if you use only 1 cam sensor it means the ecu only get one signal every 2 engine revolutions.
Correct. Disconnecting G1 and grounding that output pin will make the distributor output a 12/1 signal (12 per crank rev, and 1 per cycle). Not 12-1 (12 per rev and 1 missing per rev).
Your settings would be Dual Wheel, Primary Base Teeth 12, Secondary Teeth 1. This would allow it to know cycle (cam) info, permitting sequential injection.

Correct, but it would technically be a 12/2. "+" or "-" indicate added or subtracted teeth on the
same wheel, while "/" separates crank and cam signals (360°/720°) This will not allow sequential, as it sees a "cam" signal every crankshaft revolution. Speeduino may be confused as the two "cam" signals are so far apart, as it is expecting to see both /2 'cam' signals on the same crank 12/ revolution. So, 12/1 setting may actually work if using
both G1 and G2 sensors. I have not tried that, so I can't say if it will work for sure.
I would suggest trying the method posted earlier — disconnecting and grounding the distributor module output for G1. This could be as easy as moving the G1 wire from VR2+ over to VR2- for testing. Make a trigger log (if you have registered TS) or an oscilloscope image of the signals to post here if possible.
