And of course I forgot about the TVA :oops: . Was actually ordering this case, but this is getting too expensive @ about $100 :cry: .

Don't forget your crimp tool(s) as well don't forget your special tools for opening the enclosure. I recall the smallest enclosures don't need the special tools, but most modICE will need special tools.

right now we have sooooooooo many boards we have to stop designing new

right now we need to move software or documentation or adoption, not HW

I think that there is mainly a need for Plug-and-Play (PnP) adapter boards to match specific engine connectors.

Perhaps if there were a loose standard we could encourage people to put their efforts to creating PCB layouts (Gerber files) converting from their preferred engine connector to a standard low-cost connector And then wiring harnesses from that connector to one of the existing RusEFI ECUs.

The connector wouldn't need to be weatherproof, but it needs to be automotive quality for vibration and temperature. It should be readily available and use an inexpensive crimp tool.

If it's not only about the connector, but about the whole enclosure, I'm afraid there's nothing left for people but building their own boards. It's a bit annoying, but you can live with that.
Besides, imho building boards for many people seems much less complex and much more feasible than adding new software features.

Technomelt is a common potting material for automotive applications. It melts like how glue and very chemical resistant. Toaster oven would melt it just fine. Also it's not a carcinogen. You can also get it were it phase changes at say 150c. Aka it could take many watts to exceed 150c preventing over heating.

I have designed this enclosure, and a chinese mfg might be interested in opening a mold to sell them.

PNP are easiest done with adapter harnesses.
A bunch of wires, with female pins crimped in each end are the way it's usually done.

Put the female pin at the ecu header pin, solder and crimp isolation around.

Do you plan for this to be IP67 or similar? I wonder about the water resistance of the USB. As well if they are surface machining a mold, perhaps adding an o-ring groove could make for a nice water resistance feature.

I like the entire you don't see bolts thing. That makes it look clean.

I think the usb should just be a remote connector. There's no point on having it on the box, this way you can have the case inside or on engine bay, but always have the connector inside near glove box, ashtray, whatever you want. This way it's reliable(no weird connections) and weatherproof. That's how I plan to do on microrusEfi when I install it, since it's ready for it.

Canbus would seem like the desired solution for communications.

Looks like tyco 73 pin connector .
Any thoughts?

Would love to find an enclosure to use the molex mx123 connector and PCB header

Harness side of this connector with wires installed cost how much?

Those connectors are pretty common. GM gen4 (2005+) v8 engines use those connectors, I think.

The other consideration with those connectors is that you have to solder the connector once it's installed in the case - so you can't remove the board or access the top side if it's installed in a case.

The pcb header, the connector and connector cover all are available on Alibaba for a couple dollars each.

One seller shows the connector with all 73 terminals for 5 us dollars.

Or mouser has individual terminals for the connector at 0.19 a piece. With 10,000 currently in stock

https://github.com/rusefi/rusefi_documentation/blob/master/oem_docs/cases/BS616%20New%20Harvard%20Cover.dwg is this a 3D file or not really? Does this file provide enough data to prototype PCB outline?

It's an AutoCAD drawing. PDF of the drawing is attached. Seems fairly detailed.

i already made a board for that case.

I have eagle .brd if needed.

I confirm, it's a 2D drawing, which is fairly good and could be used to make a 3D model.

Eagle file would be great! Maybe eagle can export to some vector format? Can you attach original Eagle and attempt to convert into something portable?
