LS7 Does strange things, here is a Log file

[stevegressel]

Sometimes my car will hang the throttle when in neutral. for instance, driving down the road, put in neutral, rev engine, and it hangs for 5 to 10 seconds. check 19:07:45 area in the log.
GM Stage 3 cam, all the other supporting mods.

any advice would be great.
thank you

You started new post ? Why ? check your old one .

This is a new issue i came across today.

[LS ROB]

just glanced at your Base Running Airflow and it is higher than boat dock gas. id start by lowering it quiet a bit. that will help with throttle hang.

[stevegressel]

I made a few changes to base running airflow, didn't seem to help much for the throttle hang on a rev (downshift rev).
Still have a few issues,
1) Idles up to 2000 or 3000 RPM when coming to a stop, then immediately drops to 1000 when the car stops. (very annoying / embarrassing when in traffic and the car starts revving to 3000 rpm while coming to a red light / stop sign.)
2) Throttle hang when hitting the gas, it wont just rev then come back to idle.
3) Still has a lot of cam surge at lower RPM.
4) Doesn't start unless I hold throttle pedal to the floor.
5) Doesn't want to shut off.

here are some logs and the tune.

see if this helps with your hanging idle. I was not able to view your logs. For whatever reason, it kept telling me that i cant view the log unless i upgrade to a newer version. Z06Tune1-braf.hpt

You might also want to change transmission shift airflow - p/n - to 1's.

I see hpt's at it again - forcing updates on everyone. I'm still not updating this computer!
