Thank you for modernizing aging ECU's into opensource soft and hardware!

I cant wait buddy. these are going to be great ecu's. We are going to make alot of people very happy in my area.

"There it is. A 600 MHz ECU." Absolutely wild.

In the late 80s GM introduced the GMP4 ECM. It boasted a 2MHz 68HC11-based MCU running out of a 27256 EPROM (something like half of which was calibration data, the rest program)and had 256 bytes of RAM, some of it battery-backed (for learned parameters and diagnostics.) The ECM, along with the previous generation C3 (even slower) basically ran GM cars & trucks from the Cavalier to the Corvette until the OBD-II era. It controlled fuel injection, spark timing, EGR, closed loop idle speed and had a pretty sophisticated suite of sensor diagnostics (GM's "ODB-I" including an 8192bps serial stream.) It used 2- and 3D tables with interpolations, pioneered short and long-term fuel trim strategies etc. I had a great time reverse engineering the P4 out of my Z24 back in the early 90s. I'm glad Josh mentioned the fact that 600MHz wouldn't really get you a lot in the big picture. The memory & speed of an ATMega2560 dwarfs that of the P4's MCU and it would (and does) obviously make a great core around which a full-featured ECU could be based. What would you do with all those cycles when controlling a Victorian-esque reciprocating machine that could be controlled by a 2MHz MCU?

inb4 'Making a 5GHz liquid cooled/phase changed cooled ECU' :D I've also just discovered Speediuno. Pretty much combines my love for mechanics/electronics/programming all in one and I immediately decided that I absolutely had to throw one together. Just waiting on parts and then some free time. I LOVE that this is a thing now! Great work!

Just started looking into speeduino and my first thought was about using a teensy instead of an atmega. Funny you should happen to have a video on this.

Awesome work

Just subscribed to you after finding your channel in an quite unusual way. I was browsing a Chinese Import website and saw a new empty ECU Case. That made me wonder if I would be able to build a ECU from a Micro controller. Just 2 clicks later I found what appears to be a clone of an early prototype from your project for sale on said Chinese import website 😁 That made me google the name of the product and that's how I found your channel.

Thank you sir for creating speeduino brother, I have 2 speeduino based ecus, I really love the updates and bug fixes that keep making the Ecu more up to date as things progress. keep up the excellent work brother.

Thanks for your contribution.

Holy shit the loop speed 🤣 amazing work.

There are no words. Except what an absolute legend this bloke is 👏🏼👏🏼👏🏼

Super video! I applauded for $2.00 👏

i hope any board printed in 3 layer and made it only 1 1/2 credit card size.. and I really interested to try this ecu in my motorcycle, just 130 cc but convert from carburator to fuel injection

I wonder if something like this could actually do something like traction control and some of the stuff like ABS and the Yonder.? well I think this board allows is that you can use a hybrid setup and that's probably where this board is really going to shine. this includes something like stability control and active role control things like that can really bring out the best in a vehicle especially in a heavy car.

It'd be interesting to see an MCU chip based on a SiFive X280 or similar core (maybe some ARM thing with SVE). 512-bit vector processing in a chip with good RT, timers, and IO would make some mighty interesting things explorable (finer nonlinear predictions? ML training and inferencing? microphones in the intake manifold?). I read a paper the other day on using neural networks in combination with a conventional physical model and conventional sensors to explore and optimize control signals, they evaluated it for predicting exhaust temperature (which was apparently useful for an EGR system), it seems like it could be something to look at. non-linear model predictive control in general is something to look at.

Are there any speeduino configurations that can run 4 OCV valves, 4 cam position sensors? Subaru dual AVCS here so still for 4 spark plugs and coils. Been looking at the website and only see support for 1?? camshaft sensor and 2 OCVS Thank you for the work this is amazing for car enthusiasts

Evening Josh. Looking at installing (hopefully) a 400+ cubic inch gen3 Hemi into a Plymouth Duster soon. Will this future ecm change also have the ability to fire all 16 spark spark plugs at the same time, do an exhaust stroke wasted spark or only fire single sided coils ? I was looking at the MSD wiring harnesses to adapt to the engine , just looking for a decent controller. I just came across you guys while watching some how to videos on a couple tuning programs. Thank you for the information on the site. Looks like an amazing piece.

Am I right in assuming that the Arduino mega can be configured for 1 channel of spark and 8 channels of fuel? Or was the 9th (if I remember right there 9 timers, and apparently that's what matters for that) timer used for something else? I'm thinking locked distributor and fully sequential fuel.

Great job my respect 🫡

Hi. Is there knock sensor input? It need a madule? Is there a cheap way to have the knock sensor module?

I have a V6 with coil on plug engine. Trying to figure out how to make a speeduino work on it. Really I can double up injectors but can I use 2 injector outputs for fuel and remap 2 injector outputs to control spark instead? Or does the teenie give you more outputs so I can run sequencial fuel and spark on 6 injectors and coils? I've always been a diy guy! Heavy into electronics and build fpv freestyle drones that have stm f405 f722 h722 processors and learned how to re map pins to do a different function. Is it possible to do with speeduino or is there a board and parts you reccomend? It's a 06 honda pilot 3.5 j35z1 engine and automatic trans. The reason I want to do this is the engine is strong even with 300k on it! Want to run forced induction on it and remapping the ecu has been quite a daunting task! Hondata doesn't support my year ecu and just bought a scanner tool that's bidirectional and claims to do ecu programming and coding! Knew speeduino existed but always drove gm vehicles or vehicles with tons of aftermarket support! I have a ton of arduinos and esp32 chips kicking around for thinks like wifi deauthing my sister or controlling leds. Discovered a can hat for arduino and building a can reader to maybe try and do a ecu dump and poke around in the code! My old bt dongle was able to rip my ecu wirelessly and create a dump file and could use pcm hammer to edit the code but no way to reflash the ecu! Also do you know of a good resource for what vehicle use what protocol? Thanks you in advance! And thank you for doing all this work! I know how much goes into making custom hardware and then write firmware and software for it to do what you want! So thank you and if I had a better attention span than I do now I would be doing the same thing!

This is interesting but can you tell me if i could use this ecu as a piggy back or as the ecu it self to run itbs on a N/A 2014 mitsubishi lancer ? If i can can you tell me where can i get this fully assembled or if i have to assemble it and if you have a parts list for this where can i get it thanks for the videos this opens a los of Doors for tuning

Seeing the unavailability of the Teensy 3.5 in the near (or even far) future, any plans on boosting support for the 4.x series? I'm aware that the processing power isn't necessary, but for managing more than 4 cylinders in full sequential, the Arduino Mega ain't enough!

Thank you so much!!!!

probably could run one on a rp2040 [dualcore arm mcu from RPF] as well, probably might need some external ADCs though

i wish there was an option for my old bosch edc landrover ecu and the stupid needle lift injector issues gogin to be easier to put a BMW n57 swap in it

Do you have any model of plate that makes ignition and injection sequence 5cil fiat?

Hello, I have a Speeduino powered Scg-ecu 1.0 board. When I install the Speeduino v202103 version, there is 2.4 volts continuously on pin 31. This pin is the ignition pin. When I install the Speeduino v20208 version, 2.4 volts is not always available, but when I test it in Tunerstudio program, it comes to 2.4 volts on pin 31. 3.2 volts comes standard on other ignition pins.

Ever plan on making more of the drop bear?

Next: ryzen 9 18 core 5 GHz liquid-cooled ECU (may need to upgrade your alternator to power this badass)

You have an estimate of when the speeduino dropbear will be available, I am very interested since I have a v8 engine that I want to run in full sequential? Thanks you for your grate work.

Hello and thank you man! I don't know if Ur going to answer to my question! What's the newest bord for Teenesy 4.1 adapter?

You still have that old mazda, R&D car :) Any way excellent work Sir and thank you for upadate . I can't wait for dropbear to show up. Greetings from Bosnia and Herzegovina

could you guys make one for the ae86? or at least one with pinout diagrams so i can make my own harness. Id love to get one just to do a simple supercharger setup with one

Im assembling a speeduino board, and I think that others share my happiness to see new videos on week basis. A tip, open the channel to permit paid members.

I wonder how a Parallax Propeller/Propeller 2 would work for this

Hi mate, can speeduinos work for na8s? Everything I'm seeing seems to be on a 1.6. Thanks

Hi, why speeduino dont have updates for remplace the 2560??

Just to think, they used to do the same thing with tiny toilet valves and adjustment screws.

@Speeduino Will there be any more updates/upgrades for the old 0.4.3 models, Josh?

would have been nice for you to list why you want to stay with 3.6. you just said there is a couple reasons and left it.

Are there any downsides to using that board and what are the advantages just faster response times and stuff or what

Hey man, love your work, keep it up! quick question, i have an arduino due and have some trouble uploading the firmware to it using the speedyloader, it keeps giving me that avrdude: stk500v2 time out message, could it be that the speedyloader only works for the mega 2560 or am i missing something? since I've seen yoyr previous videos using the due instead of the mega, I'm new to the arduino and coding world so definitely looking forward to your reply, thanks in advance! (Sorry for my bad english)

Is it possible with this fast cpu to change the int values from the ve table?

With the 3.5 board being delayed until April 2023 and the 4.1 shipping shortly what are the chances of being able to get a dropbear bare or with a 4.1. I am waiting to build my first fuel injected motor and was hoping to use a dropbear but I understand the supply chain issue throwing a wrench in things.

SO IS IT MADE FOR MY OBD1 HONDA IF SO WHERE CAN I BUY ONE

is there any plans to make a 6 cylinder universal ecu? if not which do you recommended to someone whose on a budget?

This is the first time I heard of Speeduino. I played with Arduino a few years ago for an auto application. If I have time I would love to give this a try for one of my track cars.

Would this work with an automatic gearbox? Planning on using this with a dq500. Originally planned to use an MS but then discovered this amazing ECU

Interesting, how it will compare to Portenta H7... That thing got ARM M7 core running at 480 MHz coupled with M4 core running at 240 MHz, which could be great for parallel stuff like oh, I don't know, computing on one core and logging/transmitting info to dash on another?

Tanks friend god bless 😅

Would this do 16,000rpm for a cbr600 motor?

Yo very far off topic but slightly related. Any thoughts on a Framework mainboard being usable as both an ECU and in car media center?

Can these boards run i-vtec ?? K20 engines

I have a question on how to wire up a idle PWM two wire controller (ford mustang idle pwm) on speeduino .4 board. you have pin #37 and what other pin from speeduino board do you connect to? ecu ground? thanks for your help.

im running an on/off switch to my supercharger, will the speeduino be able to correct itself on the fly or will i have to change the tune manually ?

Thank you this is the coolest open-source thing I have seen

this is so stupidly awesome :D

have you used simulink at all to help you with the ecu??

Is the 3.5 capable of running v12 full sequential if we really wanted to or you would choose 4.0 for that??

600 Mhz at them! Love the growth I see of Speeduino over the years!

With greater speed and larger storage, will per-cylinder, as well as adaptive, fuel mapping become available?

Do you make a PnP foe the 99-00 NB Miata?

would this fit in my link ecu?

🤔 Hows abouts a TCU (Transmission Control Unit)

@speeduino hey i have a project coming up which includes dual engines and i would like to control both engines simultaneously on one ECU i would also like to have D.B.W. on both as well as a strain gauge to shift both transmissions sequentially is this something a 8 cylinder capable ECU could handle ?

What are the advantages of the 3.5? I'd have thought standardise on the latest, balancing cost & speed.

Why don't you increase the size of the injection table and ignition table, since now there's more power available?

Just found out about your product and look forward to learning more!

So is this available yet?

It's been 3 years. Ik hope this is going to be released.

When do you think the dropbear will be available?

What is the cost???

i dont know much about ecu but im assuming faster processing,more accurate data?

Any plan to release the board as an open source ?

that is orders of magnitude... DAMN...

Is this thing for sale?

Do you think the 4.1 will enable use of SENT sensors or do you think the other processors are capable?

Can I use speeduino for a honda k24? Vtec and vtc?

I'm in love with this ecu and I don't even own one YET, once they're back in stock i will be purchasing one. I'm also laughing because of the thousands of songs available in the youtube library i used the exact same songs in one of my recent videos.

Isn't the Arduino Portenta H7 a viable option?

Waiting for RGB on the board ;)

how does the speed compare to a Raspberry Pi 4?

I don’t see those boards you were using for diy or purchase

cant wait to get Teensy 80.1 and 5ghz

can we have 100hz logs now?

Does the 600 mhz mean 20000 rpm rev limit

The added processing power is only useless until some nutter finds a use for it :)

This fast enough to use on a rotary application?

👍.

I think this has been a long time coming: faster processors allow for greater sampling rates on analog signals/sensors, so by theoretical extension you can get more finely tuned in terms of overall vehicle performance. This should be the way forward as far as I’m concerned

hmm.. i think it would be cool to have a free ecu memory gauge on the dash

put a link to speeduino in the description of your vids

Hello, I am an engineeringstudent in France, studying electronics/programming. I am about to start a very interesting school project and I need your guidance! I own a Honda CRF250L 2018 engine (single cyl 4 stroke) and a go kart chassis, the plan is design all the rest ourselves: ECU/Harness design, touchscreen dashboard, flappy paddle gear box and servo for the clutch (previous project but swapping from an arduino for a custom circuit), full lights (including brake lights/indicators) and possibly a pivoting rear wing. The project is replacing work experience so it is supposed to last 12 weeks (35hr/week). Do you have an email to contact you directly? Thanks in advance!

Am I crazy to assume you can use a faster chip to run closer to lean making more power in a safer manner?

No matter how fast it is still backdated. If there is DBW function I would say yes it does make some forward moves but just adding more drivers I think it is pretty useless.

threadripper ecu when

Are you going to make it now up to 12 cylinders ?

well..... my first ibm pc was 4.77 MHz/16 bit, so ...
