Alright, so I have two basic questions. I have a 2003 Silverado 5.3L and I've dialed in my main VE table and I'm very happy with the results. My first questions is I've followed the tutorial on AutoVE tuning and when I put the tune into closed loop/speed density my commanded vs actual AFR are completely off. I'm assuming I've screwed something up or the tutorial is missing something. My second question is once I get it into closed loop/speed density what table to I use to command the AFR in, basically how do I tune it? Thanks for any help, I'm pretty new to this and I need all the help I can get.

If you are using a custom OS, from table [B3647] you can command a value that isn't B3601. What you mean by "Completely off" is a little vague to guess a reason. What are the fuel trims at? Are they constant through the whole load range? What is he AFR? Could you post a log and a tune?

Post logs.

Also, what fuel are you running...?
