Now I need to make an ignition and fuel map ...
I found another my mistake ... my trigger wheel location on (power takeoff - the output shaft) and that means trigger wheel spinning Counterclockwise :( :( and that means right now all mirrored :(

Engines are supposed to start if
1) fuel
2) spark
3) compression

2. Spark yes
3. Compression good

I'd say ignition timing could be wrong?...
what are those red and green dashed lines? what's no_pin event in the bottom?

I like that as a moto. "rusEFI, don't touch your sexy exhaust" I think that be a great bumper sticker.

I installed the CAM sensor (Hall type)...
the sensor is powered by 6 volts ...(separate power source)
I make a couple of screenshots ...
I think that CAM sensor shows me the backward ...
or am I doing something wrong ...
in TS VVT position guage indicate 610 (what that mean ?)

Both images show only one VVT cycle. Would be nicer to see two or three cycles - to do that, please increase sniffer size on the bottom of the engine sniffer pane.

VVT input does not count like "cam" on our trigger page :( It's impossible to understand unfortunately but you need to say "4 stroke without cam"

Maybe I should simply prohibit BMP pictures because this 3Mb size versus 30Kb images is just painful.

Looks like everything works as expected?
