• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Still getting knock with 3.8" pulley and exhaust mods

I understand that, but lowering the target is just going to make it richer since the add vs time/rpm is still working. You are already at 11 afr if not richer.

Log the PID "Commanded AFR" and put it in your scan screen or the gauges. That way you can see what the computer is calling for an actual air fuel while driving.

I'd lower the final timing by 1-2 and see what happens.
