I thought this might spark some interesting conversation here, so I propose a question - do you guys like or dislike artificial cam chop?
What is artificial cam chop? It's when a tuner intentionally builds some oscillation into the idle tune with the Idle Adaptive Spark Control Overspeed and Underspeed tables and cause the cars idle to bounce, or chop as the car oscillates between overspeed and underspeed on the target idle rpm. Typically, you'll hear this on a cammed LS.
Here are some very different sounding cammed idles, with essentially the same cam profile.
(My) GPI SS3 - zero artificial chop, we went for the smoothest, most natural 800rpm idle. It still bounces and surges a little - but it has 19* of overlap to contend with, so you wouldn't expect it to be rock solid.
GPI SS3 - essentially the same cam profile with significant artificial chop tuned in.
I'll start with my own preference, which is probably obvious by the tuning on my car - I like zero artificial chop. To me, the natural lope of the cam has a beauty all it's own, and the artificial chop is a little bit "try hard".
But that's just my opinion - certainly not a right or wrong answer here. I'm just interested to see what other peoples thoughts and preferences are like.
Tuners - do people typically ask for anything specific in their idle quality? I work very closely with my tuner, and I know I was very specific about what I wanted, but that's probably not the norm. Is there a standard you have?
