After taking a little break I returned to my project and meanwhile I am a bit further with a repurposed active Golf 3 coil which seems to work ok.
However, strangely when the engine stops the ECU still sends ignition and injection signals at increasing speed. See attached video. I have tried with a 4.7k resistor across the VR lines and also enabled aggressive filtering in TunerStudio.
VR- is connected to ground, VR+ is connected to the pickup coil.
I have no CAM sensor, so nothing is connected there. Do I need to ground HALL_IN? or bridge SJ5? Perhaps the noise is picked via HALL_IN?

Another question. As I have no CAM sensor I thought that 2 squirts per cycle would be best. However, when I select 2 required fuel (ms) is set to zero and I can't change this to anything non-zero.
Any help is greatly appreciated
