Sierra Twink runs rough and dies

Hello!

I'm having trouble getting my engine to idle smoothly and respond to throttle input.
It dies if I touch the gas pedal.
I've had it running for about 30-60 seconds without dying at idle after adjusting the spark table to about 16-22 degrees at 1000-1500rpm.
Engine vacuum never goes below 60kPa, but no leaks.

However, now I'm back at where it runs for a few seconds and then cuts out.
Spark plugs are full of soot after a few cranks.

I haven't been able to get a proper read out of the wideband as it takes a while for it to start reading. (Been using this wideband before I installed MS so I know it works.)

Setup :
N9C DOHC engine
Megasquirt 1 V3
Td04-15T turbo
Motorcraft wasted spark coils from a Zetec
HT leads from a Zetec
373cc brown Saab injectors
All sensors are original except a No-name wideband gauge with a Bosch sensor.

I might have bitten off more than I can chew.
That's why I'm turning to you, friends of the internet, since I've lost my garage and have to sit in the parking lot enjoying the Swedish summer (Rain and 15c).
I've been going through the manual several times.

I'd greatly appreciate if someone could point me in the right direction.

I'll attach my latest datalog and MSQ.

Played around with the trigger angle and had it running for about 5 minutes with the spark fixed at 10 degrees.
Yet it still misfires and refuse to respond to throttle input.
I'll attach a new datalog and MSQ.
