Hey guys. New here to the community. I'm looking for some help with installing this wideband. Long story short. My daughter got in the car and messed with the tune on my apexi safc II. Now im scared tp drive the thing under any kind of load of fear it may be leaned out on my hi throttle map.

So my question is do i need all of the factory o2 sensors. It seems like a little overkill and it would prevent me from having to take it to my dads to drill and weld. I had an idea of splicing the wire from 2 to make one feed signal to both inputs. If that makes any sense. I did some research and found a forum about
it. But didnt know if it would apply to my specific car. Any help would be greatly appreciated. Thanks guys!

Stock computers don't like it when you take away an O2 sensor. Just do it right and weld in a new O2 bung for your new O2 sensor.
I DEFINITELY would not try to run 1 O2 sensor with the stock computer plus an aftermarket wideband controller... that definitely will not work. Best case your readings will be off... worst case is you will blow the sensor, computer and/or aftermarket wideband controller!

Which after market wide band O2 controller are you going to use?

I used the innovative contrroller when I converted my old mercedes to efi with megasquirt.
