Re: 02 sensor numbers (Kehrer923)
At WOT the 800-900 range is good..
Here's an example.. please disregard some of the readings (AFR, MAF Hz, Knock, and a couple others as this is an LS1 program used on an LT1).
This is a WOT reading at 119mph. Look at the top graph and the top right numbers for O2 readings
..and here's a look at O2 readings at 70mph cruise... notice that they jump around constantly... That's a sign that they're working well.

Re: 02 sensor numbers (Kehrer923)
At normal driving in closed loop the O2 sensor voltage is suposed to cycle back and forth between 100 and 900 (looks like a roller coster) If it stuck at 800-900 there is something wrong or the O2 is getting heated enought to get into closed loop.

Are you sure you have heated O2s? 93s came with 2 single wire O2s. If you have converted to heated units, were do you have the power lines run? :crazy:

Re: 02 sensor numbers (honas)
At idle a Autoxray scan tool read my drvier side sensor reading was bouncing up and down from around 100 - 800 that's normal. The passenger side sensor was flat lined at .010, that indicated it was not functioning Low Voltage circuit condition.
