Re: cheap cylinder pressure sensor option - smart diesel glow plug with pressure sensor

100ns per division? so, the drop duration is even below 100ns? do you know what's inside that sensor? it's design? may be, there is a certain ciruitry there which causes that drop? it's a cylinder sensor, which means - the measurements should have a certain pattern (according to engine cycle)?

Re: let's choose an enclosure

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...

Re: 1998 BMW V12 engine M73

Indeed, what's the purpose? You want to sniff the signals? I'd suggest finding Haynes repair manual (if there is one for that car) - from my experience, it's the most extensive source of information. As for the video, I'd say it was more than 5 seconds for each operation. Have you checked your wirin...

Re: Sprut - A newbies try to design an ECU

What about the firmware? I doubt that rusefi will run on your microcontroller of choice.
I wonder, how difficult it is to reroute the board for a different connector?

Re: Sprut - A newbies try to design an ECU

you mean, expected freqency is 6.66kHz?
what's on that screenshot? how did you get that image? what are those red regions at 2kHz and at 15kHz?
probably, there is some noise from tappets and something else? How can you be sure that you indeed had knock events?

Re: rusEFI display

I would say, in my 1993 audi I have four servos driving my climate control flappers (which is off during probably half of my rides) and four steppers in dashboard (which works constantly). I had to replace pots in those servos to make climate control work, and it seems they've been repaired by previ...

it seems you have some prejudice against it. did you have some negative experience with stepperes in the past? I'm not sure about longevity of servos (at least the hobby ones) in such applications.

С другой стороны при игрищах с приборной панелью проблем не было.
Можно ещё попробовать отвязаться от питания авто, запираться от компа, оставить только vr датчик..

осциллограф же есть. но вообще глупо, что забыл анализатор захватить. покупать не проблема - проблема со временем.

я хз с чего начать и куда смотреть. завтра опять буду в гараже - я вроде и морально готов ставить инжекторный впуск, но смысла мало, пока не побежден триггер.

то, что другие входы не подключены - не должно же влиять на распознавание триггера?

с чего бы это он должен быть одинаковым? впрочем, я про изменения в частоте и говорю. vr датчик куплен лет 6, на улице за это время бывал наверное дважды. экранирован. доставать сложно и муторно. родных мозгов у двигателя нет - он на карбюраторе. речь о другом. потерял куда-то логический анализатор....

Re: Всякие глупые вопросы, терзающие меня

про ардуину - наверное потому, что на pd1 создается идеальный сигнал с одной и той же частотой, а хочется иметь возможность плавно ее менять?

хз как выглядит сигнал во время прокрутки.
как выглядит сигнал при неработающем цилиндре?
