-cam enabloi mulle ääniraidat eri kielille. Toki tuleva bimmerparty video on suomeksi, kun se ois vähän hassu puoleksi englanniksi 😅

Hello sir,
can this board be used with: Ramps 1.4 Controller ?
is it faster in processing printer data?
kind regards
I would guess that no. There is a high chance that this has different pins in use than that.
