CM Idle dies at 0 mph, PK at 1+ mph!!
C6 Z06 LS7.

After 10-5 secs idle suddenly dies down then comes back up. Sometimes it dies completely.

But if the car is ROLLING 1+ mph it idles PERFECTLY.

The closest table I find that differentiates idle from a stop and a rolling is OL & CL > LTFT Idle Cell > Enable VSS and Disable VSS which I set to 0 mph. I have been working on this for a month.

Any tuners have any suggestions on tables switch this behavior?

HI there,
As soon as vehicle speed is seen, you are no longer in idle cell.
As of this writing, I am unaware of any aftermarket programmer that modifies this cell.
When other cells are changed, or the engine modified, this is changed.

It would be suggested to verify MAF frequency more than anything else. The PCM monitors THIS more than anything else at idle.

Allthebest, c4c5

Problem solved. Increasing the min ETC did the trick.
