from Cyl. 1 (no misfires) and Cyl.2 (shutting off).

Maybe anyone sees a cause - i don´t.

If i messure peak to peak, then i get always only half of the real rpm
in the bottom right corner from the Pico-SOftware, is that normal ?

The peak pressure in cylinder must be at 15,7 bar(this is a calculated value for the compression ratio 10,3 and specific heat ratio 1,3) without ignition...
And yes is normal to get only a half of real RPM because from peak to peak the crank shaft have 720*(2 complete rotations).
