You need to change the fuel injector tables, cylinder volume, volumetric efficiency, and base running airflow numbers. There may be a few other small ones, but these are the cruicial ones to make the engine run correctly, especially the injector and and cylinder volumes.

Are you using the blue/green connector harness from the LQ9, or a red/blue harness?

being debated right now, the harness off the lq9 is in great condition, where as my ls1 harness looks aged, and i had to repair some broken wires on it so its not perfect, though i'm not sure if its just plug n play...
