ltn Posted February 10, 2006 Report Share Posted February 10, 2006 Hey i was just wondering what the optimum fuel ratio might be on a 02 avalanche. Cause i have the predator and im looking at the o2 sensors one bank one and wondering what the numbers should be at. I read the post about the predator 101 but that was for a f-body i believe, are they about the same for trucks. thanks Link to comment Share on other sites More sharing options...

TurbochargedBerserker Posted February 10, 2006 Report Share Posted February 10, 2006 For WOT? There is NO magic narrowband o2 number for WOT - you need a wideband. The range at WOT is outside the range where narrowband o2s are accurate. Idle & Cruise? 470mV but you probably will never see this due closed loop.

zippy Posted February 10, 2006 Report Share Posted February 10, 2006 14.7:1 under anything that's not in power enrichment and 12.7:1 roughly during power enrichment if you're naturally asperated. Link to comment Share on other sites More sharing options...
