I was wondering has anyone tried using an O2 simulator on a GS400? Everytime I search it is mostly about the GS300 and IS300 wiring diagrams. I am looking to purchase the universal dual output O2 Simulator from o2simulator.com but I don't want to buy something if I can't even wire it up

 

Post cat right? I made a circuit that was pretty easy to make to bypass the post cat.

Check my DIY site for the wiring diagrams for the ECU. I have diagrams for both the GS300 and GS400

did you ever get this? did it work for you? and what reason were you putting it on, was it cause you are going FI?
