Spec B Posted July 20, 2009 Share Posted July 20, 2009 Are you using the stock 02 sensor or a wideband 02? Link to comment Share on other sites More sharing options...
biz77 Posted July 20, 2009 Share Posted July 20, 2009 what? Are you hard of sight? HOW ARE YOU MEASURING YOUR AIR FUEL RATIO? What I'm getting at, is if you are using the ECU to datalog the AFR, then those numbers in boost are completely inaccurate and therefore useless.

EvilCamaroSS Posted July 20, 2009 Author Share Posted July 20, 2009 Yes using the AP. A wideband 02 will give you more accurate results but, the factory 02 is going to give you a rough estimate. I'm not going to go out and get a wideband on such a mildly modded car, such a waste. I don't even have a wideband in my SS and that's cammed, full bolt ons and tuned just fine.

Spec B Posted July 20, 2009 Share Posted July 20, 2009 Stock O2 is only good when you are not in boost...once it boost it gets pretty inaccurate. With that said...stage one with a drop in might run a little lean, but nothing to worry about. Link to comment Share on other sites More sharing options...

At anything other than idle and cruise the factory O2 is useless. You see constant 11.15 in your logs because that is the limit of what the sensor will read and the ECU will report. If it is a Cobb tune you can rest assured that it is running pig rich. Link to comment Share on other sites More sharing options...
