Need an EMU map for 1.8 550cc and 12 psi

I am in the process of installing a '99 1.8 with ubercharger and 550cc injectors into my '92. I will run the 1.6 ecu and sensors along with my EMU and no AFM. Anyone have a decent fuel map to start with? I should be at about 12 psi.

Still have the map you were using the the MP45? Why not start with that one and change the injector size. You'll no doubt have to tweak it a bit to compensate for the extra displacement and flow- lie to it slightly and tell it that the injectors are smaller than they really are.

BTW- did you ever install a WBO2 sensor?
