So the more I read about this the more I think I'm just going to replace one of my pre-cat O2's with the PLX wideband (PLX SM-AFR which uses a really standard Bosch LSU 4.2 sensor). This means I've got to run the 0-1V output from the control box to the input of the old O2 sensor - no big deal. The part that doesn't really appeal to me is the heat generated by using a 20Ohm 10W resistor on the O2 heater circuit - so you don't pull a CEL. Well, since my car has an Active kit and tune on it - I don't think it cares about this anymore Has anyone tried just not hooking the heater circuit back up?
