OK,
I bought the beginners guide and it was aswesome imo. I went straight to to the supercharged section. I have an 03 LS6 with the complete maganacharger kit. I moved t a 3" pulley and a gatorback with a higher tension tensioner. Everything looks great no spark knock at all which I find is weird. It runs incredible and its driven dailey and tracked on the weekends. Same tune. I have an AFX wide band that reads correct. My LTFTB2 is at 15 and my LTRTB1 is at 7
and STFTB1 is -1.8 Bank2 is -.7 The O2 sensor is 152MV on Bank 2 and 664 on Band 1. Is this just a bad o2 sensor. I ran 10 gal of aviation fuel and toped off with 91 octain because thats all we have around here. It was real gas. I found out that there was lead in the ave gas would this knock out an o2 sensor.?
The car ran incredible at the track it was a road race coaurse. However when I got back to regular driving and filled up I got the old P0430. I know I can turn the backs off but that is not what is causeing the front O2 to read like that is it? Is thsi a tuning issue or a bad o2 sensor? Sorry to ramble. Why am I not getting any Spark knock? I know you want to avoid it but really none at all? Thanks for the help.
