08 Z06 LS7 short Diesel after shut down

[IDEALG]

Anyone fix this problem yet?

2008 Z06 LS7 with ported heads and BTR stage 3 cam

2 issues

Doesn't always start up on it's own unless you press the gas pedal

Diesels after shut down for a second or two

I'm looking for solid advice here i know this has been discussed before i've read most of the posts here but haven't seen a solution to the dieseling problem
I think the dieseling is causing my random no start issue.

Other then that the car runs and drives perfect
For the no start issue i've tried
-Raising base idle airflow
-Raising start up airflow
These don't help

Started up fine on it's own this morning
Started up fine on it's own after warmed up and after it sat shut down for awhile
If i go for a drive and shut if off then try to start it back up within 5 minutes of shut down it will not start without applying a little throttle. Which makes me think the dieseling at shut down has something to do with it.

Looks like you would be in Power Enrichment all of the time. Map enabled at 15kpa and Pedal at 5%
Your VVE tables look like they need some work. All 4 are different also.

Common problem on the 2008 Z06 only. Swapping to a newer ECM clears it.

Kill the ignition and floor it at the same time. I bet it will fire right back up like a champ.

I know you've been battling this for awhile, was hoping you had a fix. 2010+ ECM ?

Yeah i fixed the VVE

Map is Stock settings, car is not supercharged.

5% pedal is not an issue

So I fixed the starting issue all it needed was some more Base Idle Airflow. I just wasn't adding enough to it last time.

The shut down Dieseling isn't as bad now it shuts down fairly quick and sometimes it shuts right down.

Only issue i'm trying to conquer now is some bucking under 1800 rpm mostly moving around parking lots. I lowered the timing in those areas and it seems to help but i still have somewhat of a rowing effect instead of a heavy buck. May just be something we have to live with with this cam.
