Now I installed the VR circuit,
as I have this on my board,
now I get this while cranking:



I sometimes get this after switching on the MS.
:


Should the CAM in settings set to off or on?

I tried this with these settings:

Ignition output capture: Rising edge
Spark output: going low
Spark hardware in use: LEDs spark

you still have no cam input.


When using the VR circuit, you need to use the cam in on the ms3x board to match the polarity. With the cam still on js10, I don't think you can run the VR input.


regardless of this, youre still not getting a cam signal at all.

OK, so I have to rewire it to your setup or get an MSX board.

regards of VR to opto, without the Ms3x right now, the cam signal should be going into JS10 with a pull-up with a 470ohm resistor to 5v to at least get a signal.

Ok, Makes sense.

So I put a cable from VRIN to JS10 and I put the 470 ohm resistor from JS10 to 5V,
Same as you did in your setup.

Then the signal should be there?

vrin/opto in is your crank.

that's becuase your crank is outputting a falling edge signal and cam rising edge.

you could try switch your ign settings to the alternative one...i cant remember if that works. but those red lines represent where the MS was expecting a signal.

if that doesnt work, you need to revert back to the opto in for the crank.

yeah you gotta put the crank back on the opto circuit.


so:
tachselect to xg1
TSEL to optoout
top of c30 to 5v
and d1 and d2 are open.
