    wide band o2 sensor

    So a lot of people r telling me to replace the up pipe for added performance, cool, gonna do that. the question i have is about the exhaust temp sensor in the up pipe. i've read where u can just block off the bung for the sensor and do a 2.2 kohm mod for the wiring, ok that i can do. now can i install a wideband o2 in place of the sensor for an air fuel gauge such as an innovative motorsports gauge instead of blocking off the bung.

    You cannot place a WB02 in the uppipe. It must go behind the turbo if you have one, and must be at least a minimum distance downstream from the turbo. The manufacturer's instructions that come with the gauge will tell you at what angle, distances, etc. to mount the gauge.

    The usual place is in the downpipe, and a lot of aftermarket downpipes come with an extra bung for mounting a WB02.

    Right. Wbo2 does not go in the uppipe. It goes on the dowppipe after the turbo, but before the cat (if there is one). Preferably not too close to the turbo (the heat will wear it out quicker), but depending on the downpipe your distance can be limited. I highly recommend the AEM A/F/R gauge and UEGO sensor.
