Od wersji 20241117 rusEFI dla LC ECU 56 zostały dodane opisy pinów w TunerStudio, czyli przykładowo zamiast “PA4” jest po prostu “Analog in 1”. W związku z tym trzecia kolumna “Pin STM32” jest zbędna i została przeniesiona na tą osobną stronę, dla starszych wersji oprogramowania. W przypadku wersji 20241117 i nowszych należy korzystać po prostu ze strony https://lcecu.pl/pl/pinout-56

Pin 4 sondy LSU 4.9 należy podłączyć do +12V po zapłonie, a więc do tego samego źródła, co pin VBAT +12V.
