Do I need the 2nd o2 sensor on my '99 teg ls, the one after my cat? I plan on running a 3" straight through pipe off of my downpipe, no cat, just muffler. I'm runnin uberdata and I think I recall there being a setting that I can disable the 2nd o2 sensor, is this correct? If I don't have the 2nd o2 sensor will I be able to run in both open and closed loop?

Anyone know?

 

you can disable it... just remember you need it to pass emissions when you convert back to obd2

There's no emissions here. They just check for stock mufflers.

 

hey..if you remove your 2nd o2 sensor ill buy it off you.....i need to pass emissions...heheh

 

when goin obd1 you do not need th second sensor the computer doesnt pick it up

 

As I recall, the obdI ecu doesn't use a 2nd sensor at all. Which is what you converted to when you went with uberdata.

No, there is a conector that you can use to unplug it. Where the wires go through the body of the car there should be a rubber plug, pull that out and you'll see the plug I'm talking about.

 

so true, thx a lot lol! i was about to cut it ehehe
