Weird Knock Retard ... Any ideas
If you look at my scan file, I get this high KR at low engine speed and throttle positions. But if you compare it to the base spark table, there isn't that much timing to cause a knock. The sensors are new since I damaged one and the other was corroded. Everywhere else this isn't any KR problems. I obviously can't hear the engine knock with a dual 3-inch exhaust. Is it my engine combo making the PCM crazy? Should I be concerned?
