    Default quik question?

    Ok i know its been asked a million times, i have been trying to run down and get an O2 bung welded in for my lm2 sensor, well i happen to glance at it while dropping the oil and changing the filter and i see my post cat O2 sensor in there, now to remind you i have one in each header then that one installed and the last one with a fastman simm, can i just put that one on the frame also?

    If you have a cat, you might as well leave the post cat sensor in the pipe. If you dont have a cat, then hang the last sensor from the frame, and feel free to use that bung for the data logger.

    Don't put the data loggers sensor after a cat, though, and for accuracies sake, the closer to the collector the better.

    I thought 99's had 3 O2's? Maybe I'm wrong. Either way, if you have an O2 sim and it's working for you, just leave it alone.

    For the data logger, if you have an open bung- use it! The closer to the collectors the better, but it's not a huge deal. As long as there's no cat before the sensor, you're good to go

    yea 4, one on each header, then the 3rd on pass. side and the 4th one on the frame with a simm, i was asking about removing the 3rd one and using the bung but that will be a no go!

    Ok, yeah, if you have a pre cat sensor, it stays in the pipe. But if you don't have a cat, the fourth bung should work fine for the LM2.

    If you need a bung put in a tight place, call Sharp's in Moxee. Dave can cut and weld in bungs in places you wouldn't think possible. Best exhaust guy around without a doubt.
