Need help with hot start problem

[High_Vettelocity]

It's an 03 Z06 with a G5X3, AFR heads and Stinger intake.
When the engine is cold, it starts fine, idles well right away, about 900 rpm and requires very little warm up before driving. Repeated starts will be fine as long as the engine is not up to temp. After it is warmed up, it runs fine and idles great provided you don't shut it off. If it's been off less than 1 hour. When you re-start, it will start right up, then drop to about 400 rpm barely running for 3 to 5 seconds then come up to nomal idle. After about 10% of hot starts, it dies and is very hard to re-start. (cranks a long time).

Any suggestions on how to tune this out without raising the normal idle speed. Thanks in advance.

You need to play with your idle air flow, and maybe your IAC also.

Try reducing the first three columns of your ve table.

I "assumed" he had done that with the cold starts right...

but you may be correct.

I did not tune the car, so I'm not sure what was done. I just downloaded a stock bin and will compare. All I've done is change the throttle follower so the rpms don't hang between shifts. Thanks for the input.
