JimX, I think your reliance on the factory knock snesor is a little bit misguided, when you have your PFC you'll see what I mean. It shows a knock level, that means virtually nothing, and it's up to the user to determine the safe knock level.
I think Steve was suggesting that tuning a Wolf is much quicker than the PFC with HC. Wolf comes with laptop software which is excellent, and really reduves the time it takes to tune. Even with the Datalogit ($1000?) which is a huge improvement over the HC the PFC will still take longer to tune.
I believe that the lastest range of Wolfs are coming out with a base map, how good it is I have no idea, maybe Steve can share his thoughts.
