Audi 5Cyl MS3 Sync Loss Issue

[dochka]

Hi,
Having difficulties running a MS3+MS3X on a Audi S2 5Cyl engine;
Triggers are Crank wheel 60-2 & Cam Distributor 1 tooth
I've installed MS3+MS3X on 2 previous same cars with no issues at all, both of them running full sequential fuel + ignition (5 coil on plug setup).
The problem is that the engine starts but then i get sync loss @ 1100 rpm and no matter what i dowith the pots, or by changing polarity, configuration settings, the sync loss persists...
I've even tried 2 Megasquirt units, changed a bunch of crank sensors, switched from flywheel driven 60-2 trigger wheel from a VW Polo 1.4L to a front mounted 60-2 crank trigger, same issue so far
Tried a 1K resistor in the v3.0 pcb, tried adding a 10k on line 24, all the same

It seems to not be detecting real teeth. First, try turning off noise filtering to be sure the noise filter isn't being too aggressive.
