Hi All,
I have my wideband all hooked up and scanning properly. (I think). I am getting a crap load of knock at WOT and a few other areas. It looks like my trims and AFR are in the acceptable range. I'm not sure what I am missing in my tune!! Is there anyone who could look at it and point me in the right direction? I greatly appreciate any suggestions!! Attached is a copy of my tune and recent scan.3-3-19 long scan 2.hpl3-3-19 working afr adjust 4.hpt
