Hello Everyone,
I'm willing to provide whatever the board needs to help me.
New to tuning, but have been doing lots of reading. I'll get right to the point: (Gen 4 engine with Gen 3 PCM, 1999 LS1 originally)
I'm really concerned/worried about my o2 readings. The logfile attached is me getting close to finalizing the VE table (MAF Disabled of course). During Idle, one of my o2's will go full lean, the other full rich. Also, you'll see sometimes during acceleration or cruising at a higher rpm like 3,000ish, the same issue exists.
What else is wrong electronically, based upon the log? Aside from a few lean areas I need to fix in my STFT table.
I did lots of reading, and that's what has made me worried. This is a new swap:
New plugs
New wires
Used Truck coils
LS 427 Gen 4
Baby cam @ 235/244 .629/.615
Any direction or troubleshooting tips would be greatly appreciated. I'm kind of at a loss. The misfire code throws itself right away the moment I enable MAF. However based upon NB02's, the misfires truly exist?
Can any of it be attributed to an incorrect fueling table, or, am I looking at deeper mechanical issues or simpler ignition related issue?
Thanks everyone,
Andy
