Which pid to monitor dfco

[camaro10]

Working on my 2010 ss camaro. What do I log to actually see if it's active. Commanded af or lambda never changes its either stoich or pe value. And as far as I know one of the fuel system pids worked but just showed if it was in open or closed loop. Trying to work on high vacuum light load regions of the vve. Thanks!

Try the pid GM.STATE05.

[camaro10]

Awesome I'll try that, thanks!

I tried that but it is not supported on my car. I validated pids just to be sure and it did not help

Try GM.FSST
