Help: PLX M-300 Wideband Just bought the M-300 wideband and need to know how to wire. Is it better to have an additional bung welded over NB simulation? I don't think any exhaust shops around here weld SS. I would rather simulate NB if it will not create tuning problems between banks. What wire from the factory o2 harness is the signal that my WB (NB output) hooks to? What do I use for ground to the Flashscan box? Any ground? I do want to be able to data log. Are there any other wires I need to hook to in the factory o2 harness? How have you guys wired these, did you use the heater circuit to power the PLX controller or just a 12v switched source in the car? I did a search but I did not find enough info on this and the instructions to the m-300 are vague.
Thanks again,
Thanks again,
