    Experienced tuners please have a look

    Hi guys, I've been tuning on this thing for a while now. Do a mod, tweak the tune. When I started I didn't know jack. Definitely learning as I go. As I learn I get a little more nervous about what I've done over time. I'm saving for Gregs training, and reading a lot, but wondering if I'm on track or if I'd be better off backing up and starting over.The only quirks(I think) I currently have are 1.slight hanging idle(only occasionally) 2.Hot restarts, elevated idle(again only occasionally) 3. weird idle w/ ac. I plan on using RussK's idle info tomorrow. I've attached a couple scans of normal driving and current tune. Any comments or opinions are appreciated.

    Thanks,
    Donnie

    Definitely use the Idle config. Get your IAC counts ~ 60, copy and paste the running airflow into your Base running airflow table in the idle tab. Not starting on hot starts, I raise startup and friction airflow values a few percent at a time until it works. Don't dial in the VE until the car is at operating temps. If it's lean on a cold start after the decay times out then try the OLFA table.
    Hanging idle after bumping the gas will usually require the throttle cracker and follower values to be adjusted, but if your running air flow table is too high, it can cause this as well. Have you set your throttle blade up and done an idle re-learn?

    Should I start over, or am I in the neighborhood?
