well, today my engine decided to start knocking so in order to recreate the situations you can see that it was not like a 3rd pull at WOT, it's sporatic low rpm driving. I still have some tweaking to do up top for WOT, but honestly that can wait, tomorrow I have a 1000 mile road trip and care more about part throttle issues and will take it easy on the car. I was getting knocking below 3500rpms in 1st and 2nd and sometimes 3rd. This just really started today. I switched to just the base high-octane tune and the same thing happened so I don't know if there is some bad shit going on inside my motor or if I got some bad fuel this time. So could it be that ignition needs to get pulled back or maybe the Mobile gas i got instead of the BP that I usually get is messed it up. Someone please tell me what is going on? I didn't save the datalog for a WOT run, but there is zero knocking under those conditions, only during part throttle. I would post the datalog that I did for part throttle, but the file is too large even when i compress and zip it for some damn reason. But when I switch from the 30 degree to 20 degree high speed cam angle I went from zero to 9 knocks.
