Re: Help to choose right setup
In your example nothing should be inverted. Only if your stepper motor will move in wrong direction, then you should set inversion for SM_DIR.
Note: you need to connect a pull down resistor between IE and ground. 1...5k resistor. In opposite case VT1 will not turn off.

Re: Help to choose right setup
What resistance should be for spark plug cables.
If I use cooper cable and cut my lenghts I need then I need spark plug caps with 1,2,3 or 5kom resistance? Or it dose not mather?

Re: Help to choose right setup
At least, either wires or spark plugs should have resistance. 5k is Ok.

Re: Help to choose right setup
hi,
today I managed to start the engine with secu!
engine works very nice !
there are some things to fix, but generally very happy!
1. tachometer is not reacting . circuit with diodes and resistor needs to find right resistor ( I guess..)or use Hall_out
2. when I turn on ignition secu wakes up. fuell pump starts for 5sec. crank engine and all works, but when I turn off ignition engine still runs! had to disconnect secu from ignition wire........ Strange.....Or Im doing something wrong ....
and I need signal for CE +12v. so if i add 47k resistor between 12v and ce output is it OK?

Re: Help to choose right setup
YOu mean like this.
Could not get it working right with diodes. I got free outputs so Ill try hall_out

Re: Help to choose right setup
Yes, you need that resistor, because IE is a high-side output and has no internal pull down resistor.

Re: Help to choose right setup
Ok. I made circuit, but taho is 160 rpm secu 1200?
And ignition cable when i add small lamp to test if acc turns off it dose but without lamp dash gets acc off but engine runs

Re: Help to choose right setup
Try to change pulse width or set inversion check for that output.
