Default MSPNP 90-93 Miata 600cc injector problems

I installed my DWerks 600cc injectors today. I did the settings in tunerstudio where i punched in the engine cc,injector cc and how many cylinders.

I had a 205cc org fuelsystem before, i have added a 255 walbro HP pump and today the 600cc injectors.

My problem is that my car goes so rich that i can't drive it or get it tuned:\ I tried to divide the crank pw numbers by 2.97 (approx what the differential in injector size is) and punched inn all the numbers . Did not help me at all - car wouldnt even start, if i switched back to the basemap that came with the ecu it starts but runs like crap. It can be driven.

I tried to alter these ASE settings also but didnt see any difference:\

What am i doing wrong?

Setup:
MX5 1990 1.6 - JRSC @ 60/150mm pulley - 2.5" exhaust - MSPNP ecu with extra software. Im running a registered Tunerstudio software. Norwegian Blyfri 98octane ~ 93octane in the US as fuel.

I took the car for a drive earlier today and when i get boost i get a hardcut on the fuel or ignition. Tried roadtuning it a bit, but it wont run as i did with the 205 injectors and only the 77.5mm nosepulley. I hate when the car dont work as i should since i need it to get around..

Please help me with this guys!
I can upload a log from my road run if needed, and pics of the map as it is right now - the way it is now i atleast get to the store and back home.

Here is the map and the logfile from earlier.

I cant get the car to start on this when i turn the engine off.

So i have to use this map to get it started:\

Your acceleration enrichment also needs to be dialed back - it's dumping in way too much fuel, probably triggering too easily, and seems to be implicated in most of the running rich in that data log.

Use the Acceleration Wizard. For more detail, see here.

I think i managed to fix this: ) The car feels much better after some tweaking I'll post some logs and a copy of the map tonight so you guru's can see if its starting to look ok.

Thanks for the help so far
