What am I doing wrong?
Hello,
I have been working on a closed loop tune because I have put catalytic converters back on my vehicle and I have been trying to solve an issue which I suspect is being caused by something within the tune. When I a driving and I view the DIAG page on the WUD (EBL Flash), I see vertical red lines that run from top to bottom of the graph along with the graphed line. I remember changing something a month or so ago that made those lines go away, but I cannot remember for the life of me now what I changed. The red line correlates to the NB O2. I can also see the purple line (WB O2 AFR) which hovers between 13.8 and 14.3, I am targeting 14.2. The graph though is mainly taken up by the vertical red lines with less than equal wide spaces of the normal grey back ground. I tried to take a screen shot, but it was unsuccessful. I hope I am explaining it well enough. Thanks
Chris
