Hello Guys,

I am kinda stumped with this. I have been trying to search and maybe I am getting somewhere.

If you fast shift the car to third gear and sometimes 4th, the car will close the TB and will NOT reopen upon commanded. The car will fall on its face. On another issue that is MAYBE related, the cruise control was NOT activating either. This is on a C6Z.

As a test... I disabled all TqManagement and maxed out all the tables... The problem appear to have gotten better and it's not having the same fall on its face symptom although you CAN feel that is not opening precisely as you want it.

The cruise control NOW works.

Here is a log of how it looks.



I have changed APP/TB in an attempt to fix the issue...

It appears the ECU is requesting the torque reduction for some reason and it's doing this.

Any help is greatly appreciated...
