Re: Широкополосный лямбда зонд + контроллер

Даташит я пока не нашёл, но я нашёл вот такой пример кода - http://forum.arduino.cc/index.php?topic=144703.20;wap2 - и я вижу там что-то про ПИД управление нагревательным элементом. Так что есть вероятность, что нужно нагрев программировать самим?

Re: wideband AFR sensor interface

I've created a blank project & copied the schematics, looks like the CJ125 would need to be extracted into a separate file https://svn.code.sf.net/p/rusefi/code/trunk/hardware/CJ125_board/

Re: launch control

It would be tough without a car, at least you would need a discovery board with a couple of potentiometers to simulate sensors, or, probably a better option, you would need to add 'mock' clutch up/clutch down/VSS speed into the simulator the way there is mock voltage for analog sensors in simulator....

Re: Honda/Acura K-series ECU tuning

I was playing with the same idea but for the Mazda ECU - traced a lot of wires etc. The killer in case of rusEfi is the fact that our stm32f4 chip is 3.3 volts, not 5v as it should be in an ideal world. It's a loooooong story, but for all the pros of stm32f* we have to pay with the 3.3<>5v bridging ...

Re: Текущий прогресс по прошивке.

Новая команда
blipidle IDLE_POSITION DURATION_MX

например
blipidle 90 3000

открывает КХХ на 90% на 3 секунды. Команда полезна во время настройки обогащения ускорения.
