Is there a way to eliminate the o2 sensor? Is it pausible to use a wideband o2 to replace the oem sensor and have the wideband do all?

 

That's the preferred approach. Just wire the wideband signal into the O2 input and configure it for your wideband type.

Just to be clear, wideband O2 sensors require a dedicated controller. It's the controller output that gets wired into the MS.

 

that's exactly what I wanted to hear.
