Until today, I had only seen the knock lights come on (start up test) when I started the car. Today I replaced a leaking BOV and started seeing the 3 color knock lights beginning to show up under higher loads.

I listened through the "Det Cans" but did not hear knock. I logged in the UTEC - no knock from the stock sensor - I forgot to switch to the tuner to log it's sensor so I can't report on that.

The UTEC was in pass through mode (stock maps)

I was on 93 Oct - boost at 22 - a few spikes to 23 pulling through 1st through 4th gear.

AFR's all looked good or rich.

The new JDM DV was holding boost very well, the boost gauge is a mechanical Defi D, I think its's pretty close, reports high if anything.

Any ideas as to why I'm seeing the knock lights all of a sudden.
