Thank you very much for the blessing from a distant friend!
Yes, I am still groping for mode 8 without the camshaft sensor, which is not going very fast.
Our rules allow camshaft sensors, but I don't have any experience with how to install camshaft sensors, so do you have any information or experience to pass on?
Thank you very much!

It looks like your capture has 22 teeth do you have this set up in the number of teeth for REF?

Are you using falling edge for the REF sensor?

Pull the spark plugs out and do another capture.

While the spark plugs are out see if it syncs up.

Thank you very much for your help.
Yes, I have set it, but now I am using the rising edge trigger, using the two-stroke mode 8, but the problem I met makes me unable to understand.
(1) in the first case, when I pulled the spark plug from the cylinder and started the ignition without the cylinder pressure, I saw that the ignition and fuel injection were normal.
(2) the second situation is beyond my understanding. When I put the spark plug back into the cylinder and started it with cylinder pressure, my ignition and fuel injection were normal when the throttle was fully closed, but the ignition and fuel injection were disconnected when I opened the throttle.
I have ruled out the throttle position sensor. I think there will be no ignition when there is air coming into the cylinder from the inlet, because it is normal to fire and spray when I plug the throttle valves of cylinders 1 and 2 or 1 and 3.
I think there's something wrong with my setup,
If you can help me, can you give me your email address? I will show you my current Settings.
Attached is a crankshaft signal diagram I collected.
Thank you very much!

Looks like you changed the wiring for the sensor from the original capture.

Your problem is the cranking consistency, for some reason the crank is decelerating/accelerating even with the spark plugs out.

By opening the throttle you are putting more load ( by introducing more air) on the starting system making the REF signal even worse. In this case the ECU cannot detect the missing teeth which is why the injection and ignition disappear when you open the throttle.

Fix the starting system.

So on the boot side I can change the Settings or what's on the hardware
