Try 10-20k resistor in series with cam sensor signal..

Tried 10k-20k-30k, does not help...

Try to change cam#2 trigger edge from rising to falling.
Check if shields of crank and cam sensors are connected to ground (only at one side).

Ok
change trigger edge from rising to falling - became even bad
shields of crank and cam sensors - check tomorrow

try to get the cam cables for it self and not in the rest of the loom... is it only on 2k you have the problem?

check on emu scope how near is the edge of cam signal to edge of crank signa.

Your scope signanl looks good.
Please review your wiring (grounds and shields)...

wiring connect correctly...
if sensitvity switch RPM is ON 2000rpm - engine running good, but in the transition 2000 Rev. failure, above 2000 - all is good...

I had similar problem.
Resistor recomended by Jakub helped, but didnt remove the noise completely.
New high quality shielded cables from cam and crank sensor to EMU helped for me.
DOnt forget, the shielding must be connected just on one (emu) side, not on booth sides !
Also be aware to go near to transistor units, ignition coils etc....

Could you try to set sensitivity switch for example for 500-600 RPM ?

tried, ignition ok, but no idle...

The problem is solved.
Set sensitivity switch for 500 RPM.
Correct primary trigger angle for 37.
Correct ignition map.
Correct idle map.
Engine running very good!
Thank you all
