Help with LAMBDA setup and VE tuning 
Hey guys I'm helping a friend tune his bolt on 02 camaro. I followed the writeups on here and have the wideband reading 1.10 lambda when the afr is 16 flat outside the car. We did some logging and all the values were in the +9 range. I did the paste multiplier and then relogged and nothing changed. The scanner still read the same lambda errors.The log file is below but for some reason its not showing commanded lambda and lambda error. They were there though when I was scanning and got the error values. Here is the speed density tune I was using as well as the cfg file with all the pids. If anyone could look this over and let me know if they see anything wrong it would be awesome thanks...

I agree with Russ, your MAF DTCs are wrong and need to be no mil light or mil on first error. Also, your Lambda error PID should be % for units, not lambda. I had that wrong the first time I did it too and I ended up with a VE that was WAY off from what it should have been.
