Curious as to how aggressive you guys are having to get with the knock sensor threshold tables? Also, when logging the knock voltages, how high of a consistent voltage range are you comfortable seeing, but especially 'spikes' in voltage? Mods are; rods, pistons, cam, VVT delete, HC blower with bypass controller, FIC 1200s, Fore return fuel system, and e85. TIA for any helpful input! I'm going to pull a spark plug out to see what's in it and check the gaps. I've got an external knock detection kit but it's very difficult to find a good spot on it. So, pretty much having to rely on the factory sensors for feedback
