wideabnd o2 question?
Looking to add a wideband o2 sensor and gauge in my 87 S4. Can i take out the o2 sensor and replace it with the wideband, or do i have to add another bung for the wideband sensor?

For the OP, you'll need the controller unit as well. You cannot put just the 5V w/b sensor in and expect it to work. In fact, my suggestion, if you'd like to run a wideband in the car, is to get an actual wideband product with sensor and gauge and run it in a second O2 sensor bung in the downpipe. That way you can keep the 1V narrowband sensor in for the EFI system's closed O2 loop function.
