1999 wideband 02 sensor conversion
I have been doing some reading on how O2 sensors work and why they are useful. My understanding is that the stock 02 sensors are NOT wideband and are more or less digital (either running rich or lean). I have quite a few bolt on’s, and after installing O2 eliminators with the new x pipe and flow masters it smells a bit rich and the car will kill itsself from time to time. I am in need of a new tune but i was wondering if there was any way to upgrade the O2 sensors to wideband to help feed back more accurate information to the ECU(not just a gauge). Obviously this would require a custom flash but I was just wondering if it has been done or if there is even a reason to do it.
Secondly, when you install O2 eliminators is that compensating for the lack of catalytic converters or is it just sending back "dummy" information to the ECU just to make it happy?
