Hi guys,
I finally got back into the game after 2 years.

I would like to pass emissions(obd 2 test) while having ms in complete control. I know its simpler to put the stock injectors back in but thats no fun :)

I currently have MS doing fuel only. I have the stock injectors plugged in and zap strapped on the side of the engine bay. The only check engine lights i currently have are for no CAT and Too Rich and Too Lean.

I am going to put in a fake cat and put a o2 simulator on the secondary 02.

Could i put a 02 simulator on the primary o2 if i adjust it to display 14.7 afr?

Any other suggestions into fooling the ecu?
