Is a o2 simulator needed with aftermarket exhaust systems/testpipes to prevent a check engine light when the catalytic converter is removed? I sell o2 simulators to the import crowd and am wonder if I should begin marketing towards the GTO crowd as well. The reason I ask is because I've been helping my Dad modify his GTO so I'm starting to get into them (also enjoy driving it too, put on almost 500 miles yesterday!).

Peolpe say that you can tune them out. I have a Diablo tuner and all I can do is clear the codes not turn the check engine light off, so I have o2 simulator.

it is posible to tune it out, BUT you need a high end programmer to do so. Or a good tune from a shop with a cpu program for it ie. HP Tuners programer

I recently used a one on a Sentra SER-V and another on a Lightning. They're a pretty clever device since I noticed that it sends a signal that varies from .18 volts to .25 volts. I made one mistake when I wired the first one by leaving the O-2 sensor out of the car. I quickly got a SES light when the OBD computer said "hey, the O-2 sensor is missing". Wired it back in and tie wrapped ythe O-2 sensor to the frame. I di it for off road use only of course. But I also posted a thread on the Lightning forum about how well it worked. For The price? What a bargain!

I am also looking for O2 simulators for my '04 but I have been told there are none available for it. Anybody knows different?
