Default Speeduino an alternate to Megasquirt.

Anyone heard of Speeduino or have any experience with using it as an ENGINE MANAGEMENT SYSTEM?

http://speeduino.com/wiki/index.php/Speeduino

It will be 160 if you buy one all put together without the Arduino which is another 25$

OR

If you put it together its like 75$ each. The speeduino site says 8 dollars but the back-order on it is a week out. I was hoping to find a place I could print them more locally.

The site digikey had good pricing on what I wanted to order and they offer free shipping over 100. I put together all the components for 64.51. I didn't want to order the ~19 dollar case though. http://www.digikey.com/short/3rw0w3

On the canadian site the same components are 91.49. http://www.digikey.ca/short/3rw0vq

Last I checked the dollar wasn't at 70 cents.

Im going to order double the amount of components for 116.08, this way I get the US American discount, No unfair exchange rate, and twice as many parts plus FREE SHIPPING!!!

http://www.digikey.com/short/3rwv72

I was also going to order 2 of these http://www.sainsmart.com/arduino/contro ... cable.html for $27.98.

So for 72.03 I have the arduino and the components minus a board.


I am just starting to now feel like I should be getting into this and changing the fuel maps and injectors etc and finding out the results. I am wondering if anyone here has used it, it tunes with TunerStudio.

There is a lecture of the guy who developed it.

That's interesting. Building an ECU using the Arduino platform wouldn't be my first choice.

Arduino is generally setup for ease of newbie development, and not execution speed. I'd guess that with a big processor (multiple hardware timers and input/output capture units), non-standard high-speed I/O libraries, some custom interrupt handlers, and a good fixed point math package, that you could get an ECU working. I'm not sure how easy it is to add hand-optimized code to Arduino, or what's available for good push-button compiler optimization.

I guess my main questions would be: how many engines are successfully running it? how active is the development - if the one main guy gets bored, will the project survive? what quality of support is easily available?

Although it's dated and no longer has any active development, a basic MegaSquirt 1 CPU and basic PCB 2.2 build-it-yourself kit is ~$170 (aluminum case included). On the other hand, MS is not open source and development has pretty much stopped on the more affordable versions (MS2 & MicroSquirt).

I'm hoping FreeEMSFred will chime in here too since he's active in a more mature MegaSquirt alternative.

Is Free EMS the Russians? Haven't heard from them in a while...

EDit - Nope not the russian = rusEfi

Free EMS seems to be active, but stalled awaiting development of more permanent hardware layout?
No new boards have been made in 1.5 years. (jaguar 0.7?) (waiting on hardware changes?)
Difficult to tell what is going on, the forum seems like a diary/scratch pad for Fred.

MS1 is vintage

MS2 is still under development some MS3 features are even being folded into the MS2 code,
MSExtra 3.4.3 is in the pipe.

FreeEMS has 40 documented installs, the latest was posted Sept 16.

I'd buy one and give it a twirl but with the last board release 1.5 years ago, I'm in wait and see mode.

I'm actually looking forward to trying one as that will force me to learn a new skillset compiling code.

MS1 as perhaps no more developpement but it most case can do more than necessary for a fair cheap price

Development for MS2 has halted, they are now refusing to backport even simple features from the MS3. That being said, I would be skeptical of any engine management based on an arduino. It's a development board and not meant for this type of application. There really is a lot to an engine management, an MS2 or MS3 would be a much better investment.

microsquirt is a boring proprietary product which loves sending "cease and desist" letters - but well, it's their property their license so it's their rights

rusEfi has 29 installs I think, couple of lemons races.

I would say nothing is wrong with lack of new boards per se - rusEfi (with which I am involved) is also enjoying the same Frankenso 0.4 board for close to two years now. We are kind of getting closer to Frankenso 0.5 but 0.4 is simply good enough. http://rusefi.com/wiki/index.php?tit...rankenso_board

It's great that http://speeduino.com offers assembled boards! that's the way to go. I know that 90% of rusEfi kits are never assembled - success rate for assembled boards to drive is much higher. No assembled rusEfi boards in stock right now, hope to get these back in about a month.

I do not have a good answer. Probably not much. It's definitely the most proven entry-level system.

I need to add some game changing feature into rusEfi - currently looking into either on-board WBO controller or electronic throttle or build-in fuel auto tune.

Does microsquirt have build-in knock detection?

MicroSquirt is a cheap entry level substitute for a MS2 v3.0

I'd give rusEFI a try, but I wasn't sure about ordering off a site that I knew nothing about. The internet gives a lot of old/dead sites an extended life span ;).

I'm going to peek at it again. I found it last year and have been checking in every so often.

These projects seem to loose momentum after they get a few running and realise the flaws require a complete rewrite and or more expensive hardware to fix said flaws.

This. Bang for the buck with microsquirt is hard to beat.

Well, somebody has just joined the rusEfi forum today and just posted a video of a first volvo running rusEfi. That's engine #30 by the way. I am checking with the guy if he has a thread here, if not I will start a separate thread for rusEfi.
