i have 98 c5,202 valves, hot cam, lgm longtube headers, and just got my hp tuners loaded wondering how to shut off o2 sensors. Maybe the there is some that could look at my first scan file and tell me where to start. PLEASE HELP!

 

take this to the "pcm tuning" section....

 

Going to PCM.

 

go under DTC's and MIL status.. look for Bank 2 of your oxygen sensors.... go off
aka NOT reported setting
