title fairly self-explanatory. Decent size cam in an ls11. Automatic. Stall converter, aluminum flexplate.
Just trying to get thoughts on why this happens so i can investigate it in the tune.
why does it die when coming to a stop?

Zeroed out the direct airflow correction table. Seems to have helped. I think the corrections were compounding the issue, either correcting too slow or correcting down too much.
Still experimenting.
Which columns in B4515 did you zero...?
All of them for now.
Tried zeroing spark idle corrections first. Problem was unchanged. So I reversed that and did direct airflow.
please post file and datalog as well as mods.

+1 please post files.
sounds like you need more base airflow. this is what my truck was doing before I added air flow. I did RAFIG then added a bit to it.
I did have an issue afterwards where the truck was learned down too far so I think it's best to make sure the values to add learned airflow are larger than subtracting. this way it learns up faster than it learns down.
I'll look into that. Logs coming soon, been catching up with work.
turn rolling idle off or at least raise the speed that is considered 0 or whatever. then log coming to a stop.
you will probably see RPM just die off while MAP slowly rises to atmosphere.
are you electric throttle or cable?
