Default rusEfi: open source DIY ECU

rusEfi is one of the open source engine control units, we have declared it "release 1.0" about a month ago after one of the early adopters got home from a 1000+ mile road trip. Earlier in 2016 this ECU has finished two Lemons races. So it kind of works

All the required basics are there- speed density fuel, table-based sequential ignition, SD card logging etc.

What makes this ECU different from other open source platforms is that it uses a relatively modern ARM chip, that allows programming in a readable, relatively high-level manner. For users we are trying to provide ease of use and troubleshooting - there is an ECU simulator where you can play with tuning software without any ECU hardware, where is a UI application which allows to query internal state of the ECU etc etc etc.

Oh, and today http://forums.turbobricks.com/member.php?u=59656 has started first Volvo on this ECU: https://www.youtube.com/watch?v=QJFdp2kSeYM

This is open source firmware and open source hardware - if you want to go hard code you can make your own board, if you want to just solder your own board you can order it from any PCB fab shop, or you can buy a parts kit. Sometimes fully assembled boards are also available - that's just a hobby project after all so no warehouse with a hundred of these waiting.

Do you have the files for the board to be cut?

I have been convinced to go this way rather than speeduino.


So I would want to get a few of the following:

1. Where are the gerbers for the control board?
2. Where is the BOM for the control board?

I want to make it myself!!!

Let me know whats up. I want to get my 240 running too.

We have two boards - older smaller & newer larger. Newer larger is the way to go, it's called Frankenso - http://rusefi.com/wiki/index.php?tit...rankenso_board

as of Jan 2017 we are on version 0.4 of that board. https://svn.code.sf.net/p/rusefi/cod...enso_rev00.40/ is the folder with everything including https://svn.code.sf.net/p/rusefi/cod...rbers_R0.4.zip and https://svn.code.sf.net/p/rusefi/cod.../frankenso.csv

If you only need a couple of boards it probably makes more sense to buy a kit from us. If you want closer to a dozen you are better ordering your PCB from China.

Soldering paste is strongly recommended.

Hi.

Interested in a kit.

Please advise.

Just a heads-up for the all thumbs set who want to make it themselves. The rusefi boards I looked at utilized SMDs. Hence the warning about needing soldering paste. Proper soldering pastes are temperature and shelf life sensitive so with the expedited shipping you may pay a $ premium. A hot air rework station may also be desirable.

I have attached SMDs without the proper paste and without a hot rework station. However, I would not want to be doing a lot of it.

On superficial examination, rusefi looks interesting. If I were not on the tail end of a MSExtra implementation, I might be tempted. However, that is an observation made without having looked at the code.

Those people who post questions like 'does anybody have a base .msq I can use?' should probably steer clear of rusefi.

I have assembled a few of these with a $5 syringe of paste and small tip soldering iron - totally doable. After five boards you would get a hot air station or tiny gas torch.

I have found this fellows solder paste in a syringe to be handy. The needle tends to dry up and plug if you don't use it, so I would also suggest getting some extra needle tips. Also I get surprised at how far this syringe goes. I would bet you can populate a couple Frankenso boards with just one syringe.

Thanks for the BOM and the Gerbers for the frankenso. I looked at it. I wouldnt be able to put it together.

I think someone should go to every forum on the web come up with a list of group buys or start a kickstarter and have some chinese company print and assemble these complex boards for a really low price.

Does that exist? I havent been able to find a RusEfi for less than 400 dollars which is more than the ms....

I may be wrong or didnt look hard enough.

Let me know if there is better assembled frankedenso boards out there
Isn't assembled Frankenso $340? Sure you can remove LCD, joystick, SD card module and knock signal processor and get below $300 but that kind of defeats the purpose of having a useful board.

Which MS unit costs $340?
How much is an MS which supports v8 with sequential fuel and spark?

PS: there was a rusEfi kickstarter back in 2014

I believe that if you strip down the Frankenso board until it matches the features and IO of Speeduino, I believe that the materiel costs are very close to the same price. I have not compared them, but if someone did a comparison, I would be interested in seeing the differences between the rusEFI series of boards and other options out there.

Also, do the other projects have an enclosure, harness connector, and harness pigtail for a similar price? Generally that enclosure and harness connector and harness are the big dollar items.

Also did you see Frankenstein? That was a lower cost / simpler option. Basically you can purchase an already assembled regulator, either linear or switch mode, what ever you prefer. Then that board gives you the IO you need for crank inputs, injector outputs, etc. The IO are all routed to via's and you are expected to solder in wires to make your harness connections. So no harness connector, and no enclosure in the costing there.

https://sourceforge.net/p/rusefi/cod...tein_rev00.11/

We have found the people who solder their own, rarely make it to a functional project. We suggest getting an assembled Frankenso. It saves massive amounts of time. These PCB's are all very complicated and time consuming. Most people are not well setup for such levels of PCB assembly. Keep in mind that when you solder your own, your spending days of soldering and days of keeping track of components, such that you theoretically save perhaps $100. In reality when you add up the shipping costs, and purchase errors, dropped parts, etc, you generally spend more to populate it yourself.

We are still playing with all this

Our latest board is the smallest one so far and it supports electronic throttle body.

I have always wanted to get one of these and play with it but haven't.

And the first run on microRusefi was on my 240!
