    Big cubes, big cam whipple help

    Cant get this girl to maintain an idle to save my life. Idle is set at 975, but she hunts roughly 200 rpms. will post a log tomorrow, but below is a rundown of what I have adjusted, then put back to stock values after not finding any benefit from changes. fuel trims are within 10%...

    Small/Large Throttle Commands- maybe i made bigger adjustments than needed, but lowering or raising these field didn't help.
    Throttle Body Airflow- think mine is good to go, but tried adding more air down low, NO HELP
    All TQ spark & Throttle TQ under the idle airflow tables, spent countless hours on these, NO HELP

    to be fair having a better understand on what P,I & D are would help, but it appears you have your desired idle then factors that come into play when the idle is x amount rpms higher or lower.

    6.1 based 426

    Make the same changes to the Small and Large range tables too.
