It is easier to me to plug it directly - is there an avantage to drive FP by speeduino?

I have my MAP, TPS, IAT working.
Now I try to find out how to make run Trigger - power supply 5V, pullup resistor ON, I am plugged with TRIG / PRI+ on the output from HALL sensor - I have still 5V there...
GND of hall connected to general GND.. should I connect it to PRI-?

yes, the fuel pump will stop when the engine stops. my limited experience is that inertia switches switch when you don't want them to and don't switch when you do want them to.

Nobody knows how to handle hall sensor?

I see - power supply 5V
signal to PRI+
GND to commun -

but
with JP5 in place I have 1,44V at PRI+ with or without metal contact,
when I remove JP5 i have 1,05V at PRI+ with or without metal contact,

JP5 is for the cycle (cam) sensor input. JP4 is the pullup for the crank sensor input. ;)

It is acceptable in most setups to install both JP4 and JP5 if only using one input. This pulls the unused channel high, preventing the floating input from causing false triggers.

Hello I usually use this sensor in my projects.
It is a HALL sensor used in some VW models.
I'll leave here some images, including the correct connection of the pins.

About Jumpers,
I don't have much affinity with NO2C's hardware, but analyzing the diagram and considering that it doesn't have a VR conditioner installed:

For CRANK input
JP4 - Pull up crank (leave it connected);
JP2 - Use HALL position;

For CAM input
JP5 -Pull up CAM (leave connected);
JP3 - Use VR or HALL position, it doesn't matter if you're not using a CAM sensor.

Hope this helps.
