I thought that GD was a full-cycle manufacturer. Do they source wafers from some other companies? People say, this crisis will last for at least a year. Changing a package in the PCB probably takes a few hours. If you are switching to a different package within the same MCU, probably there won't be ...

considering this ongoing crisis, why not GD32?
GD32F190 is a 5-V series.

A new alternative?

тут не нашел нигде, нагрузка как считается? и каким образом дроссель выполнен? такая диковатая идея возникла: на мелких (одно-двухцилиндровых) моторах имхо можно попробовать переписать процедуру запуска, подключив к работе еще и датчик давления (если таковой имеется в сетапе): при появлении вакуума ...

хм, любопытно, а давно такое требование появилось в вики по русефи? насколько я помню, изначально предполагалось любое расположение, с возможностью корректировки исходного угла в настройках. про актуальность для кик стартера - имхо зависит от того, сколько оборотов удается получить в среднем при исп...

220V? how safe is it? I've read that you shouldn't use soldering irons connected to mains for soldering electronics since you can ruin ICs..

Will it be just one WBO (considering initial notion of 8 cylinders, which probably implies two banks of cylinders, hence, two WBO sensors)?

which model is that COP? what's the benefit of ion sense-based misfire detection on wasted spark modules? i reckon, misfire detection feature is especially handy for V8 engines since it allows you to identify exactly the head which needs your attention, hence, eliminating the need to remove both hea...

Some factory ecus disable injection in those cylinders, which also makes sense.

Спасибо за выкладки, полезная инфа. Надо будет посмотреть на входные цепи mre и сопоставить с даташитом - должно ли оно работать с ptp в сотню мв...

NOTE: "fully sequential" gets touted as some holy glorious ideal of EFI, but it's not really required. You'll get better idle emissions and slightly better fuel economy, but at high load/rpm, you're not going to notice a difference. The only potential real difference is that since you kno...

"сигнал очень слабый" - что за измериловка использовалась?
имхо смотреть на расстояние между зубьями диска и сердечником, плюс не знаю как тут, у меня сечение сердечника имело прямоугольную форму - от поворота этого прямоугольника как будто менялся результат.

Где-то попадался аппноут про то, какой размер должен быть у зуба относительно сердечника датчика. Я бы смотрел сигнал осциллографом, прежде, чем делать выводы. Ну и попробовал бы повернуть датчик по оси.

what a large topic with plenty recent updates

This will make the local copy of the whole bunch of not needed stuff - hardware files, etc. That's a pity there is still no known way to copy just the source files required for firmware build.

What if using ts just for configuring, while analyzing tracks in logic analyzer? Saleae now have several analog channels, plus here are (if i am not mistaken) opn source variants (sigrek?) - but this would require saving logs in those formats..

This could be a handy tool to make timestamps of interest in the logfiles... This would probably make the further analysis of logs a bit easier.

Just a thought: with all these wireless connectivity options, security becomes sort of a concern. I'd suggest to implement a 'read-only' mode for such communications, to be enabled/disabled either with a physical jumper or a password-protected checkbox.

Let me know when (if) you start selling it - I would be happy to by one of these. :D The advantage of esp32 is that it can be used not only via bluetooth, but also as a wifi (dunno, either a client, or an access point) The drawbacks are: these boards are probably trickier to set up, plus BT is BLE-m...

funny thing: I was about to place an order for a breakout board for an automotive ECU connector to be wired to my old frankenstein (finally realized that those small round-shape connectors I had first chosen were just pain in the ass), and the very same day there was a post by andreika with his modu...

what are the benefits of onboard MAP sensor?
the enclosure is made of aluminium - will it work with bluetooth?

Nice! Couple of dozen components are on the other side of the board - probably need to be soldered manually, but that's okay. If there are some extra pins abailable in the connector - I would add an onboard pull-up to 12V resistor for the vehicle speed sensor + corresponding pins. What's the purpose...

but wait! shouldn't there be a reliefe valve in the cap of the expansion tank?

That's an awesome trick! Haven't heard of using such sensors in mass production vehicles. I'd like to see the implementation of such a solution - I mean, the sensor part number, its proper location, etc.

what's the usual way of checking engine temperature? from the coolant temperature sensor? what if there's a crack in the rad, and all the coolant has run away? will the sensor still provide valid values? i mean to say, for the peace of mind coolant level sensor is a must.

you mean to say pb5 and pb6 of stm32f405rg56 are not 5v tolerant? according to the datasheet, they are! or they are only 5v tolerant as general GPIO, but not for CAN purpose? is it a 2 layer or a 4-layer board? you can still use it: replace the can transceiver with 3.3v-powered one, cut the 5V suppl...

I'd suggest that instead of investing in a 3D printer, you invest in a milling machine
What was rationale behind the 3d-printed case vs aluminum one?

Does it allow to filter out parts that are out of stock?

that's yet another rusefi ecu, this time based on proteus board! nice! was it a batch?

lucky you are that it was not rigol
RIP, yet another MRE
though not sure that your reasonoing is valid...
