The Australian FS is OBDII as well, not sure how that interferes with the FP. Should just be able to swap everything over I think. (Not my area of expertise tbh and famous last words no?)

Yeah AFM = Air Flow Meter. Which can either be MAF(Mass Airflow Meter) or MAP (Manifold Absolute Pressure). Our cars have MAF

So youve used something to measure the oxygen levels or all smell?

My point is that the stock ECU AFAIK doesnt take into account volume of fuel injected but duty (in closed loop) so in closed loop an FP ecu will pump more fuel then an FS ecu would (at least in theory) as the FP is pumping at a certain percentage.

Which means based on this logic that the problem has to be air related. Try using FP MAF with the FP ECU see if that helps you out somewhat. Youll want the FS ECU in there eventually anyways IMO.
