I know absolutely nothing about 02 sensors, but have seen their benefits touted here enough to trust that they are the best way to go for getting jetting right. I have a number of questions about them, but would like to start with some basics. In response to a recent question on DCOEs, RootsRacer said:
I am going to have to remove the header from my car to have it re-coated (went with a local guy who came well recommended, but his ceramic coating barely lasted a year) and was thinking that this might be a good time to weld on a bung, just in case I ever buy a sensor or get the chance to hook the car up to one. For that matter, I may add one to my S3 and SIV V6 exhaust systems when the time comes, just in case. First though, I have a couple of questions: what the hell is a "bung" and where do you put it?
...If you can get your car down to west arvada and can weld an O2 bung on your exhaust system, I'd be happy to help you jet either setup.
