If I have modified the Stock CA18DET AFM can I compensate for this in the niztune software and if so how?

How have you modified the AFM?

You can change the VQ map for voltage/load calibration and/or the Injection Multiplier (K constant) for increased total flow changes

Sorry got carried away with the dremel tool.

But It was just bell mouthed and polished

The vqmap is the total load % vs voltage (0-5) that is calibrated by Nissan for each AFM. This may need changing but I would start with the injection mulitplier first

The K constant would be increased by the % of extra airflow you have introduced to the AFM
