Startup and idle issues - FD3S Link G4 plugin

Reposting here on the advice of Howard! Having some issues getting my FD going with a Link G4, spec is:

1993 car
T04Z
550/1650cc Bosch injectors (top feed)
MSD 6AL + GM twin coil leading ignition
AEM IGN1A trailing ignition
340lph fuel pump
Radium FPR
Link 3 bar MAP sensor
Stock ports

The car starts but the idle hunts really badly, the car also won't respond to throttle inputs. Throttle is definitely opening, I've got good fuel pressure, tested the ignition and each injector, haven't compression checked beyond the basic crank test. If I blip or hold the throttle nothing happens, it just kind of bogs. I knocked the master fuel up a bit and it seems to run better, with it at the standard 12ms the car would just stall. Will grab a video from my phone, but have attached logs and map. Map is basically just the base map, I've just added a wideband to the AN Volt 5 input. Any help greatly appreciated!

I'll be anything your entire issue is just base settings not being right. There are A LOT of menus in the link software and unless you have a startup map then you have configure everything yourself. Go one section at a time and make sure its all right. It should take quite a while

Is the base map not just a case of map/tps calibration and off we go? I'd have hoped that as the car isn't wild spec it should start and drive on Link's base map, even if it is a little rough.

I'll do some menu diving and FAQ reading, cheers.
