Until that bit can be located, I would say you need to devise a filter around all the DFCO enable/disable settings in your tune.
It is my understanding that anytime the PCM is not commanding stoichiometry it is in open loop fuel mode. Have you tried logging open/closed loop mode to see if it corresponds with the frames where you believe DFCO to be active?
Alternatively, there is another flag called "Fuel Learn" which I assume would be off when in DFCO - don't want the PCM adjusting fuel trims based on DFCO cells.
Open/Closed loop and Fuel Learn are both in pid {GM.STATE05}

Before asking for help, please read this.
Thanks Paul, I'll give that a look. When in DFCO the commanded AFR does not change so could not be used as a filter criteria (commaded will still be 14.7 for exacmpe but actualy WB02 will read 19.5+).
I'll check out STATE05 and let ya know

Actually.. I'm running in Open Loop fuel mode all the time so learning will not be occuring at any point, either while DFCO is ative or not :(
I'll still log STATE05 and see if this is infact the case.

DFCO state Bit has been located, we will add it in to the next update, it is actually in GM.STATE05 you just can't see it yet.Originally Posted by TAQuickness

OK, now I have another question... How do you use part of a STATE PID in a filter?
For example: STATE05 represents a number of different Boolean states and looking in the F9 (Data) tab you can see the STATE PID is expanded into a number of individual values.
How does one use one of those values in a filter? I'm preparing for when the DFCO PID is available.
