    Default Idle speed for LS6 cam

    What do you guys have your idle speed set at.

    The LS6 cam (12565308) has 24° "underlap", it should easily idle that low... are you having any particular idle problem...?

    What is MAP at idle...?

    Do you have auto trans or manual trans...?

    The stock Z06 files have idle set at 800 rpm (manual trans).

    Joecar, no idle issue just seems low. My map is 40kpa in gear. Just seems little slow of the idle. I'll guess bump it up intill it feels right. Now 800 seem alittle high for auto trans.
    Thanks for help.

    I idle my A4/Z06 cam at 800rpm and I loved it because it was very smooth. For giggles I had it idle at 520rpm once, just to see what it's like, and it started to develop this tiny lope.
