Just need a reference on 4.0 SOHC spark curve and knock sensor operation. Maybe an old RonD post, etc.

Currently data logging the 2011, and watching my spark curve randomly dipping deep into negative territory.

Still fighting with this SOB SOHC after 5 years...

No idea. In the middle of a lobotomy on the stock PCM. Trying to figure out why this thing is still giving me fits. Even when I lock out closed loop, it still has zero power.
