    Default High Idle speed after driving

    Hi guys, noobie again
    I have recently installed a 216/220 cam
    I havent done the auto ve tune yet as im waiting for a wideband.
    I have adjusted the desired idle speeds tho to suit me, however, after the engine has reached full temp, the idle speed sits at around 1100-1200rpm
    The idle speed is set at around 760.
    When cold all is good.
    What am I missing?

    Thanks guys

    Have you done the rafig process yet? It sounds like your desired air is too high when warm.

    Have a look at this post from SSpdemon.
    http://forum.efilive.com/showpost.ph...54&postcount=4
    That will get you started. if you do a search for rafig you will find a few more posts with a bit more info.

    Ok another question regarding the rafig/rafpn.
    In the post it says I must use
    GM.IAC_LTD_DMA & GM.IAC_STD_DMA for RAFIG and
    GM.IAC_LTPN_DMA & GM.IAC_STPN_DMA for RAFPN
    So there are 2 PIDs for rafig and 2 for rafpn.

    Do I log each pid as explained in the post individually and add results to the
    b4307 one at a time? ie: I log GM.IAC_LTD_DMA then add results to b4307, then log GM.IAC_STD_DMA and also add results to b4307
