Relationship between VVT table and Ignition Advance.

[Sassimac]

Hello All...

I am wondering about the relationship between the VVT table and ignition advance.

My reason for further understanding is that I had a few degrees of knock at WOT around the 5000RPM point. I added a few degrees of extra timing on the VVT table at this point also. I am wondering if it is best to retard the cam slightly at this point, or retard the ignition advance at this point.

Thanks..!!

VVT and ignition timing are independent. VVT needs to be timed to optimize cylinder charging without reversion into the intake.
