Solenoid flyback diodes? Idle solenoid? #18

Closed andreika-git closed 3 years ago

andreika-git commented 3 years ago

Do we have at least one solenoid in this car? Maybe the idle valve? Then we need flyback diodes for them like on the other boards: image Currently I don't see any of those on the board.

Maybe we should also use a separate power MOSFET for idle actuator as in HellenNB2?

@andreika-git do we have documentation for current limits of

Shall we rename OUT_LOW1 to OUT_LOW1_RELAY or OUT_LOW1_LOGIC or OUT_LOW1_LOW_CURRENT or something to make it more self-documenting?

B5819W and separate power MOSFET like https://github.com/rusefi/rusefi/wiki/Hardware/Hellen/hellen72-d-schematic.pdf same as on injector output channels just manual schematics

@Qwerty-OFF can we close this one?

Qwerty-OFF commented 3 years ago

Yes, we have good diodes for IDLE (2 wires), VVT and I don’t know why for EVAP
