link ecu supercharged 350z

hello Im new to tuning, and having issues getting my afr to line out. its very jumpy and would like to get smoother. attached is the ecu file

thanks for your help.

Can you explain a little more about exactly what issues you're seeing? Do you mean that your AFR is inconsistent in a single cell? Or are you having trouble getting a smooth AFR plot during a WOT ramp run? What are you using for a wideband? I see you have this wired into an analogue input. Are there any modifications performed to the fuel system?
