Go to the Fastman for O2 Simms:

They are hit or miss. Sometimes they can cause your tranny to go in to limp mode.

Which O2 sensors are you planning to use the simms on? If it is the post cat, have you tried to zip tie it to the frame?

From what I read from a couple of people, the tranny will go in to "limp mode". Basically it acts funny but I can't remember what exactly happens. I am not sure exactly but hopefully someone will chime in that has experienced it.

I have long tubes and no cats on my truck. The engine light is on but no performance loss at all. I have the motor apart right now. But I read that some people leave the first o2 sensor in and zip tie the other one to the frame of the truck. All the sensor needs is a reduction of airflow to not throw a light. Some people say that it works and some don't. It is worth a shot, I will let you know how it works when I get my truck back together....

Also I forgot to say that the ones that you can buy on ebay work good too. Just type in "o2 Simulator" and look at what comes up. I had the ones that you put on your o2 sensor and then put that in the o2 bung. It just pulls the sensor out of the exhaust pipe and has a little piece of cat. material in it to help with the light. They are only a couple of bucks too.
