And scope the outputs of the sensors and at the ecu. Could respond very differently in an dynamic situation eg running engine.
I think that the thing we are missing is either a damaged or crossed wire or a sensor that is not doing as you expect.

ECU ISSUE FIXED YESTERDAY!!!
As it turned out a forum member Nik was right in pointing me at the direction of trigger wheel to sensor gap.

I measured mine and found gaps:
#1 - 1,1mm
#2 - 1,6mm
#3 - 1,1mm
#4 - 0,6mm
So the maximum allowed gap difference between adjacent teeth is 0,2mm and mine was 0,5mm! As this is not a small difference I decided to follow trough and try to exorcise the demons. I used a file to shorten the 3 teeth that had the gaps narrower. Installed back the trigger wheel, measured again, and a bit more filing later the gaps were all at 1,6mm +/- 0,05mm. Then I narrowed the gap to 0,9mm.
After a re-installing the auxiliary belt etc. I swapped the ECU to the OE one and fired her up. Everything started normally and the moody lady seemed happy to rev above the magic 2000 rpm mark where that illusive barrier lay beforehand. I reassembled the rest of the car, installed back the GC recommended spark plugs and went for a test drive. It looks like the problem is fixed! I got the car up to 5000 rpm with no problems. But as it was already dark the local roads became a popular meeting ground for deer, rabbits and other suicidal animals so I decided to stop with experiments for the day.
Thanks to everyone that helped with their advice! It remains a mystery why this gap would cause one ECU to fail and the other have no problem with it.
I still have a slight wobble in the pulley:

Not really sure what to do with it but I might just have to let it be...
I will now raise the boost pressure to the 1 bar that it is suppose to be. I am currently still running it a 0,5 bar.
I am thinking of installing a WB lambda. Any recommendations for a tight budget?
Hi, sorry for gravediggering. But i meet exactly this problem today. Thanks for this thread.
Gaps was 0.8/1.15/0.8/0.6 , wobbling pulley, cat ecu runs no problem, older non cat cutting out around 2-2,5k.
I never tested it at WOT yet.
From which manual is the posted printscreen? Critical information.
