Re: Proteus - Waterproof, High-feature ECU!

Finding and following the MFG's torque spec on the screws is probably a good idea. Probably also a good idea to only install those screws once. That would likely minimize the connector plastic from cracking. Once the torque spec is found, I might suggest adding a torque note to the silk, so it's eas...

Re: Proteus - Waterproof, High-feature ECU!

I've not looked at it. mck1117 is usually fairly solid in his design process. A quick look seems good to me. I see things larger than 0805 are flying leads, which I believe to be good thermal design. I probably would have put a fudical closer to the STM32 to help the PCB assemblers. The X,Y toleranc...

Re: Hello from germany

Oh, also perhaps worth a mention. We have made many adapter PCB's which are handy for interfacing with an OEM harness. Basically get an extra ECU with a pig tail of wire from the salvage yard. Then remove the connector from the ECU. Then install that connector into a breakout board. Then wire the br...

A key difference with rusEFI is that rusEFI knows what happens in the middle. With ECU manipulation you are trying to control an unknown.

Say 1/3 the vertical, would that be good? AKA keep the 2 mounting screws, and keep the connector that is there, but also keep the costs low.

Re: Ford 60 pin EEC-IV connector breakout board

Breakout board updated. It's over sized right now, as I'm fairly sure the long term goal is to put MRE or similar into the OEM enclosure. So this breakout includes the mounting holes and is a full sized PCB that would fit inside an OEM enclosure. The traces are much fatter than they were. Is there a...

Re: stm32f429 won't connect

Wasn't the pin out shifted by like 1 pin? I recall that was a common concern. If you try it I would say verify the pin out is actually the same. There may be like 1 pin that is not nice. Or that might have been a different chip, I don't fully recall.

Re: TLE8888 Ground path.

I recall the calculated lift of the GND plane for like a 10A current was around 0.001V. That amount of lift of the GND pin is negligible from the ADC stand point. It would be interesting to measure the lift and check it against the real world. That book seems quite old, it was written long before we...

It would be great if you document the process. Once you get it running, it would be great if you could make a video, or a list of key steps and key commands, with key things along the way. Like Pi4 with Linux distro xyz, then cmd make, make install, etc.

We have the outputs, and if it's hardwired, then we can not change it easily. If it's a problem for some unexpected reason, we can change it in software.

Why the concern about driving it with an extra output?

Re: TLE8888 Ground path.

the Achilles' heel of the FQD12N20LTM is the 200V of breakdown voltage, we don't now if 200V peak at the primary could be sufficient for a good spark, we are using a cb600f engine and original ignition coil.

I think that MAXFem could be used to generate the heat generated profile, then perhaps it could also be used to show how the heat moves around on the PCB. Perhaps CAELinux could do it.
