Hey I was wondering some things regarding wideband tuning. Why would they put a probe into your exhaust pipe downstream from the cat? this seems like it would be beside the point to measure o2 content after the cat? Also, if I was to install a UEGO, why do people say that the sensor will burn out quick, the bosch sensor was used on lean burn civics in canada, and I couldn't see them putting a sensor that will die like at 10000 miles.
Also, when using the downstream method, how accurate is that, it doesent seem like it would be that accurate unless you are running w/o a cat.
