Re: ВАЗ-2103 "Рыжик" (1977) :: Lada 1500 "Ryzhik" (1977) #37

*** Текущий прогресс по ЭБУ Hellen на процессоре Cypress. *** 1) Проблема наводок от катушек на РХХ. Была замечена проблема, когда на холостом ходу РХХ начинает самопроизвольно закрываться (не из-за прошивки), если хотя бы одна катушка даёт искру. Как оказалось, помехи шли по проводу управляющего ка...

Does it translate into "you'll need TO MAKE YOUR OWN pick&place files" or does it translate into "the extra files are available/will be available at XXX"?
If Guenther makes a final decision to pre-assemble his Prometheus boards at JLCPCB and if he asks for my help, I'll try to create these files.

Re: Hello there!

Most of the MS2 derivatives use just the same BIPs as the Prometheus does and you can just solder B to C and use the signal, but a buffer of driver IC would be the most elegant method I think. Yes, you can solder jumper wires instead of BIPs. I've used Prometheus with logic-level COPs just fine: !l...

Yes, that's true. If you enable this option, it will use batch fuel/wasted spark right after the first sync (until fully synced):
