Set AFR and knock

[07heri]

Does the Delphi system automatically richen the AFR when it senses a knock?

Yes it does, at least it does when Data logging with TTS

Okay.  I was wondering why Set AFR came out of closed loop, 14.6 to 14.4, when it logged a knock.  There wasn't any Accel Enrich logged but it came out of closed loop, as well as pulled 2 degrees.  This was using PV.  Never noticed it before so thought to ask.  Thanks.
