I have read a lot of engine tuning books (apparently not enough) but i cant find this anywhere

If you get a wideband O2 sensor does this provide feedback to the ECU or is its only use for tuning?

basically my question is, can you take out the stock O2 sensors and just replace them w/ wideband 02 sensors and have everything remain good

FYI this is going to be on a GTO w/ an APS TT kit w/ cat delete

 

The Innovative LC-1 can do this. The HPTuner forum covers this. I think the innovative forum does too.

 

k thanks
