Hi,
I am working on a 2010 Camaro SS with an E38. Engine is not stock, it is a GMPP LS3/525 crate motor. My questions are really centering around idle.
I have a good feel for how to tune the idle well (been reading lots of tutorials and howtos), but one thing that is not touched on specifically is target idle timing. The stock tune is around 13* to 15* timing at idle.
The stock cam is 204/211 with 117 lsa.
The ls3/525 cam is 226/236 with 110 lsa.
What would a reasonable idle timing target be? i have looked around on the internet and many say that bigger cams should have more advance at idle, and that will lead to more torque at idle and smoother idle.
I plan on playing with some trial and error, but wonder if anyone has any pointers.
