    Fast bin had the spark you need at idle for that cam. I didn't look but shoot for 700-750 RPM. It will only be accurate to that RPM in Drive, not Park or Neutral.

    With a larger cam you need all the air possible at throttle blade to mix with fuel from injector. So after car is warmed up and driven then look at IAC count in drive about 15-20 and in park as long as it has a few like 1-5. Then your throttle blade minimum air is set right. That is if your fueling and spark are set right!
    Other possibility is the base timing is off.

    I wonder if has considered trying ASDU modified for a V6.

    With bypass wire disconnected?

    ASDU is a factory 5.7L auto and my choice for all V6 or conversions. To start tuning a V6 the only change needed is Cylinder count from 8 to 6. With yours I would also add Fast timing table and the VE you have worked on.

    have you set your TPS to 0.70 vdc at closed position, it could be causing a lot of your idle issues??? just a thought

    Should be good to go at .55 volts the TPS self zeros based on the lowest voltage it recieves.

    I also stumbled across a jewel of information regarding using this cam. Edelbrock suggest using their timing set due to some timing chains being machined to retard the cam. Retard cam timing would give lower vacuum, the look of a vacuum leak, weak off-idle power amoung other things.

    The log is no good and nothing will run right with a Error Code 51 set. So clear the code, if it comes back you have a chip issue.

    Your CEL at key on should come on, blink, then stay on till engine is started then go off.

    I looked at the log anyway and yes it is pig rich most everywhere.

    3/4 of that log was Open Loop so can't see BLM fueling adjustments, looks like it finally went closed loop when you started to drive.

    Temp after a huge long warm up was only 165f, but then did get to 180s when driving, so I'd say way rich and keeping motor to cool at idle.

    No idle left at end of log so can't help much there.

    I'm looking at it now and so far pig rich still. Also an Async fueling bin... I hate Async fueling bins!

    What's your fuel pressure?

    Post up your bin that your using for this log.
