Just bought myself a scanner and while going through the live data I noticed I was running anywhere between 20-30+* spark advance. I'll be perfectly honest and say I don't know anything in regards to this, or if it has any correlation to knock. The car is close to stock. It only has a few aftermarket parts which are, spark plugs one degree cooler, 180* thermostat, new down pipe and cat back, and a CAI. Everything else is OEM parts.
SO now that you got the background info, My question is if this spark advance is normal for essentially a bone stock car.
