Hey whats up? new to the forum

I was just wondering If any one had a o2 simulator installed in thier gs 400 or 430. I just installed one but the check engine still comes on after 15 minutes.... I'm looking to remove the cats and install a borla exhaust
any thought? ideas ?

thanks

 

I assume this is that unit from ebay that claims to fool the O2 sensors on your car and supposedly give you 20+ hp?? If so, get that thing out of your car ASAP and get your money back. Read that seller's feedback really well.

If this is something else, my apologies.

Good luck

no this is a simulator that, allows you to trick the ecu into thinking that the post cats sensors are stil their signal so the check engine light will not como on... I know what you are talking about, I have seen it on ebay but thing is another thing...
The thing is this the gs 430 has the OBD II emissions and they have a pre cat sensor and a post cat sensor. the post cat sensor check up on the cats and assure thet they are doing thier job.. with the simulator you can get rid of the post cat sensors

thanks

 

welcome,

If you haven't already, use the search feature and I'd bet that there are others who have posted about their experiences with this stuff. The search box is golden for all sorts of information. There's also an entire, separate Engine and Transmission section within this GS430/400/300 forum (up top on main GS forum page), which might provide more help. In the meantime, my personal advice would be to pull that thing out until you do more research on its effects.

Good luck!
